Class ListMapAsObject

All Implemented Interfaces:

public class ListMapAsObject extends BaseBuiltin
For each element in the RDF list (third argument) it asserts triples with that as the object and subject and predicate given by arguments one and two. A strange and hacky function, only usable in the head of forward rules.

  • Method Details

    • getName

      public String getName()
      Return a name for this builtin, normally this will be the name of the functor that will be used to invoke it.
    • getArgLength

      public int getArgLength()
      Return the expected number of arguments for this functor or 0 if the number is flexible.
      Specified by:
      getArgLength in interface Builtin
      getArgLength in class BaseBuiltin
    • headAction

      public void headAction(Node[] args, int length, RuleContext context)
      This method is invoked when the builtin is called in a rule head. Such a use is only valid in a forward rule.
      Specified by:
      headAction in interface Builtin
      headAction in class BaseBuiltin
      args - the array of argument values for the builtin, this is an array of Nodes.
      length - the length of the argument list, may be less than the length of the args array for some rule engines
      context - an execution context giving access to other relevant data
