set_operator()

void MayaFlux::Nodes::Generator::Logic::set_operator	(	LogicOperator	op,
		bool	create_default_direct_function = false
	)

Sets the boolean operation to perform.

Parameters

op	Boolean operator to apply
create_default_direct_function	Whether to create a default direct function if none is set

Configures the node to use one of the standard boolean operations (AND, OR, XOR, etc.) for evaluating inputs.
