Method Detail

expandedQName

public static QNameValue expandedQName(StringValue namespace,
                                       StringValue lexical)
                                throws XPathException

Throws:

XPathException

call

public Sequence call(XPathContext context,
                     Sequence[] arguments)
              throws XPathException

Evaluate the expression

Parameters:

context - the dynamic evaluation context

arguments - the values of the arguments, supplied as Sequences

Returns:

the result of the evaluation, in the form of a Sequence

Throws:

XPathException - if a dynamic error occurs during the evaluation of the expression

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
