All Implemented Interfaces:

javax.accessibility.Accessible, java.awt.event.ActionListener, java.util.EventListener, java.awt.image.ImageObserver, JsetValueCallback, java.awt.MenuContainer, javax.swing.RootPaneContainer, java.io.Serializable, treeCallback, javax.swing.WindowConstants

public class gclient

extends javax.swing.JFrame

implements treeCallback, java.awt.event.ActionListener, JsetValueCallback

Main ganymede client class. When glogin is run and a user logs in to the server, the client obtains a Session reference that allows it to talk to the server on behalf of a user, and a single instance of this class is created to handle all client GUI and networking operations for that user.

gclient creates a windowPanel object to contain internal object and query windows on the right side of a Swing JSplitPane. The left side contains a custom treeControl GUI component displaying object categories, types, and instances for the user to browse and edit.

cachedLists

protected objectCache cachedLists

Our main cache, keeps information about all objects we've learned about via QueryResult's returned to us by the server.

We can get QueryResults from the server by doing direct query calls on the server, or by calling choices() on an invid_field or on a string_field. Information from both sources may be integrated into this cache.

statusThread

public StatusClearThread statusThread

This thread is used to clear the statusLabel after some interval after it is set.

Whenever the gclient's setStatus method is called, this thread has a countdown timer started, which will clear the status label if it is not reset by another call to setStatus.

securityThread

public SecurityLaunderThread securityThread

This thread is set up to launder RMI build status updates from the server.

In some versions of Sun's JDK, RMI callbacks are not allowed to manipulate the GUI event queue. To get around this, this securityThread is created to launder these RMI callbacks so that the Swing event queue is messed with by a client-local thread.

wizardActive

private int wizardActive

this is true during the handleReturnVal method, while a wizard is active. If a wizard is active, don't allow the window to close.

Constructor Detail

gclient

public gclient(Session s,
               glogin g)

This is the main constructor for the gclient class.. it handles the interactions between the user and the server once the user has logged in.

Parameters:

s - Connection to the server created for us by the glogin applet.

g - The glogin applet which is creating us.

Method Detail

stackTrace

public static java.lang.String stackTrace(java.lang.Throwable thing)

This is a convenience method used by the server to get a stack trace from a throwable object in String form.

start

public void start()

This method handles the start-up tasks after the gclient has gotten initialized. Called by glogin.

getTemplateVector

public java.util.Vector getTemplateVector(short id)

Returns a vector of FieldTemplate's.

Parameters:

                                      short fieldId)

Returns a FieldTemplate based on the short type id for the containing object and the short field id for the field.

getTemplateVector

public java.util.Vector getTemplateVector(java.lang.Short id)

Returns a vector of FieldTemplate's listing fields and field informaton for the object type identified by id.

Parameters:

id - The id number of the object type to be returned the base id.

clearCaches

public void clearCaches()

Clears out the client's objectCache, which holds object labels, and activation status for invid's returned by various query and db_field choices() operations.

getObjectList

public objectList getObjectList(java.lang.Short id,
                                boolean showAll)

Gets a list of objects from the server, in a form appropriate for use in constructing a list of nodes in the tree under an object type (object base) folder.

This method supports client-side caching.. if the list required has already been retrieved, the cached list will be returned. If it hasn't, getObjectList() will get the list from the server and save a local copy in an objectCache for future requests.

update

public void update(java.awt.Graphics g)

By overriding update(), we can eliminate the annoying flash as the default update() method clears the frame before rendering.

Overrides:

update in class javax.swing.JFrame

getSession

public final Session getSession()

Get the session

getErrorImage

public final java.awt.Image getErrorImage()

Loads and returns the error Image for use in client dialogs.

Once the image is loaded, it is cached for future calls to getErrorImage().

getQuestionImage

public final java.awt.Image getQuestionImage()

Loads and returns the question-mark Image for use in client dialogs.

Once the image is loaded, it is cached for future calls to getQuestionmage().

getBaseNames

public final java.util.Hashtable getBaseNames()

Returns a hash mapping BaseDump references to their title.

Checks to see if the baseNames was loaded, and if not, it loads it. Always use this instead of trying to access baseNames directly.

getBaseList

public final java.util.Vector getBaseList()

Returns a Vector of BaseDump objects, providing a local cache of Base references that the client consults during operations.

Checks to see if the baseList was loaded, and if not, it loads it. Always use this instead of trying to access the baseList directly.

getBaseMap

public java.util.Hashtable getBaseMap()

Returns a hash mapping Short Base id's to BaseDump objects.

Checks to see if the baseMap was loaded, and if not, it loads it. Always use this instead of trying to access the baseMap directly.

getBaseToShort

public java.util.Hashtable getBaseToShort()

Returns a hashtable mapping BaseDump references to their object type id in Short form. This is a holdover from a time when the client didn't create local copies of the server's Base references.

Checks to see if the basetoShort was loaded, and if not, it loads it. Always use this instead of trying to access the baseToShort directly.

getObjectType

public java.lang.String getObjectType(Invid objId)

Returns the type name for a given object.

If the loader thread hasn't yet downloaded that information, this method will block until the information is available.

Sets text in the status bar, with a 5 second countdown before the status bar is cleared.

Parameters:

status - The text to display

setStatus

public final void setStatus(java.lang.String status,
                            int timeToLive)

Sets text in the status bar, with a defined countdown before the status bar is cleared.

Parameters:

status - The text to display

timeToLive - Number of seconds to wait until clearing the status bar. If zero or negative, the status bar timer will not clear the field until the status bar is changed by another call to setStatus.

softTimeout

public final void softTimeout()

This method is triggered by the Ganymede server if the client is idle long enough. This method will downgrade the user's login to a minimum privilege level if possible, requiring the user to enter their admin password again to regain admin privileges.

setBuildStatus

public final void setBuildStatus(java.lang.String status)

Sets text in the build status bar

Parameters:

status - The text to display

getSelectedObjectNode

public InvidNode getSelectedObjectNode()

Shows the About... dialog.

showCredits

public void showCredits()

Shows the credits dialog.

showMOTD

public void showMOTD()

Shows the server's message of the day in a dialog.

                                   java.lang.String message)

Pops up an error dialog.

showErrorMessage

public final void showErrorMessage(java.lang.String title,
                                   java.lang.String message,
                                   java.awt.Image icon)

Show an error dialog.

Parameters:

title - title of dialog.

message - Text of dialog.

icon - optional icon to display.

setWaitCursor

public void setWaitCursor()

Set the cursor to a wait cursor(usually a watch.)

setNormalCursor

public void setNormalCursor()

Set the cursor to the normal cursor(usually a pointer.)

This is dependent on the operating system.

somethingChanged

public final void somethingChanged()

This indeicates that something in the database was changed, so cancelling this transaction will have consequences.

This should be called whenever the client makes any changes to the database. That includes creating objects, editting fields of objects, removing objects, renaming, expiring, deleting, inactivating, and so on. It is very important to call this whenever something might have changed.

setSomethingChanged

private void setSomethingChanged(boolean state)

Sets or clears the client's somethingChanged flag.

getSomethingChanged

public boolean getSomethingChanged()

True if something has been changed since the last commit/cancel

isApplet

public boolean isApplet()

True if we are in an applet context, meaning we don't have access to local files, etc.

handleReturnVal

public ReturnVal handleReturnVal(ReturnVal retVal)

This method takes a ReturnVal object from the server and, if necessary, runs through a wizard interaction sequence, possibly displaying several dialogs before finally returning a final result code.

Use the ReturnVal returned from this function after this function is called to determine the ultimate success or failure of any operation which returns ReturnVal, because a wizard sequence may determine the ultimate result.

This method should not be synchronized, since handleReturnVal may pop up modal (thread-blocking) dialogs, and if we we synchronize this, some Swing or AWT code seems to block on our synchronization when we do pop-up dialogs. It's not any of my code, so I assume that AWT tries to synchronize on the frame when parenting a new dialog.

createToolbar

javax.swing.JToolBar createToolbar()

Creates and initializes the client's toolbar.

clearTree

void clearTree()

Clears out the client's tree.

All Nodes will be removed, and the Category and BaseNodes will be rebuilt. No InvidNodes will be added.

buildTree

void buildTree()
         throws java.rmi.RemoteException

This method builds the initial data structures for the object selection tree, using the base information in the baseHash hashtable gained from the Loader thread.

recurseDownCategories

void recurseDownCategories(CatTreeNode node,
                           Category c)
                     throws java.rmi.RemoteException

Recurses down the category tree obtained from the server, loading the client's tree with category and object folder nodes.

insertCategoryNode

treeNode insertCategoryNode(CategoryNode node,
                            treeNode prevNode,
                            treeNode parentNode)
                      throws java.rmi.RemoteException

Helper method for building tree

refreshObjects

void refreshObjects(BaseNode node,
                    boolean doRefresh)
              throws java.rmi.RemoteException

This method is used to update the list of object nodes under a given base node in our object selection tree, synchronizing the tree with the actual objects on the server.

Parameters:

node - Tree node corresponding to the object type being refreshed in the client's tree.

doRefresh - If true, causes the tree to update its display.

refreshTreeAfterCommit

void refreshTreeAfterCommit()
                      throws java.rmi.RemoteException

Updates the tree for the nodes that might have changed.

This method fixes all the icons, removing icons that were marked as to-be-deleted or dropped, and cleans out the various hashes. Only call this when commit is clicked. This replaces refreshTree(boolean committed), because all the refreshing to be done after a cancel is now handled in the cancelTransaction() method directly.

This method is precisely analagous in function to cleanUpAfterCancel(), except for use after a commit.

refreshChangedObjectHandles

public void refreshChangedObjectHandles(java.util.Vector paramVect,
                                        boolean afterCommit)

Queries the server for status information on a vector of invid's that were touched in some way by the client during the recent transaction. The results from the queries are used to update the icons in the tree.

Called by refreshTreeAfterCommit().

This method is called from refreshTreeAfterCommit().

Parameters:

paramVect - Vector of invid's to refresh.

afterCommit - If true, this method will update the client's status bar as it progresses.

refreshChangedObject

public void refreshChangedObject(Invid invid)

This method does the same thing as refreshChangedObjectHandles(), but for a single object only.

setIconForNode

public void setIconForNode(Invid invid)

Updates a database object's icon in the tree display. This method uses the various client-side caches and hashes to determine the proper icon for the node.

This method does not actually induce the tree to refresh itself, and may be called in bulk for a lot of nodes efficiently.

editObject

public void editObject(Invid invid)

Opens a new framePanel window to allow the user to edit an object.

Use this to edit objects, so gclient can keep track of the caches, tree nodes, and all the other dirty work. This should be the only place windowPanel.addWindow() is called for editing purposes.

Parameters:

invid - id for the object to be edited in the new window.

editObject

public void editObject(Invid invid,
                       java.lang.String objectType)

Opens a new framePanel window to allow the user to edit an object.

Use this to edit objects, so gclient can keep track of the caches, tree nodes, and all the other dirty work. This should be the only place windowPanel.addWindow() is called for editing purposes.

Parameters:

invid - id for the object to be edited in the new window.

objectType - String describing the kind of object being edited, used in the titlebar of the window created.

cloneObject

public db_object cloneObject(Invid origInvid)

Creates a new object on the server and opens a new client framePanel window to allow the user to edit the new object.

Parameters:

type - Type of object to be created

createObject

public db_object createObject(short type)

Creates a new object on the server and opens a new client framePanel window to allow the user to edit the new object.

Parameters:

type - Type of object to be created

viewObject

public void viewObject(Invid invid)

Opens a new framePanel window to view the object corresponding to the given invid.

viewObject

public void viewObject(Invid invid,
                       java.lang.String objectType)

Opens a new framePanel window to view the object corresponding to the given invid.

Parameters:

objectType - Type of the object to be viewed.. if this is null, the server will be queried to determine the type of object for the title-bar of the view object window. By providing it here from a local cache, and server-call can be saved.

deleteObject

public boolean deleteObject(Invid invid,
                            boolean showDialog)

Marks an object on the server as deleted. The object will not actually be removed from the database until the transaction is committed.

This method does a fair amount of internal bookkeeping to manage the client's tree display, status caching, etc.

inactivateObject

public boolean inactivateObject(Invid invid)

Marks an object on the server as inactivated. The object will not actually be removed from the database until the transaction is committed. Note that the inactivation request will typically cause a dialog to come back from the server requesting the user fill in parameters describing how the object is to be inactivated.

This method does a fair amount of internal bookkeeping to manage the client's tree display, status caching, etc.

reactivateObject

public boolean reactivateObject(Invid invid)

Reactivates an object that was previously inactivated. The object's status will not actually be changed in the database until the transaction is committed. Note that the reactivation request will typically cause a dialog to come back from the server requesting the user fill in parameters describing how the object is to be reactivated.

Typically reactivating an object involves clearing the removal date from I think you should call this from the expiration date panel if the date is cleared.

createObjectDialog

void createObjectDialog()

Show the create object dialog, let the user choose to create or not create an object.

editObjectDialog

void editObjectDialog()

Opens a dialog to let the user choose an object for editing, and if cancel is not chosen, the object is opened for editing.

If an object node is selected in the client's tree, the dialog will be pre-loaded with the type and name of the selected node.

viewObjectDialog

void viewObjectDialog()

Opens a dialog to let the user choose an object for viewing, and if cancel is not chosen, the object is opened for viewing.

If an object node is selected in the client's tree, the dialog will be pre-loaded with the type and name of the selected node.

inactivateObjectDialog

void inactivateObjectDialog()

Opens a dialog to let the user choose an object for inactivation, and if cancel is not chosen, the object is opened for inactivation.

If an object node is selected in the client's tree, the dialog will be pre-loaded with the type and name of the selected node.

deleteObjectDialog

void deleteObjectDialog()

Opens a dialog to let the user choose an object for deletion, and if cancel is not chosen, the object is opened for deletion.

If a node is selected in the client's tree, the dialog will be pre-loaded with the type and name of the selected object.

cloneObjectDialog

void cloneObjectDialog()

Opens a dialog to let the user choose an object for cloning, and if cancel is not chosen, the object is opened for cloning.

If a node is selected in the client's tree, the dialog will be pre-loaded with the type and name of the selected object.

changePersona

void changePersona(boolean requirePassword)

Creates and presents a dialog to let the user change their selected persona.

gclient's personaListener reacts to events from the persona change dialog and will react appropriately as needed. This method doesn't actually do anything other than display the dialog.

PersonaDialog is modal, however, so this method will block until the user makes a choice in the dialog box.

getPersonaDialog

PersonaDialog getPersonaDialog()

Returns a reference to the most recently created persona dialog.

logout

void logout()

Logs out from the client.

This method does not do any checking, it just logs out.

chooseFilter

public void chooseFilter()

Create a custom query filter.

The filter is used to limit the output on a query, so that supergash can see the world through the eyes of a less-privileged persona. This seemed like a good idea at one point, not sure how valuable this really is anymore.

chooseDefaultOwner

public void chooseDefaultOwner(boolean forcePopup)

Chooses the default owner group for a newly created object.

This must be called before Session.create_db_object is called.

defaultOwnerChosen

public boolean defaultOwnerChosen()

True if a default owner has already been chosen.

OKToProceed

boolean OKToProceed()

Check for changes in the database before logging out.

This checks to see if anything has been changed. Basically, if edit panels are open and have been changed in any way, then somethingChanged will be true and the user will be warned. If edit panels are open but have not been changed, then it will return true(it is ok to proceed).

updateNotePanels

void updateNotePanels()

Updates the note panels in the open windows.

The note panel doesn't have a listener on the TextArea, so when a transaction is committed, this must be called on each notePanel in order to update the server.

This basically does a field.setValue(notesArea.getValue()) on each notesPanel.

THIS IS A PRETTY BIG HACK.

commitTransaction

public void commitTransaction()

Commits the currently open transaction on the server. All changes made by the user since the last openNewTransaction() call will be integrated into the database on the Ganymede server.

For various reasons, the server may reject the transaction as incomplete. Usually this will be a non-fatal error.. the user will see a dialog telling him what else needs to be filled out in order to commit the transaction. In this case, commitTransaction() will have had no effect and the user is free to try again.

If the transaction is committed successfully, the relevant object nodes in the tree will be fixed up to reflect their state after the transaction is committed. commitTransaction() will close all open editing windows, and will call openNewTransaction() to prepare the server for further changes by the user.

cancelTransaction

public void cancelTransaction()

Cancels the current transaction. Any changes made by the user since the last openNewTransaction() call will be forgotten as if they never happened. The client's tree display will be reverted to the state it was when the transaction was started, and all open windows will be closed.

cleanUpAfterCancel

private void cleanUpAfterCancel()

Cleans up the tree and gclient's caches.

This method is precisely analagous in function to refreshTreeAfterCommit(), except for use after a cancel, when nodes marked as deleted are not removed from the tree, and nodes marked as created are not kept.

openNewTransaction

private void openNewTransaction()

Initializes a new transaction on the server

toggleToolBar

void toggleToolBar()

toggles the toolbar on and off
