authenticate

protected void authenticate(OutputStream _out,
                            InputStream _in,
                            Socket _sock)

Helper method to authenticate to DBus using SASL.

Parameters:

_out - output stream

_in - input stream

_sock - socket

Throws:

IOException - on any error

setInputOutput

protected void setInputOutput(Socket _socket)

Setup message reader/writer. Will look for SPI provider first, if none is found default implementation is used. The default implementation does not support file descriptor passing!

Parameters:

_socket - socket to use

getSaslAuthMode

protected int getSaslAuthMode()

setSaslAuthMode

protected void setSaslAuthMode(int _saslAuthMode)

getSaslMode

protected SASL.SaslMode getSaslMode()

setSaslMode

protected void setSaslMode(SASL.SaslMode _saslMode)

getAddress

protected BusAddress getAddress()

getLogger

protected org.slf4j.Logger getLogger()

close

public void close()
           throws IOException

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Throws:
