Class Env

java.lang.Object

org.trianacode.gui.util.Env

public final class Env
extends java.lang.Object

Env allows a way of accessing various environment and system variables within Triana. Some methods convert from the Java system properties to suitable labels which are of more use within Triana. To get the particular variable you want just call any of these functions from within any unit e.g. :-

Env.trianahome()

returns triana's getApplicationDataDir directory.

The toString() method is also useful for identifying all the system properties at run-time to make sure your system is set up correctly. This message is printed out Triana or Triana is used.
