Constructor Detail

SocketWrapperSocket

public SocketWrapperSocket(Identifier identifier,
                           P2PSocket<SubIdentifier> socket,
                           Logger logger,
                           java.util.Map<java.lang.String,java.lang.Integer> options)

Method Detail

getIdentifier

public Identifier getIdentifier()

Description copied from interface: P2PSocket

The identification of the node at the other end of the socket.

Specified by:

getIdentifier in interface P2PSocket<Identifier>

Returns:

The identification of the node at the other end of the socket.

close

public void close()

Description copied from interface: P2PSocket

Closes this socket.

Specified by:

close in interface P2PSocket<Identifier>

read

public long read(java.nio.ByteBuffer dsts)
          throws java.io.IOException

Description copied from interface: P2PSocket

Reads a sequence of bytes from this channel into a subsequence of the given buffer.

Specified by:

read in interface P2PSocket<Identifier>

Returns:

Throws:

java.io.IOException

read

public long read(java.nio.ByteBuffer[] dsts,
                 int offset,
                 int length)
          throws java.io.IOException

Description copied from interface: P2PSocket

Reads a sequence of bytes from this channel into a subsequence of the given buffers.

Specified by:

read in interface P2PSocket<Identifier>

Returns:

Throws:

java.io.IOException

register

public void register(boolean wantToRead,
                     boolean wantToWrite,
                     P2PSocketReceiver<Identifier> receiver)

Description copied from interface: P2PSocket

Must be called every time a Read/Write occurs to continue operation. Can cancel this task by calling with null.

Specified by:

register in interface P2PSocket<Identifier>

Parameters:

wantToRead - if you want to read from this socket

wantToWrite - if you want to write to this socket

receiver - will have receiveSelectResult() called on it note that you must call select() each time receiveSelectResult() is called. This is so your application can properly handle flow control

shutdownOutput

public void shutdownOutput()

Description copied from interface: P2PSocket

Disables the output stream for this socket. Used to properly close down a socket used for bi-directional communication that can be initated by either side.

Specified by:

shutdownOutput in interface P2PSocket<Identifier>

write

public long write(java.nio.ByteBuffer srcs)
           throws java.io.IOException

Description copied from interface: P2PSocket

Writes a sequence of bytes to this channel from a subsequence of the given buffers.

Specified by:

write in interface P2PSocket<Identifier>

Throws:

java.io.IOException

write

public long write(java.nio.ByteBuffer[] srcs,
                  int offset,
                  int length)
           throws java.io.IOException

Specified by:

write in interface P2PSocket<Identifier>

Throws:

java.io.IOException

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getOptions

public java.util.Map<java.lang.String,java.lang.Integer> getOptions()

Description copied from interface: P2PSocket

Details on the connectivity of the socket (encrypted, source-routed etc)

Specified by:

getOptions in interface P2PSocket<Identifier>

Returns:

a read-only list of options on this socket
