bodyCall
(Node[] args, int length, RuleContext context) This method is invoked when the builtin is called in a rule body.int
Return the expected number of arguments for this functor or 0 if the number is flexible.getName()

- Parameters:
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 enginescontext
- an execution context giving access to other relevant data- Returns:
- return true if the buildin predicate is deemed to have succeeded in the current environment
