package org.springframework.beans.factory;


A marker superinterface indicating that a bean is eligible to be notified by the
Spring container of a particular framework object through a callback-style method.
The actual method signature is determined by individual subinterfaces but should
typically consist of just one void-returning method that accepts a single argument.

Note that merely implementing Aware provides no default functionality. Rather, processing must be done explicitly, for example in a BeanPostProcessor. Refer to ApplicationContextAwareProcessor for an example of processing specific *Aware interface callbacks.
