Method Detail

register

public static void register(SharedTaskContext sharedTaskContext)

Initialize the SharedTaskContextHolder with the sharedTaskContext.

By registering the sharedTaskContext the strategy is made available for other code within the executing thread. This allows the guard task to abort the task being executed without knowing how.

The task itself is responsible to register a TaskAbortStrategy in the sharedTaskContext. This can be done by calling the setTaskAbortStrategy(TaskAbortStrategy).

As an example, see the HawaiiHttpComponentsClientHttpRequestFactory.

Parameters:

sharedTaskContext - the shared strategy to hold for the current thread.

remove

public static void remove()

Removes the current SharedTaskContext from the ThreadLocal store.

setTaskAbortStrategy

public static void setTaskAbortStrategy(TaskAbortStrategy taskAbortStrategy)

Set the current thread's taskAbortStrategy.

This sets the taskAbortStrategy into the thread's SharedTaskContext.

Parameters:

taskAbortStrategy - The strategy to set.

get

public static SharedTaskContext get()

Getter for #sharedTaskAbortStrategy.

Returns:

the shared task abort strategy

getTaskId

public static String getTaskId()

Return the task id for the current thread's task. It delegates to the thread local SharedTaskContext.getTaskId().

Returns:

The task's id.
