Method Summary

Modifier and Type	Method and Description
pack-priv static void	bindToGroup(AsynchronousChannelGroupImpl group) Binds this thread to the given group
pack-priv static Invoker.GroupAndInvokeCount	getGroupAndInvokeCount() Returns the GroupAndInvokeCount object for this thread.
pack-priv static <V, A> void	invoke(AsynchronousChannel channel, CompletionHandler<V, ? super A> handler, A attachment, V result, Throwable exc) Invokes the handler.
pack-priv static <V, A> void	invoke(PendingFuture<V, A> future) Invoke handler with completed result.
pack-priv static <V, A> void	invokeDirect(Invoker.GroupAndInvokeCount myGroupAndInvokeCount, CompletionHandler<V, ? super A> handler, A attachment, V result, Throwable exc) Invoke handler assuming thread identity already checked
pack-priv static <V, A> void	invokeIndirectly(AsynchronousChannel channel, final CompletionHandler<V, ? super A> handler, final A attachment, final V result, final Throwable exc) Invokes the handler indirectly via the channel group's thread pool.
pack-priv static <V, A> void	invokeIndirectly(final CompletionHandler<V, ? super A> handler, final A attachment, final V value, final Throwable exc, Executor executor) Invokes the handler "indirectly" in the given Executor
pack-priv static <V, A> void	invokeIndirectly(PendingFuture<V, A> future) Invoke handler with completed result.
pack-priv static void	invokeOnThreadInThreadPool(Groupable channel, Runnable task) Invokes the given task on the thread pool associated with the given channel.
pack-priv static <V, A> void	invokeUnchecked(CompletionHandler<V, ? super A> handler, A attachment, V value, Throwable exc) Invoke handler without checking the thread identity or number of handlers on the thread stack.
pack-priv static <V, A> void	invokeUnchecked(PendingFuture<V, A> future) Invoke handler with completed result.
pack-priv static boolean	isBoundToAnyGroup() Returns true if the current thread is in a channel group's thread pool
pack-priv static boolean	mayInvokeDirect(Invoker.GroupAndInvokeCount myGroupAndInvokeCount, AsynchronousChannelGroupImpl group) Returns true if the current thread is in the given channel's thread pool and we haven't exceeded the maximum number of handler frames on the stack.

Method Detail

bindToGroup	back to summary
pack-priv static void bindToGroup(AsynchronousChannelGroupImpl group) Binds this thread to the given group

getGroupAndInvokeCount	back to summary
pack-priv static Invoker.GroupAndInvokeCount getGroupAndInvokeCount() Returns the GroupAndInvokeCount object for this thread.

invoke	back to summary
pack-priv static <V, A> void invoke(AsynchronousChannel channel, CompletionHandler<V, ? super A> handler, A attachment, V result, Throwable exc) Invokes the handler. If the current thread is in the channel group's thread pool then the handler is invoked directly, otherwise it is invoked indirectly.

invoke	back to summary
pack-priv static <V, A> void invoke(PendingFuture<V, A> future) Invoke handler with completed result. If the current thread is in the channel group's thread pool then the handler is invoked directly, otherwise it is invoked indirectly.

invokeDirect	back to summary
pack-priv static <V, A> void invokeDirect(Invoker.GroupAndInvokeCount myGroupAndInvokeCount, CompletionHandler<V, ? super A> handler, A attachment, V result, Throwable exc) Invoke handler assuming thread identity already checked

invokeIndirectly	back to summary
pack-priv static <V, A> void invokeIndirectly(AsynchronousChannel channel, final CompletionHandler<V, ? super A> handler, final A attachment, final V result, final Throwable exc) Invokes the handler indirectly via the channel group's thread pool.

invokeIndirectly	back to summary
pack-priv static <V, A> void invokeIndirectly(final CompletionHandler<V, ? super A> handler, final A attachment, final V value, final Throwable exc, Executor executor) Invokes the handler "indirectly" in the given Executor

invokeIndirectly	back to summary
pack-priv static <V, A> void invokeIndirectly(PendingFuture<V, A> future) Invoke handler with completed result. The handler is invoked indirectly, via the channel group's thread pool.

invokeOnThreadInThreadPool	back to summary
pack-priv static void invokeOnThreadInThreadPool(Groupable channel, Runnable task) Invokes the given task on the thread pool associated with the given channel. If the current thread is in the thread pool then the task is invoked directly.

invokeUnchecked	back to summary
pack-priv static <V, A> void invokeUnchecked(CompletionHandler<V, ? super A> handler, A attachment, V value, Throwable exc) Invoke handler without checking the thread identity or number of handlers on the thread stack.

invokeUnchecked	back to summary
pack-priv static <V, A> void invokeUnchecked(PendingFuture<V, A> future) Invoke handler with completed result. This method does not check the thread identity or the number of handlers on the thread stack.

isBoundToAnyGroup	back to summary
pack-priv static boolean isBoundToAnyGroup() Returns true if the current thread is in a channel group's thread pool

mayInvokeDirect	back to summary
pack-priv static boolean mayInvokeDirect(Invoker.GroupAndInvokeCount myGroupAndInvokeCount, AsynchronousChannelGroupImpl group) Returns true if the current thread is in the given channel's thread pool and we haven't exceeded the maximum number of handler frames on the stack.
