Constructor Detail

UnixSocketImpl

protected UnixSocketImpl()
                  throws java.io.IOException

Creates a new UnixSocketImpl

Method Detail

getFd

protected int getFd()

Gets the file descriptor for the socket.

Returns:

a file descriptor, or -1 if there is none

createSocket

protected static int createSocket()
                           throws java.io.IOException

Creates a native socket and returns its file descriptor.

Throws:

java.io.IOException - if an I/O error occurs when creating the socket.

bind

protected void bind(java.lang.String myPath)
             throws java.io.IOException

Binds to a path

Parameters:

myPath - path to bind to.

Throws:

java.io.IOException - if an I/O error occurs when binding.

listen

protected void listen(int backlog)
               throws java.io.IOException

Starts listening.

Parameters:

backlog - The maximum length of the queue

Throws:

java.io.IOException - if an I/O error occurs.

accept

protected UnixSocketImpl accept()
                         throws java.io.IOException

Listens for a connection to be made to this socket and accepts it. The method blocks until a connection is made.

Returns:

the new UnixSocketImpl

Throws:

java.io.IOException - if an I/O error occurs when waiting for a connection.

connect

protected void connect(java.lang.String path)
                throws java.io.IOException

Connects this socket to a path.

Throws:

If - there is a problem connecting the socket

close

protected void close()
              throws java.io.IOException

Closes this socket

Throws:

java.io.IOException - If there is a problem closing the socket

shutdownInput

protected void shutdownInput()
                      throws java.io.IOException

Disables the input stream for this socket.

Throws:

java.io.IOException - if an I/O error occurs when shutting down this socket.

shutdownOutput

protected void shutdownOutput()
                       throws java.io.IOException

Disables the output stream for this socket.

Throws:

java.io.IOException - if an I/O error occurs when shutting down this socket.

getInputStream

protected org.lirc.socket.UnixSocketInputStream getInputStream()
                                                        throws java.io.IOException

Returns an input stream for this socket. This method should only be called once for a socket.

Returns:

an input stream for reading bytes from this socket.

Throws:

java.io.IOException - if an I/O error occurs when creating the input stream.

getOutputStream

protected org.lirc.socket.UnixSocketOutputStream getOutputStream()
                                                          throws java.io.IOException

Returns an output stream for this socket. This method should only be called once for a socket.

Returns:

an output stream for writing bytes to this socket.

Throws:

java.io.IOException - if an I/O error occurs when creating the output stream.
