Interface NetworkChannel
- All Superinterfaces:
- AutoCloseable,- Channel,- Closeable
- All Known Subinterfaces:
- MulticastChannel
- All Known Implementing Classes:
- AsynchronousServerSocketChannel,- AsynchronousSocketChannel,- DatagramChannel,- ServerSocketChannel,- SocketChannel
 A channel that implements this interface is a channel to a network
 socket. The bind method is used to bind the
 socket to a local address, the getLocalAddress method returns the address that the socket is bound to, and
 the setOption and getOption methods are used to set and query socket
 options.  An implementation of this interface should specify the socket options
 that it supports.
 
 The bind and setOption methods that do
 not otherwise have a value to return are specified to return the network
 channel upon which they are invoked. This allows method invocations to be
 chained. Implementations of this interface should specialize the return type
 so that method invocations on the implementation class can be chained.

Method Details- 
bindBinds the channel's socket to a local address.This method is used to establish an association between the socket and a local address. Once an association is established then the socket remains bound until the channel is closed. If the localparameter has the valuenullthen the socket will be bound to an address that is assigned automatically.- Parameters:
- local- The address to bind the socket, or- nullto bind the socket to an automatically assigned socket address
- Returns:
- This channel
- Throws:
- AlreadyBoundException- If the socket is already bound
- UnsupportedAddressTypeException- If the type of the given address is not supported
- ClosedChannelException- If the channel is closed
- IOException- If some other I/O error occurs
- See Also:
 
- 
getLocalAddressReturns the socket address that this channel's socket is bound to.Where the channel is boundto an Internet Protocol socket address then the return value from this method is of typeInetSocketAddress.- Returns:
- The socket address that the socket is bound to, or nullif the channel's socket is not bound
- Throws:
- ClosedChannelException- If the channel is closed
- IOException- If an I/O error occurs
 
- 
setOptionSets the value of a socket option.- Type Parameters:
- T- The type of the socket option value
- Parameters:
- name- The socket option
- value- The value of the socket option. A value of- nullmay be a valid value for some socket options.
- Returns:
- This channel
- Throws:
- UnsupportedOperationException- If the socket option is not supported by this channel
- IllegalArgumentException- If the value is not a valid value for this socket option
- ClosedChannelException- If this channel is closed
- IOException- If an I/O error occurs
- See Also:
 
- 
getOptionReturns the value of a socket option.- Type Parameters:
- T- The type of the socket option value
- Parameters:
- name- The socket option
- Returns:
- The value of the socket option. A value of nullmay be a valid value for some socket options.
- Throws:
- UnsupportedOperationException- If the socket option is not supported by this channel
- ClosedChannelException- If this channel is closed
- IOException- If an I/O error occurs
- See Also:
 
- 
supportedOptionsSet<SocketOption<?>> supportedOptions()Returns a set of the socket options supported by this channel.This method will continue to return the set of options even after the channel has been closed. - Returns:
- A set of the socket options supported by this channel
