Method Detail

apply

public Collection<Node> apply(RDFBackend<Node> backend,
                     Node context,
                     Collection<Node>... args)
                       throws IllegalArgumentException

Description copied from interface: NodeFunction

Apply the function to the list of nodes passed as arguments and return the result as type T. Throws IllegalArgumentException if the function cannot be applied to the nodes passed as argument or the number of arguments is not correct.

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

args - a nested list of KiWiNodes

Returns:

Throws:

IllegalArgumentException

calc

protected Node calc(RDFBackend<Node> backend,
        Collection<Node> arg)

getDescription

public String getDescription()

Description copied from interface: NodeFunction

A short human-readable description of what the node function does.

Returns:

getSignature

public String getSignature()

Description copied from interface: NodeFunction

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:

getLocalName

public String getLocalName()
