Class ScopedProxyManager

java.lang.Object

jodd.petite.ScopedProxyManager

public class ScopedProxyManager
extends java.lang.Object

Manager for mixing scopes. 'Mixed scopes' is the situation when 'smaller' scope is injected into the 'bigger' scope. Trivial example is when prototype scoped bean is injected into singleton bean.

Mixed scopes are handled using smart factory/proxy-wrapper singletons instead of 'smaller' scoped beans. On each method call of wrapped factory, smaller scoped bean will be looked up and that instance will be used for passing by the method call.

Manager also has to determine if scope combination is candidate for mixed scopes.
