public abstract class SimpleVar
extends Var

Abstract superclass of all Simple Var Language variables that resolve to simple returned string values.

Note the difference between this class and StreamedVar that streams values to writers.
Unlike the StreamedVar class, the returned value from this class can contain nested variables that will be recursively resolved by VarResolver.

Subclasses must implement the following method:

• Var.resolve(VarResolverSession, String)
