Field Details

SETUP_EXECUTION_CONTEXT

public static final Mode.Key<Boolean> SETUP_EXECUTION_CONTEXT

In some (rare) situations the ExecutionContext is not setup. The persist layer does not work without. This mode installs a new context and removes it after task execution.

L10N_CONTEXT

public static final Mode.Key<String> L10N_CONTEXT

L10N_LOCALE

public static final Mode.Key<Locale> L10N_LOCALE

COLLECTMODE

public static final Mode.Key<CollectMode> COLLECTMODE

When executing looping tasks (such as `expandTask()` for example), specify whether the results should be collected.

RATE_LIMITATION

public static final Mode.Key<Double> RATE_LIMITATION

Limit rate for looping tasks. The provided double number is equivalent to "permits per second".

CANCELLATION

public static final Mode.Key<Callable<Keys.Cancel>> CANCELLATION

Provide a cancellation function that is used in tasks that are combined with loops. The loop either throws an exception (Keys.Cancel.ERROR) or simply terminates (Keys.Cancel.STOP) depending on the result of the cancellation function. In case of Keys.Cancel.ERROR an CancellationException is thrown. The callable is expected to return a value and not throw. If it throws regardless, the exception is propagated.

OUTDATED_MAX_RETRIES

public static final Mode.Key<Integer> OUTDATED_MAX_RETRIES

Set max retries when OutdatedException occurs. Default is 0 retries.

NEW_CONTEXT

public static final Mode.Key<Boolean> NEW_CONTEXT

Create a new context for the task to be processed.
