Interface VariableManager

All Known Implementing Classes:
AVM
public interface VariableManager
The AWK Variable Manager. It provides getter/setter methods for global AWK variables. Its purpose is to expose a variable management interface to the JRT, even though the implementation is provided by the AWK script at script compile-time.

The getters/setters here do not access all special AWK variables, such as RSTART and ENVIRON. That's because these variables are not referred to within the JRT.
