Friends And Related Function Documentation

◆ operator==()

bool operator==	(	const DiscreteFunctionSpaceInterface< Traits > &	X,
		const DiscreteFunctionSpaceInterface< Traits > &	Y
	)

This is a default implemented equality operator for discrete function spaces. It assumes the mapper to be a singleton and then compares the addresses of the two mappers.

Note that this method can be specialized by implementing another version that uses the exact traits of the discrete function space.
