        Parameters:
        name - the name of the variable
        Returns:
        the variable or null if not found

      • isDefined

        public boolean isDefined​(D var)
        Returns whether var is defined (a value was assigned).
        Parameters:
        var - the variable to look for
        Returns:
        true if var is defined, false else

      • isDefined

        private boolean isDefined​(D var,
                          int maxIndex)
        Returns whether var is defined (a value was assigned).
        Parameters:
        var - the variable to look for
        maxIndex - the maximum level index to start searching for
        Returns:
        true if var is defined, false else

      • setValue

        public void setValue​(D var,
                     java.lang.Object object)
              throws VilException
        Changes the value of var where it is defined.
        Parameters:
        var - the variable to be modified
        object - the value of var

      • popLevel

        public void popLevel()
              throws VilException
        Removes the topmost level.
        Throws:
