Interface IStandardVariableExpressionEvaluator
- 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
