Class BiNode

java.lang.Object
  net.sourceforge.jeuclid.biparser.AbstractBiNode
      net.sourceforge.jeuclid.biparser.BiNode

All Implemented Interfaces:

IBiNode

public final class BiNode
extends AbstractBiNode

this class is used to store specific information about a composite xml-node. the node can have one child, many attributes and can be invalid

Version:

Constructor Summary

BiNode(int co, String ns, String n, Attributes a)
creates a new BiNode, length must be set afterwards. constructor does not create a DOM-node

Method Summary

void	addChild(IBiNode c) add a child to this node, if node has already a child, forward to child.
Node	createDOMSubtree(Document doc) create a DOM-tree from node and all children (recursive).
IBiNode	getChild() get the child of the node.
int	getLengthOfChildren() calculate the length of all children.
String	getNodeName() get the name of the node (tagname).
BiType	getType() get the type of node.
void	insert(BiTree biTree, int offset, int length, int totalOffset) insert characters to node.
void	remove(BiTree biTree, int offset, int length, int totalOffset) remove characters from 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
void	setChild(IBiNode c) set child for this node.
String	toString()
String	toString(int level) print biNode.

Constructor Detail

BiNode

public BiNode(int co,
              String ns,
              String n,
              Attributes a)

creates a new BiNode, length must be set afterwards. constructor does not create a DOM-node

Parameters:

co - offset to child from node begin (length of open tag)

ns - DOM-info

n - DOM-info

a - DOM-info

Method Detail

getNodeName

public String getNodeName()

get the name of the node (tagname).

Returns:

nodename

addChild

public void addChild(IBiNode c)

add a child to this node, if node has already a child, forward to child.

Parameters:

c - new child for this node

getChild

public IBiNode getChild()

get the child of the node.

Returns:

child

setChild

public void setChild(IBiNode c)

set child for this node.

Parameters:

c - new child for this node

getType

public BiType getType()

get the type of node.

Returns:

NODE

insert

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

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

NonIncrementalElementException - if the subtree contains an element which cannot be incrementally updated.

remove

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

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

NonIncrementalElementException - if the subtree contains an element which cannot be incrementally updated.

getLengthOfChildren

public int getLengthOfChildren()

calculate the length of all children.

Returns:

length of children

createDOMSubtree

public Node createDOMSubtree(Document doc)
