HandoffExecutorResolver

public abstract static class HandoffExecutorResolver.AbstractThreadFactoryResolver

resolveHandoffExecutor

public org.jboss.msc.service.ServiceName resolveHandoffExecutor(String handoffExecutorName,
                                                                String threadPoolName,
                                                                org.jboss.msc.service.ServiceName threadPoolServiceName,
                                                                org.jboss.msc.service.ServiceTarget serviceTarget)

Description copied from interface: HandoffExecutorResolver

Resolves the service name of the handoff executor a thread pool service should use, optionally providing a default executor in case the thread pool does not have a specifically configured handoff executor.

Specified by:

resolveHandoffExecutor in interface HandoffExecutorResolver

Parameters:

handoffExecutorName - the simple name of the handoff executor. Typically a reference value from the thread pool resource's configuration. Can be null in which case a default handoff executor may be returned.

threadPoolName - the name of the thread pool

threadPoolServiceName - the full name of the Service that provides the thread pool

serviceTarget - service target that is installing the thread pool service; can be used to install a ThreadFactoryService

Returns:

the ServiceName of the executor service the thread pool should use. May be {@link null}

releaseHandoffExecutor

public void releaseHandoffExecutor(String handoffExecutorName,
                                   String threadPoolName,
                                   org.jboss.msc.service.ServiceName threadPoolServiceName,
                                   OperationContext context)

Description copied from interface: HandoffExecutorResolver

Releases the handoff executor, doing any necessary cleanup, such as removing a default executor that was installed by HandoffExecutorResolver.resolveHandoffExecutor(String, String, org.jboss.msc.service.ServiceName, org.jboss.msc.service.ServiceTarget).

Specified by:

releaseHandoffExecutor in interface HandoffExecutorResolver

Parameters:

handoffExecutorName - the simple name of the thread factory. Typically a reference value from the thread pool resource's configuration. Can be null in which case a default thread factory should be released.

threadPoolName - the name of the thread pool

threadPoolServiceName - the full name of the Service that provides the thread pool

context - the context of the current operation; can be used to perform any necessary service removals

resolveNamedHandoffExecutor

protected abstract org.jboss.msc.service.ServiceName resolveNamedHandoffExecutor(String handoffExecutorName,
                                                                                 String threadPoolName,
                                                                                 org.jboss.msc.service.ServiceName threadPoolServiceName)

Create a service name to use for the thread factory in the case where a simple name for the factory was provided.

Parameters:

handoffExecutorName - the simple name of the thread factory. Will not be null

threadPoolName - the simple name of the related thread pool

threadPoolServiceName - the full service name of the thread pool

Returns:

the ServiceName of the ThreadFactoryService the thread pool should use. Cannot be null

releaseNamedHandoffExecutor

protected void releaseNamedHandoffExecutor(String handoffExecutorName,
                                           String threadPoolName,
                                           org.jboss.msc.service.ServiceName threadPoolServiceName,
                                           OperationContext context)

Handles the work of releaseHandoffExecutor(String, String, ServiceName, OperationContext) for the case where threadFactoryName is not null. This default implementation does nothing, assuming the thread factory is independently managed from the pool.

Parameters:

handoffExecutorName - the simple name of the thread factory. Will not be null

threadPoolName - the simple name of the related thread pool

threadPoolServiceName - the full service name of the thread pool

context - the context of the current operation; can be used to perform any necessary service removals

resolveDefaultHandoffExecutor

protected org.jboss.msc.service.ServiceName resolveDefaultHandoffExecutor(String threadPoolName,
                                                                          org.jboss.msc.service.ServiceName threadPoolServiceName,
                                                                          org.jboss.msc.service.ServiceTarget serviceTarget)

Optionally provides the service name of a default handoff executor. This implementation simply returns null, meaning there is no default.

Parameters:

threadPoolName - the name of the thread pool

threadPoolServiceName - the full name of the Service that provides the thread pool

serviceTarget - service target that is installing the thread pool service; can be used to install a ThreadFactoryService

Returns:

the ServiceName of the ThreadFactoryService the thread pool should use. May be null

releaseDefaultHandoffExecutor

protected void releaseDefaultHandoffExecutor(org.jboss.msc.service.ServiceName threadPoolServiceName,
                                             OperationContext context)

Removes any default thread factory installed in resolveDefaultHandoffExecutor(String, org.jboss.msc.service.ServiceName, org.jboss.msc.service.ServiceTarget). This default implementation does nothing, but any subclass that installs a default service should override this method to remove it.

Parameters:

threadPoolServiceName - the full name of the Service that provides the thread pool

context - the context of the current operation; can be used to perform any necessary service removals
