		const SIM_ObjectArray &	objects,

		OP_EventType	reason,
		int	parm_index,
		OP_PropagateData &	prop_data
	)			`[protected, virtual]`

Override propagateModifiction because DOP nodes shouldn't propagate OP_INPUT_CHANGED events from their input nodes. Data doesn't flow through the network, so changes to one node don't necessarily indicate changes to the nodes it is connected to. Other input changed events should be handled normally as they may indicate changes to nodes referenced in expressions on this node.

Reimplemented from OP_Network.

virtual void DOP_Node::referencedParmChanged ( int pi ) [virtual]

Handle changes to a parameter that is referenced by one of our parameters. DOP Nodes want to treat this the same as a parm change.

		OP_Context &	,
		int
	)			`[protected, virtual]`

A DOP_Node has no data, so do nothing.

Implements OP_Node.

virtual int DOP_Node::saveCookedData	(	const char *	,
		OP_Context &
	)			`[protected, virtual]`

A DOP_Node has no data, so do nothing.

void DOP_Node::setCurrentObject	(	int	objectindex,
		int	objectcount,
		const SIM_Object *	object
	)

This functions sets the evaluation object index and the current object pointer that is used for local variable evaluation. It clears the current relationship information.

Examples:: DOP/DOP_GroupAndApply.C.

void DOP_Node::setCurrentRel ( const SIM_Relationship * rel )

This functions sets the evaluation relationship index and the current relationship pointer that is used for local variable evaluation. It clears the current object information.

virtual OP_ERROR DOP_Node::setInput	(	unsigned	idx,
		OP_Node *	op,
		unsigned	outputIdx = `0`
	)			`[virtual]`

Override the setInput functions so that we can send notification to the nodes that are our inputs when we disconnect from them. This lets then adjust their tile UI if necessary.

Reimplemented from OP_Node.

virtual OP_ERROR DOP_Node::setInputReference	(	unsigned	idx,
		const char *	label,
		int	keeppos,
		unsigned	outputIdx = `0`
