callback_pair_exists()

bool MayaFlux::Nodes::callback_pair_exists	(	const std::vector< std::pair< NodeHook, NodeCondition > > &	callbacks,
		const NodeHook &	callback,
		const NodeCondition &	condition
	)

Checks if a specific callback and condition pair already exists.

Parameters

callbacks	The collection of conditional callbacks to search
callback	The callback function to look for
condition	The condition function to look for

Returns

True if the exact pair exists in the collection, false otherwise

This function checks if a specific combination of callback and condition functions is already registered. It's used to prevent duplicate registrations of the same callback-condition pair.
