IStandardVariableExpressionEvaluator (thymeleaf 3.0.12.RELEASE API)

All Known Implementing Classes:

OGNLVariableExpressionEvaluator
```
public interface IStandardVariableExpressionEvaluator
```
Common interface for all objects in charge of executing variable expressions (${...}) inside Thymeleaf Standard Expressions.

The basic implementation of this interface evaluates expressions using OGNL OGNLVariableExpressionEvaluator, but a SpringEL version also exists in the Thymeleaf + Spring integration package.

Implementations of this interface should be thread-safe.

Note a class with this name existed since 2.0.9, but it was completely reimplemented in Thymeleaf 3.0

Since:

3.0.0
