Field Detail

### OPTIONS

    public static final java.util.Map<java.lang.String,java.lang.Integer> OPTIONS

### MAX_OPEN_SOCKETS

    public final int MAX_OPEN_SOCKETS

### SOCKET_BUFFER_SIZE

    public final int SOCKET_BUFFER_SIZE

Constructor Detail

### TCPLayer

    public TCPLayer(WireTransportLayerImpl wire)
             throws java.io.IOException

  Which socket to collect.

  Throws:
    `java.io.IOException`

Method Detail

### openSocket

    public SocketRequestHandle<java.net.InetSocketAddress> openSocket(java.net.InetSocketAddress destination,
                                                                      SocketCallback<java.net.InetSocketAddress> deliverSocketToMe,
                                                                      java.util.Map<java.lang.String,java.lang.Integer> options)

### destroy

    public void destroy()

  Method which cloeses a socket to a given remote node handle, and updates the bookkeeping to keep track of this closing. Note that this method does not completely close the socket, rather, it simply calls shutdown(), which starts the shutdown process.

  Parameters:
    `address` - The address of the remote node

### acceptSockets

    public void acceptSockets(boolean b)

### accept

    public void accept(java.nio.channels.SelectionKey key)

  Specified by the SelectionKeyHandler interface. Is called whenever a key has become acceptable, representing an incoming connection. This method will accept the connection, and attach a SocketConnector in order to read the greeting off of the channel. Once the greeting has been read, the connector will hand the channel off to the appropriate node handle.

  Overrides:
    `accept` in class `SelectionKeyHandler`
  Parameters:
    `key` - The key which is acceptable.
