org.topbraid.shacl.multifunctions.AbstractMultiFunction

org.topbraid.shacl.multifunctions.AbstractNativeMultiFunction

All Implemented Interfaces:

MultiFunction

Direct Known Subclasses:

AbstractMultiFunction1

public abstract class AbstractNativeMultiFunction
extends AbstractMultiFunction

Base class for all natively (Java) implemented MultiFunctions. They are initialized without the metadata (parameter declarations etc) but that will be added once the corresponding .api. file will be reached.

Description copied from interface: MultiFunction

Executes the multi-function for a given list of arguments.

Parameters:

args - the argument values, matching the declared parameters from left to right

activeGraph - the currently active query graph

dataset - the DatasetGraph to operate on

Returns:

a QueryIterator with name-value pairs
