Detailed Description

template<typename GUM_SCALAR>
class gum::MultiDimDecorator< GUM_SCALAR >

Decorator design pattern in order to separate implementations from multidimensional matrix concepts.

A MultiDimDecorator is a virtual class for all encapsulation of MultiDimImplementation, for example probability, utility, etc. It implements a decorator design pattern in order to have a array, tree, sparse or matrix (...) implementation of MultiDimImplementation.

Template Parameters

GUM_SCALAR The type of the scalar stored in this multidimensional matrix.

◆ add()

template<typename GUM_SCALAR>

INLINE void gum::MultiDimDecorator< GUM_SCALAR >::add ( const DiscreteVariable & v )

finalvirtual

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

See also: operator<<(MultiDimInterface& c, const DiscreteVariable& v)

Warning: Note that the variable passed in argument is not duplicated, that is, only a pointer toward the variable is kept by the MultiDimInterface.

Parameters

v	The new var.

Exceptions

DuplicateElement	Raised if the variable already belongs to the sequence of variables.
OperationNotAllowed	Raised if this object is non mutable.
