Constructor Detail

DemoApplication

public DemoApplication(java.io.InputStream input,
                       java.io.OutputStream output)
                throws java.io.UnsupportedEncodingException

Public constructor.

Parameters:

input - an InputStream connected to the remote user, or null for System.in. If System.in is used, then on non-Windows systems it will be put in raw mode; shutdown() will (blindly!) put System.in in cooked mode. input is always converted to a Reader with UTF-8 encoding.

output - an OutputStream connected to the remote user, or null for System.out. output is always converted to a Writer with UTF-8 encoding.

Throws:

java.io.UnsupportedEncodingException - if an exception is thrown when creating the InputStreamReader

DemoApplication

public DemoApplication(java.io.InputStream input,
                       java.io.Reader reader,
                       java.io.PrintWriter writer,
                       boolean setRawMode)

Public constructor.

Parameters:

input - the InputStream underlying 'reader'. Its available() method is used to determine if reader.read() will block or not.

reader - a Reader connected to the remote user.

writer - a PrintWriter connected to the remote user.

setRawMode - if true, set System.in into raw mode with stty. This should in general not be used. It is here solely for Demo3, which uses System.in.

Throws:

java.lang.IllegalArgumentException - if input, reader, or writer are null.

DemoApplication

public DemoApplication(java.io.InputStream input,
                       java.io.Reader reader,
                       java.io.PrintWriter writer)

Public constructor.

Parameters:

input - the InputStream underlying 'reader'. Its available() method is used to determine if reader.read() will block or not.

reader - a Reader connected to the remote user.

writer - a PrintWriter connected to the remote user.

Throws:

java.lang.IllegalArgumentException - if input, reader, or writer are null.

DemoApplication

public DemoApplication(Backend backend)

Public constructor.

Parameters:

backend - a Backend that is already ready to go.

DemoApplication

public DemoApplication(TApplication.BackendType backendType)
                throws java.lang.Exception

Public constructor.

Parameters:

backendType - one of the TApplication.BackendType values

Throws:

java.lang.Exception - if TApplication can't instantiate the Backend.
