Package org.springframework.web.context.request

Class AbstractRequestAttributesScope

java.lang.Object
org.springframework.web.context.request.AbstractRequestAttributesScope
All Implemented Interfaces:
org.springframework.beans.factory.config.Scope
Direct Known Subclasses:
RequestScope, SessionScope
public abstract class AbstractRequestAttributesScope extends Object implements org.springframework.beans.factory.config.Scope
Abstract Scope implementation that reads from a particular scope in the current thread-bound RequestAttributes object.

Subclasses simply need to implement getScope() to instruct this class which RequestAttributes scope to read attributes from.

Subclasses may wish to override the get(java.lang.String, org.springframework.beans.factory.ObjectFactory<?>) and remove(java.lang.String) methods to add synchronization around the call back into this superclass.
