Methods

Modifier and Type	Method and Description
Set<IVariable<?>>	getAlwaysBound() Deprecated. Return the subset of the variables which are bound in all solutions.
Map<IVariable<?>,IConstant<?>>	getConstants() Deprecated. The set of variables which are effective constants (they are bound in every solution and always to the same value) together with their constant bindings.
Set<IVariable<?>>	getMaterialized() Deprecated. Return the subset of the variables which are materialized in all solutions in which they appear (the variables do not have to be bound in every solution, but if they are bound then their IVCache association is always set).
Set<IVariable<?>>	getNotAlwaysBound() Deprecated. Return the subset of the variables which are NOT bound in all solutions.
long	getSolutionSetSize() Deprecated. Return the #of solutions.
Set<IVariable<?>>	getUsedVars() Deprecated. Return the set of variables which in at least one solution.
