Method Detail

createOperation

public <T extends Annotation> OperationHandle<T> createOperation(T scope)

Description copied from interface: OperationManager

Creates an OperationHandle. The returned handle will not be associated with any threads. The scope parameter is normally created with AnnotationLiteral

Specified by:

createOperation in interface OperationManager

Parameters:

scope - The scope annotation for this operation type

Returns:

A non-null OperationHandle that can be used to associate threads with the Operation

createAndStartOperation

public <T extends Annotation> OperationHandle<T> createAndStartOperation(T scope)

Description copied from interface: OperationManager

Creates an OperationHandle that will be associated with the thread calling this method. The scope parameter is normally created with AnnotationLiteral

Specified by:

createAndStartOperation in interface OperationManager

Parameters:

scope - The scope annotation for this operation type

Returns:

A non-null OperationHandle that can be used to associate threads with the Operation

getCurrentOperations

public <T extends Annotation> Set<OperationHandle<T>> getCurrentOperations(T scope)

Description copied from interface: OperationManager

Gets a set of all Operations that are in state OperationState.ACTIVE or OperationState.SUSPENDED. Operations that are in the OperationState.CLOSED state are no longer tracked by the Manager. The scope parameter is normally created with AnnotationLiteral

Specified by:

getCurrentOperations in interface OperationManager

Parameters:

scope - The scope annotation for this operation type

Returns:

A non-null but possibly empty set of OperationHandles that have not been closed

getCurrentOperation

public <T extends Annotation> OperationHandle<T> getCurrentOperation(T scope)

Description copied from interface: OperationManager

Gets the current operation of scope type on the current thread. The scope parameter is normally created with AnnotationLiteral

Specified by:

getCurrentOperation in interface OperationManager

Parameters:

scope - The scope annotation for this operation type

Returns:

The current operation of the given type on this thread. May be null if there is no active operation on this thread of this type

shutdownAllOperations

public void shutdownAllOperations(Annotation scope)

Description copied from interface: OperationManager

This method will suspend all currently open operations on all threads and then close them. This will also remove all entities associated with this operation type, including the OperationHandle associated with this scope from the HK2 locator service registry. Therefore this mechanism of shutting down the operations should be used with care, and would normally only be used when the Operation type can never be used again.

The scope parameter is normally created with AnnotationLiteral

Specified by:

shutdownAllOperations in interface OperationManager

Parameters:

scope - The scope annotation for this operation type
