Class SPELContextPropertyAccessor

Object

org.thymeleaf.spring4.expression.SPELContextPropertyAccessor

All Implemented Interfaces:

org.springframework.expression.PropertyAccessor

public final class SPELContextPropertyAccessor
extends Object
implements org.springframework.expression.PropertyAccessor

Property accessor used for allowing Spring EL expression evaluators treat IContext objects correctly (map keys will be accessible as object properties).

Note that, even if IContext objects used as expression roots will be accessible as java.util.Maps thanks to SPELContextMapWrapper, this property accessor class is still needed in order to access nested context info like the session or param maps in web contexts.

Since:

3.0.0
