Parameters:

context - the context of the execution. Same as using the NodeSelector '.' as parameter.

args - a nested list of KiWiNodes

Returns:

Throws:

IllegalArgumentException

getLocalName

public String getLocalName()

Return the representation of the NodeFunction or NodeSelector in the RDF Path Language

Specified by:

getLocalName in class AutoRegisteredLDPathFunction

Returns:

getSignature

public String getSignature()

A string describing the signature of this node function, e.g. "fn:content(uris : Nodes) : Nodes". The syntax for representing the signature can be chosen by the implementer. This method is for informational purposes only.

Returns:
