Adds a new var to the variables of the multidimensional matrix.

◆ replace()

INLINE void gum::MultiDimInterface::replace	(	const DiscreteVariable &	x,
		const DiscreteVariable &	y
	)

inherited

Replace variables in this multidim.

If x is in this MultiDim and y has the same domain size, then x will be replace by y in this MultiDim.

Parameters

x	The variable in this which will be replaced.
y	The variable replacing y.

Exceptions

NotFound	Raised if x does not belong to this MultiDim.
OperationNotAllowed	If y and x are not interchangeable.
DuplicateElement	If y is already in this MultiDim.
