Method Detail

decorate

public final java.io.InputStream decorate(java.net.Socket socket,
                                          java.io.InputStream stream)
                                   throws java.io.IOException

Creates a decorated InputStream.

Specified by:

decorate in interface SocketStreamDecorationStrategy

Parameters:

socket - the source of the original stream

stream - the stream to be decorated

Returns:

a decorated InputStream.

Throws:

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

decorate

public final java.io.OutputStream decorate(java.net.Socket socket,
                                           java.io.OutputStream stream)
                                    throws java.io.IOException

Creates a decorated OutputStream.

Specified by:

decorate in interface SocketStreamDecorationStrategy

Parameters:

socket - the source of the original stream

stream - the stream to be decorated

Returns:

a decorated OutputStream.

Throws:

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

uncheckedDecorate

protected java.io.InputStream uncheckedDecorate(java.net.Socket socket,
                                                java.io.InputStream stream)
                                         throws java.io.IOException

Creates a decorated InputStream.

Parameters:

socket - the source of the original stream

stream - the stream to be decorated

Returns:

a decorated InputStream.

Throws:

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

uncheckedDecorate

protected java.io.OutputStream uncheckedDecorate(java.net.Socket socket,
                                                 java.io.OutputStream stream)
                                          throws java.io.IOException

Creates a decorated OutputStream.

Parameters:

socket - the source of the original stream

stream - the stream to be decorated

Returns:

a decorated OutputStream.

Throws:

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

closeStream

protected void closeStream(java.io.InputStream stream)

Closes the stream. If an exception is thrown while closing the stream the exceptionDuringStreamClose is called.

Parameters:

stream - the stream to be closed

closeStream

protected void closeStream(java.io.OutputStream stream)

Closes the stream. If an exception is thrown while closing the stream the exceptionDuringStreamClose is called.

Parameters:

stream - the stream to be closed

exceptionDuringStreamClose

protected void exceptionDuringStreamClose(java.io.InputStream stream,
                                          java.lang.Exception e)

Called when an exception is thrown during a call to closeStream.

Parameters:

stream - the stream the threw the exception

e - the exception thrown

exceptionDuringStreamClose

protected void exceptionDuringStreamClose(java.io.OutputStream stream,
                                          java.lang.Exception e)

Called when an exception is thrown during a call to closeStream.

Parameters:

stream - the stream the threw the exception

e - the exception thrown
