Class TextComponentStream

java.lang.Object

  java.io.OutputStream

      com.lightdev.app.ddnscl.io.TextComponentStream

public class TextComponentStream

extends OutputStream

a custom OutputStream that allows to optionally echo output to a JTextArea.

In this application this stream is used to log messages to a JTextArea. For this purpose the application logger is extended by an additional StreamHandler which allows the logger to log to an instance of this class. Upon initialization of the application, a JTextArea is registered to this TextComponentStream so that all logging to this stream finally is shown in the JTextArea.
