Class NamespaceCodeIterator

java.lang.Object
  net.sf.saxon.tree.util.NamespaceCodeIterator

All Implemented Interfaces:

IntIterator

public class NamespaceCodeIterator
extends Object
implements IntIterator

This class provides an iterator over the namespace codes representing the in-scope namespaces of any node. It relies on nodes to implement the method NodeInfo.getDeclaredNamespaces(int[]).

The result does not include the XML namespace.

Method Summary

boolean	hasNext() Test whether there are any more integers in the sequence
static IntIterator	iterateNamespaces(NodeInfo element) Factory method: create an iterator over the in-scope namespace codes for an element
int	next() Return the next integer in the sequence.
static void	sendNamespaces(NodeInfo element, Receiver receiver) Send all the in-scope namespaces for a node to a specified receiver

Method Detail

iterateNamespaces

public static IntIterator iterateNamespaces(NodeInfo element)

Factory method: create an iterator over the in-scope namespace codes for an element

Parameters:

element - the element (or other node) whose in-scope namespaces are required. If this is not an element, the result will be an empty iterator

Returns:

an iterator over the namespace codes. A namespace code is an integer that represents a prefix-uri binding; the prefix and URI can be obtained by reference to the name pool. This iterator will represent all the in-scope namespaces, without duplicates, and respecting namespace undeclarations. It does not include the XML namespace.

sendNamespaces

public static void sendNamespaces(NodeInfo element,
                                  Receiver receiver)
                           throws XPathException

Send all the in-scope namespaces for a node to a specified receiver

Parameters:

element - the element in question (the method does nothing if this is not an element)

receiver - the receiver to which the namespaces are notified

Throws:

XPathException

hasNext

public boolean hasNext()

Description copied from interface: IntIterator

Test whether there are any more integers in the sequence

Specified by:

hasNext in interface IntIterator

Returns:

true if there are more integers to come

next

public int next()

Description copied from interface: IntIterator

Return the next integer in the sequence. The result is undefined unless hasNext() has been called and has returned true.

Specified by:

next in interface IntIterator

Returns:

the next integer in the sequence
