remove_hook()

bool MayaFlux::Nodes::Generator::Counter::remove_hook ( const NodeHook &  callback )

overridevirtual

Removes a previously registered callback.

Parameters

callback

The callback to remove

Returns

True if the callback was found and removed, false otherwise

Unregisters a callback that was previously registered with on_tick(). After removal, the callback will no longer be triggered when the node produces new output values.

This method is useful for cleaning up callbacks when they are no longer needed, preventing memory leaks and unnecessary processing.

Reimplemented from MayaFlux::Nodes::Node.
