  • Interface Summary
    Interface Description
    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.
  • Class Summary
    Class Description
    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, forming a unidirectional pipe.
    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.
  • Exception Summary
    Exception Description
    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 SocketChannel.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.
