Method Detail

registerNamespace

public void registerNamespace(java.lang.String prefix,
                              java.lang.String namespaceURI)

Registers a namespace prefix.

Parameters:

prefix - A namespace prefix

namespaceURI - A URI for that prefix

setNamespaceContextPointer

public void setNamespaceContextPointer(NodePointer pointer)

Register a namespace for the expression context.

getNamespaceContextPointer

public Pointer getNamespaceContextPointer()

getNamespaceURI

public java.lang.String getNamespaceURI(java.lang.String prefix)

Given a prefix, returns a registered namespace URI. If the requested prefix was not defined explicitly using the registerNamespace method, JXPathContext will then check the context node to see if the prefix is defined there. See setNamespaceContextPointer.

Parameters:

prefix - The namespace prefix to look up

Returns:

namespace URI or null if the prefix is undefined.

getPrefix

public java.lang.String getPrefix(java.lang.String namespaceURI)

isSealed

public boolean isSealed()

seal

public void seal()

clone

public java.lang.Object clone()
