This method returns a constraint that states that whenever
interval variable a is present, it cannot contain a
value t such that f(t)=0.
Namespace: ILOG.CP
Assembly: oplall (in oplall.dll)

public IConstraint ForbidExtent( IIntervalVar a, INumToNumStepFunction f ) |
Remarks
You must add this constraint to a model and extract the model for an algorithm in order for it to be taken into account.
Typically, this constraint can be used in combination with an intensity function to state that the interval variable cannot overlap intervals where its intensity function is nul.
For more information on interval variables,see the Concepts section of the C++ API Reference Manual.
Note: This constraint cannot be used in a logical constraint.
