Class XMLWhiteSpaceHandler


public class XMLWhiteSpaceHandler
extends java.lang.Object

Class encapsulating the functionality for white-space-handling during refinement stage. The handleWhiteSpace() methods are called during FOTree-building and marker-cloning:

Each time one of the variants is called, white-space is handled for all FOText or Character nodes that were added:

The iteration always starts at firstTextNode, goes on until the last text-node is reached, and deals only with FOText or Character nodes.
Note: if the method is called from an inline's endOfNode(), there is too little context to decide whether trailing white-space may be removed, so the pending inline is stored in a List, together with an iterator for which the next() method returns the first in the trailing sequence of white- space characters. This List is processed again at the end of the ancestor block.

Method Summary

void
handleWhiteSpace(FObjMixed fo, FONode firstTextNode)
Handle white-space for the fo that is passed in, starting at firstTextNode (when a nested FO is encountered)
void
handleWhiteSpace(FObjMixed fo, FONode firstTextNode, FONode nextChild)
Handle white-space for the fo that is passed in, starting at firstTextNode
