Channels provide a way to connect to sources of data such as files, sockets or other structures that allow input and/or output of data.
ByteChannel | A ByteChannel is both readable and writable. |
Channel | A channel is a conduit to I/O services covering such items as files, sockets, hardware devices, I/O ports or some software component. |
GatheringByteChannel | The interface for channels that can write a set of buffers in a single operation. |
InterruptibleChannel | Channels that implement this interface can be asynchronously closed and interrupted. |
ReadableByteChannel | A ReadableByteChannel is a type of Channel that can read
bytes. |
ScatteringByteChannel | The interface for channels that can read data into a set of buffers in a single operation. |
WritableByteChannel | A WritableByteChannel is a type of Channel that can write
bytes. |
Channels | This class provides several utilities to get I/O streams from channels. |
DatagramChannel | A DatagramChannel is a selectable channel that represents a partial
abstraction of a datagram socket. |
FileChannel | An abstract channel type for interaction with a platform file. |
FileChannel.MapMode | MapMode defines file mapping mode constants. |
FileLock | A FileLock represents a locked region of a file. |
Pipe | A pipe contains two channels. |
Pipe.SinkChannel | Writable sink channel used to write to a pipe. |
Pipe.SourceChannel | Readable source channel used to read from a pipe. |
SelectableChannel | A channel that can be used with a Selector . |
SelectionKey | A SelectionKey represents the relationship between a channel and a
selector for which the channel is registered. |
Selector | A controller for the selection of SelectableChannel objects. |
ServerSocketChannel | A ServerSocketChannel is a partial abstraction of a selectable,
stream-oriented listening socket. |
SocketChannel | A SocketChannel is a selectable channel that provides a partial
abstraction of stream connecting socket. |
AlreadyConnectedException | An AlreadyConnectedException is thrown when an attempt is made to
connect a SocketChannel that is already connected. |
AsynchronousCloseException | An AsynchronousCloseException is thrown when the underlying channel
for an I/O operation is closed by another thread. |
CancelledKeyException | A CancelledKeyException is thrown when an invalid selection key is
used. |
ClosedByInterruptException | A ClosedByInterruptException is thrown when a thread is interrupted
in a blocking I/O operation. |
ClosedChannelException | A ClosedChannelException is thrown when a channel is closed for the
type of operation attempted. |
ClosedSelectorException | A ClosedSelectorException is thrown when a selector
is closed and an I/O operation is attempted. |
ConnectionPendingException | A ConnectionPendingException is thrown when an attempt is made to
connect a SocketChannel that has a non-blocking connection already
underway. |
FileLockInterruptionException | A FileLockInterruptionException is thrown when a thread is
interrupted while waiting to acquire a file lock. |
IllegalBlockingModeException | An IllegalBlockingModeException is thrown when an operation that
requires a specific blocking mode is invoked on a channel that is in a
different blocking mode. |
IllegalSelectorException | An IllegalSelectorException is thrown when a call is made to register
a channel on a selector that has been created by a different provider. |
NoConnectionPendingException | A NoConnectionPendingException is thrown if SocketChannel 's
finishConnect method is called before
the SocketChannel 's connect(java.net.SocketAddress) connect} method completed
without error. |
NonReadableChannelException | A NonReadableChannelException is thrown when attempting to read from
a channel that is not open for reading. |
NonWritableChannelException | A NonWritableChannelException is thrown when attempting to write to a
channel that is not open for writing. |
NotYetBoundException | A NotYetBoundException is thrown if the server socket channel is not
bound before an I/O operation is made. |
NotYetConnectedException | A NotYetConnectedException is thrown if the socket channel is not
connected before an I/O operation is invoked. |
OverlappingFileLockException | An OverlappingFileLockException is thrown when attempting to acquire
a lock that overlaps an existing or pending lock held by this process. |
UnresolvedAddressException | An UnresolvedAddressException is thrown when trying to use an
unresolved network address in a network operation. |
UnsupportedAddressTypeException | An UnsupportedAddressTypeException is thrown when connecting or
binding to an unsupported address type. |
