 SelectionKey key,
 int interest)
                  throws IOException

Throws:

IOException

deregisterKeyInterest

void deregisterKeyInterest(SelectorRunner selectorRunner,
 SelectionKey key,
 int interest)
                    throws IOException

 SelectableChannel channel,
 int interest,
 Object attachment)
              throws IOException

Throws:

IOException

 int interest,
 Object attachment,
 CompletionHandler<RegisterChannelResult> completionHandler)

deregisterChannel

void deregisterChannel(SelectorRunner selectorRunner,
 SelectableChannel channel)
                throws IOException

Deregister the channel from the SelectorRunner's Selector.

Parameters:

selectorRunner - SelectorRunner

channel - SelectableChannel channel to deregister

Throws:

IOException

deregisterChannelAsync

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

Deregister the channel from the SelectorRunner's Selector.

Parameters:

selectorRunner - SelectorRunner

channel - SelectableChannel channel to deregister

completionHandler - CompletionHandler

execute

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

Execute task in a selector thread. Unlike 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.

Parameters:

selectorRunner -

task -

completionHandler -

enque

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

Execute task in a selector thread. Unlike 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 select(org.glassfish.grizzly.nio.SelectorRunner) iteration.

Parameters:

selectorRunner -

task -

completionHandler -

onSelectorClosed

boolean onSelectorClosed(SelectorRunner selectorRunner)
