Constructor Details

FlowImpl

public FlowImpl(FlowCompletion flowCompletion,
 EscalationCompletion escalationCompletion,
 ThreadState threadState)

Initiate.

Parameters:

flowCompletion - FlowCompletion of this Flow.

escalationCompletion - EscalationCompletion for this Flow.

threadState - ThreadState containing this Flow.

Method Details

getLinkedListSetOwner

public ThreadState getLinkedListSetOwner()

Description copied from interface: LinkedListSetEntry

Obtains the owner of the LinkedListSet that this LinkedListSetEntry may be added.

LinkedListSetEntry instances may only be added to the LinkedListSet they were intended for and can not be shared between LinkedListSet instances. This constraint:

1. ensures the integrity of the FunctionState, Flow, ThreadState, ProcessState structure, and
2. improves uniqueness performance as LinkedListSetEntry.getNext() and LinkedListSetEntry.getPrev() both returning null indicates not added

Specified by:

getLinkedListSetOwner in interface LinkedListSetEntry<Flow,ThreadState>

Returns:

Owner of the LinkedListSet that may contain this LinkedListSetEntry.

createFunction

public FunctionState createFunction(FunctionLogic logic)

Description copied from interface: Flow

Creates a FunctionState within this Flow for the FunctionLogic.

Specified by:

createFunction in interface Flow

Parameters:

logic - FunctionLogic.

Returns:

FunctionState for the FunctionLogic.

createManagedFunction

public <O extends Enum<O>,
F extends Enum<F>>
ManagedFunctionContainer createManagedFunction(Object parameter,
 ManagedFunctionMetaData<O,F> managedFunctionMetaData,
 boolean isEnforceGovernance,
 BlockState parallelFunctionOwner)

Description copied from interface: Flow

Creates a new managed ManagedFunctionContainer contained in this Flow for the ManagedFunction.

Specified by:

createManagedFunction in interface Flow

Type Parameters:

O - Dependency key type.

F - Flow key type.

Parameters:

parameter - Parameter for the ManagedFunction.

managedFunctionMetaData - ManagedFunctionMetaData for the new ManagedFunction.

isEnforceGovernance - true to enforce Governance on deactivation.

parallelFunctionOwner - BlockState that is the parallel owner of the new ManagedFunction.

Returns:

New ManagedFunctionContainer.

createGovernanceFunction

public <F extends Enum<F>> ManagedFunctionContainer createGovernanceFunction(GovernanceActivity<F> governanceActivity,
 GovernanceMetaData<?,F> governanceMetaData)

Description copied from interface: Flow

Creates a new ManagedFunctionContainer contained in this Flow for the GovernanceActivity.

Specified by:

createGovernanceFunction in interface Flow

Type Parameters:

F - Flow key type.

Parameters:

governanceActivity - GovernanceActivity.

governanceMetaData - GovernanceMetaData.

Returns:

New ManagedFunctionContainer.

createAdministrationFunction

public <E,
F extends Enum<F>,
G extends Enum<G>>
ManagedFunctionContainer createAdministrationFunction(ManagedObjectAdministrationMetaData<E,F,G> adminMetaData,
 ManagedFunctionContainer parallelFunctionOwner)

Description copied from interface: Flow

G - Governance key type.

Parameters:

adminMetaData - ManagedObjectAdministrationMetaData.

parallelFunctionOwner - ManagedFunctionContainer that is the parallel owner of the new ManagedFunction.

Returns:

New ManagedFunctionContainer.
