All Known Implementing Classes:

CollectionExpressionVariable, CollectionsExpressionVariable, DateExpressionVariable, DecimalExpressionVariable, LocaleExpressionVariable, MoneyExpressionVariable, ObjectExpressionVariable, StringExpressionVariable
```
public interface ExpressionVariable
```
Implementations of this class are to be used as expression variables such as in SpEL expression. This provides a means whereby helpful utility classes can be injected into expressions and made generally available.

By default, a number of expression variables should be added to any EvaluationContext generated by an EvaluationContextFactory
