BeanDefinitionVisitor (Spring Framework API 2.0) - Spring Framework 2.0.5 API 文档英文版

The Spring Framework

org.springframework.beans.factory.config
Class BeanDefinitionVisitor

java.lang.Object
  extended by org.springframework.beans.factory.config.BeanDefinitionVisitor

public abstract class BeanDefinitionVisitor
extends Object

Visitor base class for traversing BeanDefinition objects, in particular the property values and constructor argument values contained in them.

The abstract resolveStringValue(java.lang.String) method has to be implemented in concrete subclasses, following arbitrary resolution strategies.

Used by PropertyPlaceholderConfigurer to parse all String values contained in a BeanDefinition, resolving any placeholders found.

1.2
