Constructor & Destructor Documentation

◆ Terminal() [1/2]

aud.util.Terminal.Terminal ( boolean ansi )

Constructor.

Parameters

ansi	assume terminal emulation is available

Definition at line 101 of file util/Terminal.java.

                                {
    ansi_=ansi;
    if (!ansi)
      System.err.println("Assuming dumb terminal.");
  }

◆ Terminal() [2/2]

aud.util.Terminal.Terminal ( )

Constructor: guess availability of terminal emulation.

Simple rule: assume that Windows systems don't provide terminal emulation, all other systems do.

Definition at line 110 of file util/Terminal.java.

                    {
    this(!System.getProperty("os.name").startsWith("Windows"));
  }
