Class NodeValueCharIterator

java.lang.Object
  net.sf.mmm.util.xml.base.NodeValueCharIterator

All Implemented Interfaces:

CharIterator

 class NodeValueCharIterator
extends Object
implements CharIterator

This is an implementation of CharIterator that iterates the characters of the value(s) of a single node or a node-list.

Since:

1.0.2

Field Summary

private int	nodeIndex The current index in nodeList.
private NodeList	nodeList
private String	value The current node-value.
private int	valueIndex The current index in value.
private int	valueLength The length of the current value.

END_OF_ITERATOR

Constructor Summary

NodeValueCharIterator(Node singleNode)
The constructor.

NodeValueCharIterator(NodeList nodeList)
The constructor.

Method Summary

boolean	hasNext() This method determines whether there is a next char available or the end of this iterator has been reached.
char	next() This method returns the next character to iterate or CharIterator.END_OF_ITERATOR if the end of this iterator has been reached.

Field Detail

nodeList

private final NodeList nodeList

See Also:

NodeValueCharIterator(NodeList)

nodeIndex

private int nodeIndex

The current index in nodeList.

value

private String value

The current node-value.

valueLength

private int valueLength

The length of the current value.

valueIndex

private int valueIndex

The current index in value.

Constructor Detail

NodeValueCharIterator

public NodeValueCharIterator(NodeList nodeList)

The constructor.

Parameters:

nodeList - is the NodeList containing the Nodes with the values to iterate char by char.

NodeValueCharIterator

public NodeValueCharIterator(Node singleNode)

The constructor.

Parameters:

singleNode - is the single Node with the value to iterate char by char.

Method Detail

hasNext

public boolean hasNext()

This method determines whether there is a next char available or the end of this iterator has been reached.

Specified by:

hasNext in interface CharIterator

Returns:

true if there is at least one next char available, or false if the end of this iterator has been reached and further calls of CharIterator.next() will return CharIterator.END_OF_ITERATOR.

See Also:

CharIterator.next(), Iterator.hasNext()

next

public char next()

This method returns the next character to iterate or CharIterator.END_OF_ITERATOR if the end of this iterator has been reached. If CharIterator.END_OF_ITERATOR is returned further calls will always return CharIterator.END_OF_ITERATOR.

Specified by:

next in interface CharIterator

Returns:

the next character or CharIterator.END_OF_ITERATOR if the end of this iterator has been reached.

Iterator.next()
