Method Detail

value

public int value()

Gets the axis value.

Returns:

the axis value

iterator

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

Gets the iterator for a specific XPath axis.

Parameters:

contextNode - the current context node to work from

support - the additional context information

Returns:

an iterator for the axis

Throws:

UnsupportedAxisException

namedAccessIterator

public Iterator namedAccessIterator(Object contextNode,
                                    ContextSupport support,
                                    String localName,

                             throws UnsupportedAxisException

Gets the iterator for a specific XPath axis that supports named access.

Parameters:

contextNode - the current context node to work from

support - the additional context information

localName - the local name of the nodes to return

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

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

Throws:

UnsupportedAxisException

supportsNamedAccess

public boolean supportsNamedAccess(ContextSupport support)

Does this axis support named access?

Parameters:

support - the additional context information

Returns:

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