All Implemented Interfaces:

IBiNode

public final class TextNode
extends AbstractBiNode

this class is used to store specific information about a text node. the node cannot have a child nor a sibling

Constructor Summary

TextNode(int length, String t)
creates a new TextNode, constructor does not create a DOM-node.

Method Summary

Node	createDOMSubtree(Document doc) create a DOM-textnode.
void	forwardToSibling(boolean insert, BiTree biTree, int offset, int length, int totalOffset) forward insert/remove to sibling not allowed at a TextNode.
String	getText() get the text of TextNode.
BiType	getType() get the type of node.
void	insert(BiTree biTree, int offset, int length, int totalOffset) insert characters in TextNode, always reparse parent node.
void	remove(BiTree biTree, int offset, int length, int totalOffset) remove characters in TextNode, always reparse parent node.
TextPosition	searchNode(Node node, int totalOffset) search a DOM node in this node. if nodes are equal return offset to begin of inputtext, else null
String	toString()
String	toString(int level) print biNode.

Constructor Detail

TextNode

public TextNode(int length,
                String t)

creates a new TextNode, constructor does not create a DOM-node.

Parameters:

length - length of child

t - DOM-info

Method Detail

getType

public BiType getType()

get the type of node.

Returns:

TEXT

insert

public void insert(BiTree biTree,
                   int offset,
                   int length,
                   int totalOffset)
            throws ReparseException

insert characters in TextNode, always reparse parent node. insert characters to node.

Parameters:

biTree - reference to BiTree to which this node contains

offset - position to insert characters

length - number of characters to insert

totalOffset - offset of node to begin of text

Throws:

ReparseException - if a reparse at upper level is needed

remove

public void remove(BiTree biTree,
                   int offset,
                   int length,
                   int totalOffset)
            throws ReparseException

remove characters in TextNode, always reparse parent node. remove characters from node.

Parameters:

biTree - reference to BiTree to which this node contains

offset - position to remove characters

length - number of characters to remove

totalOffset - offset of node to begin of text

Throws:

ReparseException - if a reparse at upper level is needed

forwardToSibling

public void forwardToSibling(boolean insert,
                             BiTree biTree,
                             int offset,
                             int length,
