Constructor Detail

PjDictionary

public PjDictionary()

Creates an empty dictionary.

PjDictionary

public PjDictionary(java.util.Hashtable h)

Creates a dictionary as a wrapper around a Hashtable.

Parameters:

h - the Hashtable to use for this dictionary.

Method Detail

getHashtable

public java.util.Hashtable getHashtable()

Returns the Hashtable used to represent this dictionary.

Returns:

the Hashtable used to represent this dictionary.

writePdf

public long writePdf(java.io.OutputStream os)
              throws java.io.IOException

Writes this dictionary to a stream in PDF format.

Overrides:

writePdf in class BaseObject

Parameters:

os - the stream to write to.

Returns:

the number of bytes written.

Throws:

java.io.IOException - if an I/O error occurs.

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Returns a deep copy of this object.

Overrides:

clone in class BaseObject

Returns:

a deep copy of this object.

Throws:

java.lang.CloneNotSupportedException - if the instance can not be cloned.

cloneHt

protected java.util.Hashtable cloneHt()
                               throws java.lang.CloneNotSupportedException

renumber

public void renumber(java.util.Hashtable map)

Renumbers object references within this object. This method calls itself recursively to comprehensively renumber all objects contained within this object.

Overrides:

renumber in class PjObject

Parameters:

map - the table of object number mappings. Each object number is looked up by key in the hash table, and the associated value is assigned as the new object number. The map hash table should consist of PjNumber keys and PjReference values.

hget

protected PjObject hget(PjName name)
                 throws InvalidPdfObjectException

hgetReference

protected PjReference hgetReference(PjName name)
                             throws InvalidPdfObjectException
