safe_add_conditional_callback()

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

Safely adds a conditional callback if it doesn't already exist.

Parameters

callbacks	The collection of conditional callbacks to add to
callback	The callback function to add
condition	The condition function to add

Returns

True if the conditional callback was added, false if it already existed

This function first checks if the exact callback-condition pair already exists in the collection, and only adds it if it's not already present. This prevents duplicate registrations of the same conditional callback.
