Class LifeCycleHelper

java.lang.Object
  wt.lifecycle.LifeCycleHelper

All Implemented Interfaces:

Externalizable, Serializable

public class LifeCycleHelper
extends Object
implements Externalizable

LifeCycleHelper provides client invokable methods to life cycle services. These methods are executed on the client side.

static String	ALL Transition initialization directive identifying all states in a sequence (life cycle).
static String	FIRST Transition initialization directive identifying the first state in a sequence (life cycle).
static String	LAST Transition initialization directive identifying the last state in a sequence (life cycle).

Method Summary

static boolean	isDeterministic(Transition transition) Returns true if the argrument transition is among those specified in the system configuration to be deterministic and false otherwise.
static boolean	isFinalPhase(wt.lifecycle.PhaseTemplate aPhaseTemplate) Answers whether the PhaseTemplate is a final phase Supported API: true
static wt.lifecycle.LifeCycleManaged	setLifeCycle(wt.lifecycle.LifeCycleManaged object, wt.lifecycle.LifeCycleTemplate lifeCycle) Set the LifeCycle of the LifeCycleManaged object and clear out the rest of the Life Cycle cookie.
static wt.lifecycle.LifeCycleManaged	setLifeCycle(wt.lifecycle.LifeCycleManaged object, wt.lifecycle.LifeCycleTemplateReference lctRef) Set the LifeCycle of the LifeCycleManaged object.

Method Detail

isFinalPhase

public static boolean isFinalPhase(wt.lifecycle.PhaseTemplate aPhaseTemplate)
                            throws WTException

Answers whether the PhaseTemplate is a final phase

Supported API: true

Parameters:

aPhaseTemplate - phase template that is being evaluated

Returns:

boolean

Throws:

WTException

setLifeCycle

public static wt.lifecycle.LifeCycleManaged setLifeCycle(wt.lifecycle.LifeCycleManaged object,
                                                         wt.lifecycle.LifeCycleTemplate lifeCycle)
                                                  throws wt.lifecycle.LifeCycleException,
                                                         WTPropertyVetoException

Set the LifeCycle of the LifeCycleManaged object and clear out the rest of the Life Cycle cookie. If the object is already persisted, this method will throw an exception.

Supported API: true

Parameters:

object - the LifeCycleManaged object whose life cycle will be set

lifeCycle - the LifeCycle to be set on the LifeCycleManaged object.

Returns:

LifeCycleManaged

Throws:

wt.lifecycle.LifeCycleException

WTPropertyVetoException

setLifeCycle

public static wt.lifecycle.LifeCycleManaged setLifeCycle(wt.lifecycle.LifeCycleManaged object,
                                                         wt.lifecycle.LifeCycleTemplateReference lctRef)
                                                  throws WTException,
                                                         wt.lifecycle.LifeCycleException,
                                                         WTPropertyVetoException

Set the LifeCycle of the LifeCycleManaged object. If the object is already persisted, this method will throw an exception.

Supported API: true

Parameters:

object - the LifeCycleManaged object whose life cycle should be set

lctRef - the LifeCycleReference of the LifeCycle that should be set on the LifeCycleManaged object.

Returns:

LifeCycleManaged

Throws:

WTException

wt.lifecycle.LifeCycleException

WTPropertyVetoException

isDeterministic

public static boolean isDeterministic(Transition transition)

Returns true if the argrument transition is among those specified in the system configuration to be deterministic and false otherwise. A transition is deterministic if it is permitted to be used at most once for a given source state.

Supported API: true

Parameters:

transition - the Transition whose configuration as deterministic is to be determined

Returns:

boolean
