Interface NetworkChannel

    • Method Detail

      • bind

        NetworkChannel bind​(SocketAddress local)
                     throws IOException
        Binds 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 local parameter has the value null then the socket will be bound to an address that is assigned automatically.

        local - The address to bind the socket, or null to bind the socket to an automatically assigned socket address
        This channel
        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
        SecurityException - If a security manager is installed and it denies an unspecified permission. An implementation of this interface should specify any required permissions.

      • supportedOptions

        Set<SocketOption<?>> supportedOptions()
