```
public interface IStandardExpression
```
Common interface for all Thymeleaf Standard Expression objects.

Objects implementing this inteface are obtained by calling the parsing methods in parser objects (implementations of IStandardExpressionParser).

Default implementation (used by most of the Thymeleaf core): Expression.

Note a class with this name existed since 2.1.0, but it was completely reimplemented in Thymeleaf 3.0

Since:

3.0.0
