◆ _get()

template<typename GUM_SCALAR >

INLINE GUM_SCALAR & gum::MultiDimArray< GUM_SCALAR >::_get ( const Instantiation & i ) const

Return a data, given a Instantiation.

Note that get allows to change a value in the container. The method is tagged as const since a multidim is not const if its dimension changed.

Warning: If i variables set is disjoint with this MultiDimContainer then 0 is assumed for dimensions (i.e. variables) not present in the instantiation.

Parameters

i	The instantiation used to find the data.

Compute the offset of a Instantiation.

If the instantiation is not fully compatible with the MultiDimWithOffset, no exception thrown but 0 is assumed for dimensions not present in the instantiation.

for instance : M<<a<<b<<c; with i=b:1|c:2|d:1 then M._getOffs(i) give the offset of a:0|b:1|c:2.

Parameters

i	An instantiation for which the offset is computed.

Returns: The offset of i.

for instance : M<<a<<b<<c; with i=b:1|c:2|d:1 then M._getOffs(i) give the offset of a:0|b:1|c:2.

This method uses domainSize() and realSize() to compute the ration, both methods are virtual and should be surcharge if a subclass has a special policies about memory management.

Warning: This compression ratio is not exactly the memory compression ratio. It is computed in terms of number of parameters.

Returns: Returns the compression ration of the table.

This thus corresponds to the internal MultiDimArray's offset we would get by using function get with instantiation {x1,...,xk}.

offset The offset of the returned value. Returns the element stored in the multidimArray at a given offset.

◆ setByOffset()

INLINE void gum::MultiDimArray< GUM_SCALAR >::setByOffset	(	Idx	offset,

Modifies the element stored in the multidimArray at a given offset.

The offset is computed as follows: let S={X1,...,Xk} be the sequence of variables in the multidim, and let x1,...,xk be their values respectively. then the corresponding offset is x1 + |X1| * x2 + [X1| * |X2| * x3 + ...

offset	The offset where to store the value.

◆ _gaps

template<typename GUM_SCALAR>

HashTable< const DiscreteVariable*, Size > gum::MultiDimWithOffset< GUM_SCALAR >::_gaps

protectedinherited

The gaps between consecutive values of a given variable.

For each variable, we keep track of the interval between two consecutive values of the variable in vector values. Thus, shifting from one value to the next one is equivalent to incrementing/decrementing by gaps the current offset w.r.t. vector values.
