Method Summary

void	addToAssignees(java.lang.String template, ActivationRecord activationRecord) Creates any random objects on RHS of initialization or assignment and adds variables on RHS to the list of objects to which the access variable points - so that these objects can be displayed in the drop-down menu for the access variable
java.lang.Object	clone() Returns a clone of this object, and provides the basis for cloning of derived classes
