                     throws XPathException

Description copied from class: ScalarSystemFunction

Abstract method that must be supplied in subclasses to perform the evaluation

Specified by:

evaluate in class ScalarSystemFunction

Parameters:

item - the supplied argument

context - the dynamic context

Returns:

the result of the evaluation. May be null indicating the result is an empty sequence.

Throws:

XPathException - if a dynamic error occurs

nodeName

public static QNameValue nodeName(NodeInfo node)

getElaborator

public Elaborator getElaborator()

Make an elaborator for a system function call on this function

Overrides:

getElaborator in class SystemFunction

Returns:

a suitable elaborator; or null if no custom elaborator is available
