Interface TimeConstraintBE

All Superinterfaces:

Externalizable, TimeConstraint

public interface TimeConstraintBE
extends TimeConstraint

Represents an extended backend analog of the front-end TimeConstraint interface, complemented with backend-related functionality for resolving the constraint limitations. These objects are created by the TimeConstraintProvider.resolve(TimeConstraint, com.prosyst.mprm.backend.rules.spi.time.SystemContext) method.

Method Summary

java.util.Date	getNextActivation(java.util.Date after) Returns the next activation time after a given point in time.
java.util.Date	getNextDeactivation(java.util.Date after) Returns the next deactivation time after a given point in time.
boolean	isActiveAt(java.util.Date date) Tests whether time Task activation is allowed at given time.

Method Detail

isActiveAt

boolean isActiveAt(java.util.Date date)

Tests whether time Task activation is allowed at given time.

Parameters:

date - time.

Returns:

true if Task activation is allowed at the supplied time, false otherwise.

getNextDeactivation

java.util.Date getNextDeactivation(java.util.Date after)

Returns the next deactivation time after a given point in time. If the TimeConstraint defines non-activeness at the specified time, then current time should be returned.

Parameters:

after - point in time after which deactivation time is requested.

Returns:

deactivation time.

getNextActivation

java.util.Date getNextActivation(java.util.Date after)

Returns the next activation time after a given point in time. If the TimeConstraint defines activeness at the specified time, then current time should be returned.

Parameters:

after - point in time after which activation time is requested.

Returns:

activation time.
