Package org.cpsolver.ifs.assignment.context

Assignment context can be used by a class (e.g., a constraint, a extension, a neighborhood selection, or a criterion) to contain any assignment dependent data.

Interface Summary

Interface	Description
AssignmentConstraintContext<V extends Variable<V,T>,T extends Value<V,T>>	An extension of the simple AssignmentContext which is used by the ConstraintWithContext class.
AssignmentContext	An interface marking an assignment context.
AssignmentContextHolder<V extends Variable<V,T>,T extends Value<V,T>>	An interface holding all assignment contexts associated with one assignment.
CanHoldContext	An additional interface that can be implemented by the HasAssignmentContext class.
CanInheritContext<V extends Variable<V,T>,T extends Value<V,T>,C extends AssignmentContext>	An additional interface that can be implemented by the HasAssignmentContext class.
HasAssignmentContext<V extends Variable<V,T>,T extends Value<V,T>,C extends AssignmentContext>	An interface to be implemented by a class that need an assignment context associated with it.

Class Summary

Class	Description
AbstractClassWithContext<V extends Variable<V,T>,T extends Value<V,T>,C extends AssignmentContext>	An abstract implementation of an assignment context holding class.
AssignmentContextHelper
AssignmentContextHolderArray<V extends Variable<V,T>,T extends Value<V,T>>	A simple assignment context holder implementation using array to store all the assignment contexts.
AssignmentContextHolderMap<V extends Variable<V,T>,T extends Value<V,T>>	A simple assignment context holder implementation using HashMap to store all the assignment contexts.
AssignmentContextReference<V extends Variable<V,T>,T extends Value<V,T>,C extends AssignmentContext>	A reference to an assignment context.
BinaryConstraintWithContext<V extends Variable<V,T>,T extends Value<V,T>,C extends AssignmentConstraintContext<V,T>>	A binary constraint with an assignment context.
ConstraintWithContext<V extends Variable<V,T>,T extends Value<V,T>,C extends AssignmentConstraintContext<V,T>>	A constraint with an assignment context.
DefaultParallelAssignmentContextHolder<V extends Variable<V,T>,T extends Value<V,T>>	A simple assignment context holder implementation used by the DefaultParallelAssignment class.
DefaultSingleAssignmentContextHolder<V extends Variable<V,T>,T extends Value<V,T>>	A simple assignment context holder implementation used by the DefaultSingleAssignment class.
ExtensionWithContext<V extends Variable<V,T>,T extends Value<V,T>,C extends AssignmentContext>	An extension with an assignment context.
InheritedAssignmentContextHolder<V extends Variable<V,T>,T extends Value<V,T>>	A variant of the AssignmentContextHolderMap that is used by the InheritedAssignment class.
InheritedAssignmentContextHolder.VersionedContext<U extends AssignmentContext>
ModelWithContext<V extends Variable<V,T>,T extends Value<V,T>,C extends AssignmentConstraintContext<V,T>>	A model with an assignment context.
NeighbourSelectionWithContext<V extends Variable<V,T>,T extends Value<V,T>,C extends AssignmentContext>	A neighborhood selection with an assignment context.
VariableWithContext<V extends Variable<V,T>,T extends Value<V,T>,C extends AssignmentContext>	A variable with an assignment context.

Enum Summary

Enum	Description
ModelWithContext.ContextUpdateType	Defines how the context of the model should be automatically updated (i.e., when AssignmentConstraintContext.assigned(Assignment, Value) and AssignmentConstraintContext.unassigned(Assignment, Value) are called).

Package org.cpsolver.ifs.assignment.context Description

Assignment context can be used by a class (e.g., a constraint, a extension, a neighborhood selection, or a criterion) to contain any assignment dependent data. Instead of holding the data directly, the class only holds a reference to the appropriate assignment context, which is stored with the assignment and returned from the assignment using the reference.
