All Implemented Interfaces:

Closeable, Flushable, Appendable

public class VT100PrintStream
extends AbstractPrintStream

Provides a way to apply a VT100 style to all output that goes through it. It basically writes the style provided on construction before each output and then resets the style after it.
For example, to make all output have red background and bold white foreground text (e.g. for error output):

   VT100PrintStream error = new VT100PrintStream(new byte[][] {
     OutputFormatVT100Constants.ATTRS_BACK_RED,
     OutputFormatVT100Constants.ATTRS_FORE_WHITE,
     OutputFormatVT100Constants.STYLE_BOLD
   }, sessionState.getSession().getConsoleDelegate().getConsoleOutputStream(), true);
 

For more on how to compose VT100 style please refer to OutputFormatVT100Constants.
