Interface BeanExpressionResolver

All Known Implementing Classes:
StandardBeanExpressionResolver
public interface BeanExpressionResolver
Strategy interface for resolving a value by evaluating it as an expression, if applicable.

A raw BeanFactory does not contain a default implementation of this strategy. However, ApplicationContext implementations will provide expression support out of the box.
