Class ThymeleafEvaluationContext

Object

org.springframework.expression.spel.support.StandardEvaluationContext

org.thymeleaf.spring5.expression.ThymeleafEvaluationContext

All Implemented Interfaces:

org.springframework.expression.EvaluationContext, IThymeleafEvaluationContext

public final class ThymeleafEvaluationContext
extends org.springframework.expression.spel.support.StandardEvaluationContext
implements IThymeleafEvaluationContext

Thymeleaf's basic implementation of the IThymeleafEvaluationContext interface, which in turn extends from Spring's EvaluationContext interface.

This implementation adds Thymeleaf's own property accessors (see PropertyAccessor) for accessing the IContext object in which variables are stored.

Also, this evaluation context (which is usually instanced at the ThymeleafView initialization) links the execution of expressions with the available BeanFactory and ConversionService instances, used during evaluation.

Before executing a Spring EL expression using this evaluation context, it should be enriched with the variables to be made accessible (like #variableName), using a ThymeleafEvaluationContextWrapper object.

Since:

3.0.3
