Class InheritedAssignmentContextHolder<V extends Variable<V,T>,T extends Value<V,T>>

java.lang.Object

org.cpsolver.ifs.assignment.context.AssignmentContextHolderMap<V,T>

org.cpsolver.ifs.assignment.context.DefaultParallelAssignmentContextHolder<V,T>

org.cpsolver.ifs.assignment.context.InheritedAssignmentContextHolder<V,T>

Type Parameters:

V - Variable

T - Value

All Implemented Interfaces:

AssignmentContextHolder<V,T>

public class InheritedAssignmentContextHolder<V extends Variable<V,T>,T extends Value<V,T>>
extends DefaultParallelAssignmentContextHolder<V,T>

A variant of the AssignmentContextHolderMap that is used by the InheritedAssignment class. If a HasAssignmentContext class implements the CanInheritContext interface, this class will use the CanInheritContext.inheritAssignmentContext(Assignment, AssignmentContext) method instead of the HasAssignmentContext.createAssignmentContext(Assignment) method to create a new context.
