Method Detail

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 interface Builtin

Overrides:

bodyCall in class BaseBuiltin

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 engines

context - 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
