Create or lookup an anonymous instance of a property value. Syntax of the call is:
    makeInstance(X, P, D, T) or makeInstance(X, P, T)
where X is the instance and P the property for which a temporary value is required, T will be bound to the temp value (a bNode) and D is an optional type cor the T value.

    • 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.
    • bodyCall

      public boolean bodyCall(Node[] args, int length, RuleContext context)
      This method is invoked when the builtin is called in a rule body.
      Specified by:
      bodyCall in interface Builtin
      bodyCall in class BaseBuiltin
      args - the array of argument values for the builtin, this is an array of Nodes, some of which may be Node_RuleVariables.
      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
      return true if the buildin predicate is deemed to have succeeded in the current environment
