weka.core.Environment
This class encapsulates a map of all environment and java system properties. There are methods for adding and removing variables as well as a method for replacing key names (enclosed by ${}) with their associated value in Strings. @author Mark Hall (mhall{[at]}pentaho{[dot]}com) @version $Revision: 5562 $
