Classes

AcceptPendingException

Unchecked exception thrown when an attempt is made to initiate an accept operation on a channel and a previous accept operation has not completed.

AlreadyBoundException

Unchecked exception thrown when an attempt is made to bind the socket a network oriented channel that is already bound.

AlreadyConnectedException

Unchecked exception thrown when an attempt is made to connect a SocketChannel that is already connected.

AsynchronousChannelGroup

A grouping of asynchronous channels for the purpose of resource sharing.

AsynchronousCloseException

Checked exception received by a thread when another thread closes the channel or the part of the channel upon which it is blocked in an I/O operation.

AsynchronousFileChannel

An asynchronous channel for reading, writing, and manipulating a file.

AsynchronousServerSocketChannel

An asynchronous channel for stream-oriented listening sockets.

AsynchronousSocketChannel

An asynchronous channel for stream-oriented connecting sockets.

CancelledKeyException

Unchecked exception thrown when an attempt is made to use a selection key that is no longer valid.

Channels

Utility methods for channels and streams.

ClosedByInterruptException

Checked exception received by a thread when another thread interrupts it while it is blocked in an I/O operation upon a channel.

ClosedChannelException

Checked exception thrown when an attempt is made to invoke or complete an I/O operation upon channel that is closed, or at least closed to that operation.

ClosedSelectorException

Unchecked exception thrown when an attempt is made to invoke an I/O operation upon a closed selector.

ConnectionPendingException

Unchecked exception thrown when an attempt is made to connect a SocketChannel for which a non-blocking connection operation is already in progress.

DatagramChannel

A selectable channel for datagram-oriented sockets.

FileChannel

A channel for reading, writing, mapping, and manipulating a file.

FileChannel.MapMode

A typesafe enumeration for file-mapping modes.

FileLock

A token representing a lock on a region of a file.

FileLockInterruptionException

Checked exception received by a thread when another thread interrupts it while it is waiting to acquire a file lock.

IGatheringByteChannelExtensions
IllegalBlockingModeException

Unchecked exception thrown when a blocking-mode-specific operation is invoked upon a channel in the incorrect blocking mode.

IllegalChannelGroupException

Unchecked exception thrown when an attempt is made to open a channel in a group that was not created by the same provider.

IllegalSelectorException

Unchecked exception thrown when an attempt is made to register a channel with a selector that was not created by the provider that created the channel.

InterruptedByTimeoutException

Checked exception received by a thread when a timeout elapses before an asynchronous operation completes.

IReadableByteChannelExtensions
IScatteringByteChannelExtensions
IWritableByteChannelExtensions
MembershipKey

A token representing the membership of an Internet Protocol (IP) multicast group.

NoConnectionPendingException

Unchecked exception thrown when the SocketChannel#finishConnect finishConnect method of a SocketChannel is invoked without first successfully invoking its SocketChannel#connect connect method.

NonReadableChannelException

Unchecked exception thrown when an attempt is made to read from a channel that was not originally opened for reading.

NonWritableChannelException

Unchecked exception thrown when an attempt is made to write to a channel that was not originally opened for writing.

NotYetBoundException

Unchecked exception thrown when an attempt is made to invoke an I/O operation upon a server socket channel that is not yet bound.

NotYetConnectedException

Unchecked exception thrown when an attempt is made to invoke an I/O operation upon a socket channel that is not yet connected.

OverlappingFileLockException

Unchecked exception thrown when an attempt is made to acquire a lock on a region of a file that overlaps a region already locked by the same Java virtual machine, or when another thread is already waiting to lock an overlapping region of the same file.

Pipe

A pair of channels that implements a unidirectional pipe.

Pipe.SinkChannel

A channel representing the writable end of a Pipe.

Pipe.SourceChannel

A channel representing the readable end of a Pipe.

ReadPendingException

Unchecked exception thrown when an attempt is made to read from an asynchronous socket channel and a previous read has not completed.

SelectableChannel

A channel that can be multiplexed via a Selector.

SelectionKey

A token representing the registration of a SelectableChannel with a Selector.

Selector

A multiplexor of SelectableChannel objects.

ServerSocketChannel

A selectable channel for stream-oriented listening sockets.

ShutdownChannelGroupException

Unchecked exception thrown when an attempt is made to construct a channel in a group that is shutdown or the completion handler for an I/O operation cannot be invoked because the channel group has terminated.

SocketChannel

A selectable channel for stream-oriented connecting sockets.

UnresolvedAddressException

Unchecked exception thrown when an attempt is made to invoke a network operation upon an unresolved socket address.

UnsupportedAddressTypeException

Unchecked exception thrown when an attempt is made to bind or connect to a socket address of a type that is not supported.

WritePendingException

Unchecked exception thrown when an attempt is made to write to an asynchronous socket channel and a previous write has not completed.
