Method Detail

getChannel

public Channel getChannel()

owner

public NioThread owner()

Description copied from interface: MigratablePipeline

Get NioThread currently owning this pipeline. Pipeline owner is a thread running this pipeline. IOBalancer can decide to migrate a pipeline to another owner.

Specified by:

owner in interface MigratablePipeline

Returns:

current owner

run

public final void run()

Specified by:

run in interface Runnable

onError

public void onError(Throwable cause)

Is called when the process() throws an exception. This method should only be called by the current owner. The idiom to use a handler is: try{ handler.handle(); } catch(Throwable t) { handler.onError(t); }

Parameters:

cause -

requestMigration

public final void requestMigration(NioThread newOwner)

Migrates this pipeline to a different owner. The migration logic is rather simple:

• Submit a de-registration task to a current NioThread
• The de-registration task submits a registration task to the new NioThread

Specified by:

requestMigration in interface MigratablePipeline

Parameters:

newOwner - target NioThread this handler migrates to
