Throws:

java.io.IOException

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)
