org.apache.syncope.core.provisioning.java.propagation.AbstractPropagationTaskExecutor

org.apache.syncope.core.provisioning.java.propagation.PriorityPropagationTaskExecutor

All Implemented Interfaces:

PropagationTaskExecutor

public class PriorityPropagationTaskExecutor
extends AbstractPropagationTaskExecutor

Sorts the tasks to be executed according to related ExternalResource's priority, then execute. Tasks related to resources with NULL priority are executed after other tasks, concurrently. Failure during execution of a task related to resource with non-NULL priority are treated as fatal and will interrupt the whole process, resulting in a global failure.

newPropagationTaskCallable

protected PropagationTaskCallable newPropagationTaskCallable(PropagationTaskInfo taskInfo,
                                                             PropagationReporter reporter,
                                                             String executor)

Creates new instances of PropagationTaskCallable for usage with CompletionService.

Parameters:

taskInfo - to be executed

reporter - to report propagation execution status

executor - user that triggered the propagation execution

Returns:

new PropagationTaskCallable instance for usage with CompletionService

execute

public PropagationReporter execute(Collection<PropagationTaskInfo> taskInfos,
                                   boolean nullPriorityAsync,
                                   String executor)

Description copied from interface: PropagationTaskExecutor

Execute the given collection of tasks. The process is interrupted as soon as the result of the communication with a resource with non-null priority is in error.

Parameters:

taskInfos - to be execute, in given order

nullPriorityAsync - asynchronously executes tasks related to resources with no priority

executor - the executor of this task

Returns:

reporter to report propagation execution status
