getName
public java.lang.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 interfaceBuiltin
- Overrides:
bodyCall
in classBaseBuiltin
- 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
-
headAction
public void headAction(Node[] args, 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. Exected args are the instance to be annotated, the property to use and the type of the resulting bNode.- Parameters:
args
- the array of argument values for the builtin, this is an array of Nodes.context
- an execution context giving access to other relevant data
