All Superinterfaces:

MadxVariable, TwissVariable, Variable

All Known Implementing Classes:

CustomVariableImpl
```
public interface CustomVariable
extends TwissVariable
```
This is the interface of a variable. It represents a madx definition of a key-value pair. A Variable may be e.g. parsed from a strength file and then plotted in a gui. For the moment the expression of a variable can not be explicitely set and the name can not be changed.
