peek

public Node peek()
          throws ParserException

Deprecated.

Description copied from interface: PeekingIterator

Fetch a node without consuming it. Subsequent calls to peek() will return subsequent nodes. The node returned by peek() will never be a node already consumed by nextHTMLNode().

For example, say there are nodes <H1><H2><H3><H4><H5>, this is the nodes that would be returned for the indicated calls:

 peek()         H1
 peek()         H2
 nextHTMLNode() H1
 peek()         H3
 nextHTMLNode() H2
 nextHTMLNode() H3
 nextHTMLNode() H4
 peek()         H5
 

Specified by:

peek in interface PeekingIterator

Returns:

The next node that would be returned by nextHTMLNode() or the node after the last node returned by peek(), whichever is later in the stream. or null if there are no more nodes available via the above rules.

Throws:

ParserException

push

public void push(Node node)

Deprecated.

Makes node the next Node that will be returned.

Parameters:

node - The node to return next.

hasMoreNodes

public boolean hasMoreNodes()
                     throws ParserException

Deprecated.

Check if more nodes are available.

Specified by:

hasMoreNodes in interface NodeIterator

Returns:

true if a call to nextNode() will succeed.

Throws:

ParserException

nextNode

public Node nextNode()
              throws ParserException

Deprecated.

Get the next node.

Specified by:

nextNode in interface NodeIterator

Returns:

The next node in the HTML stream, or null if there are no more nodes.

Throws:

ParserException
