Method Detail

getProcessIdentifier

public java.lang.Object getProcessIdentifier()

Description copied from interface: ProcessState

Obtains the identifier for this ProcessState.

Specified by:

getProcessIdentifier in interface ProcessState

Returns:

Identifier for this ProcessState.

getProcessManager

public ProcessManager getProcessManager()

Description copied from interface: ProcessState

Obtains the ProcessManager for this ProcessState.

Specified by:

getProcessManager in interface ProcessState

Returns:

ProcessManager for this ProcessState.

isCancelled

public boolean isCancelled()

Description copied from interface: ProcessState

Indicates if the ProcessState has been cancelled.

This is only valid after synchronising with this ProcessState (in other words the main ThreadState).

Specified by:

isCancelled in interface ProcessState

Returns:

true if cancelled - or indeterminate if have not synchronised on ProcessState.

getMainThreadState

public ThreadState getMainThreadState()

Description copied from interface: ProcessState

Obtains the main ThreadState for this ProcessState.

The main ThreadState is used for any ProcessState mutations. This avoids the possibility of data corruption, as only one ThreadState may alter the ProcessState.

Specified by:

getMainThreadState in interface ProcessState

Returns:

Main ThreadState for this ProcessState.

getManagedObjectCleanup

public ManagedObjectCleanup getManagedObjectCleanup()

Description copied from interface: ProcessState

Obtains the ManagedObjectCleanup for this ProcessState.

Specified by:

getManagedObjectCleanup in interface ProcessState

Returns:

ManagedObjectCleanup for this ProcessState.

spawnThreadState

public FunctionState spawnThreadState(ManagedFunctionMetaData<?,?> managedFunctionMetaData,
                                      java.lang.Object parameter,
                                      FlowCompletion completion,
                                      boolean isEscalationHandlingThreadState)

Description copied from interface: ProcessState

Spawns a new ThreadState contained in this ProcessState.

Specified by:

spawnThreadState in interface ProcessState

Parameters:

managedFunctionMetaData - ManagedFunctionMetaData of the initial ManagedFunction within the spawned ThreadState.

parameter - Parameter for the initial ManagedFunction.

completion - Optional FlowCompletion to be notified of completion of the spawned ThreadState.

isEscalationHandlingThreadState - Indicates whether the ThreadState is for Escalation handling.

Returns:

FunctionState to spawn the ThreadState.

threadComplete

public FunctionState threadComplete(ThreadState thread,
                                    FunctionState threadCompletion)

Description copied from interface: ProcessState

Flags that the input ThreadState has complete.

Specified by:

threadComplete in interface ProcessState

Parameters:

thread - ThreadState that has completed.

threadCompletion - Optional FunctionState for the completion of theThreadState. May be null.

Returns:

FunctionState to complete the ThreadState.

getManagedObjectContainer

public ManagedObjectContainer getManagedObjectContainer(int index)

Description copied from interface: ProcessState

Obtains the ManagedObjectContainer for the input index.

Specified by:

getManagedObjectContainer in interface ProcessState

Parameters:

index - Index of the ManagedObjectContainer to be returned.

Returns:

ManagedObjectContainer for the index.

getFunctionLoop

public FunctionLoop getFunctionLoop()

Description copied from interface: ProcessState

Obtains the FunctionLoop for the ProcessState.

Specified by:

getFunctionLoop in interface ProcessState

Returns:

FunctionLoop for the ProcessState.
