                       throws IOException

Description copied from interface: SelectorHandler

Deregister the channel from the SelectorRunner's Selector.

Specified by:

deregisterChannel in interface SelectorHandler

Parameters:

selectorRunner - SelectorRunner

channel - SelectableChannel channel to deregister

Throws:

IOException

deregisterChannelAsync

public void deregisterChannelAsync(SelectorRunner selectorRunner,
                                   SelectableChannel channel,
                                   CompletionHandler<RegisterChannelResult> completionHandler)

Description copied from interface: SelectorHandler

Deregister the channel from the SelectorRunner's Selector.

Specified by:

deregisterChannelAsync in interface SelectorHandler

Parameters:

selectorRunner - SelectorRunner

channel - SelectableChannel channel to deregister

completionHandler - CompletionHandler

execute

public void execute(SelectorRunner selectorRunner,
                    SelectorHandler.Task task,
                    CompletionHandler<SelectorHandler.Task> completionHandler)

Description copied from interface: SelectorHandler

Execute task in a selector thread. Unlike SelectorHandler.enque(org.glassfish.grizzly.nio.SelectorRunner, org.glassfish.grizzly.nio.SelectorHandler.Task, org.glassfish.grizzly.CompletionHandler), this operation will execute the task immediately if the current is a selector thread.

Specified by:

execute in interface SelectorHandler

enque

public void enque(SelectorRunner selectorRunner,
                  SelectorHandler.Task task,
                  CompletionHandler<SelectorHandler.Task> completionHandler)

Description copied from interface: SelectorHandler

Execute task in a selector thread. Unlike SelectorHandler.execute(org.glassfish.grizzly.nio.SelectorRunner, org.glassfish.grizzly.nio.SelectorHandler.Task, org.glassfish.grizzly.CompletionHandler), this operation will postpone the task execution if current thread is a selector thread, and execute it during the next SelectorHandler.select(org.glassfish.grizzly.nio.SelectorRunner) iteration.

Specified by:

enque in interface SelectorHandler

onSelectorClosed

public boolean onSelectorClosed(SelectorRunner selectorRunner)

Specified by:

onSelectorClosed in interface SelectorHandler
