Method Detail

iterator

public Iterator iterator(Object contextNode,
                ContextSupport support)
                  throws UnsupportedAxisException

Gets the iterator for the child axis.

Specified by:

iterator in class IterableAxis

Parameters:

contextNode - the current context node to work from

support - the additional context information

Returns:

an iterator over the children of the context node

Throws:

UnsupportedAxisException - if the child axis is not supported

namedAccessIterator

public Iterator namedAccessIterator(Object contextNode,
                           ContextSupport support,
                           String localName,
                           String namespacePrefix,
                           String namespaceURI)
                             throws UnsupportedAxisException

Gets an iterator for the child XPath axis that supports named access.

Overrides:

namedAccessIterator in class IterableAxis

Parameters:

contextNode - the current context node to work from

support - the additional context information

localName - the local name of the children to return

namespacePrefix - the prefix of the namespace of the children to return

namespaceURI - the URI of the namespace of the children to return

Returns:

an iterator over the children of the context node

Throws:

UnsupportedAxisException - if the child axis is not supported by the model

supportsNamedAccess

public boolean supportsNamedAccess(ContextSupport support)

Does this axis support named access?

Overrides:

supportsNamedAccess in class IterableAxis

Parameters:

support - the additional context information

Returns:

true if named access supported. If not iterator() will be used
