Detailed Description

This is an implementation of the Iterator interface.

It will traverse the tree and find text/space/tab Node sequences.

Note: Once the XML Tree is parsed, then the Iterator will be a snapshot of that tree. That means even the tree is modified later, then the cached paragraph Node list will not be updated accordingly. For this reason and for performance reasons this Iterator does not support any operation methods such as insert, remove or replace. The main purpose of this Iterator is to be used with difference, not with merge.

Constructor & Destructor Documentation

TextNodeIterator()

org.openoffice.xmerge.merger.diff.TextNodeIterator.TextNodeIterator ( Node  node )

inline

Standard constructor.

Parameters

node	The initial root Node.

Definition at line 45 of file TextNodeIterator.java.

Member Function Documentation

nodeSupported()

boolean org.openoffice.xmerge.merger.diff.TextNodeIterator.nodeSupported ( Node  node )

inlineprotected

Overwrite the parent nodeSupported method.

Only text Node objects are supported.

Parameters

node	Node to check.

Returns

true if the Node is supported, false otherwise.
