Constructor Detail

ContextReplacementUtility

public ContextReplacementUtility(DependentAnnotationConfigApplicationContext context,
                                 PrototypeBeanRegistry instantiatedPrototypes)

Constuctor.

Parameters:

context - reference to the application context

instantiatedPrototypes - reference to the property bean registry

Method Detail

replace

public <T> boolean replace(T bean,
                           T instantiatedBean,
                           java.util.Set<IRebinabable> rebindalbeObjects)

Replace all references to the bean in other registered beans and replace it in the context. If the bean is not instanciated and stored in the context false will be returned. This may happen for lazy beans that are not yet instantiated or beans of Scope prototype which are not stored in the context.

Type Parameters:

T - type of the bean

Parameters:

bean - that will replace the existing bean

instantiatedBean - bean currently in the context

rebindalbeObjects - set of beans that are rebindable

Returns:

true if all references and the instance in the context were replaced.

replaceInContext

<T> void replaceInContext(T replacement,
                          T instantiatedBean)

replaceWiredBean

<T> void replaceWiredBean(java.lang.Object b,
                          T bean,
                          T instanciatedBean,
                          java.util.Set<IRebinabable> rebindalbeObjects)

Replace the instance instanciatedBean of type T in b that is wired with bean. T is a singleton bean.

Type Parameters:

T - type of the bean

Parameters:

b - Bean in which the new bean should be replaced

bean - that there reference should be replaced with.

instanciatedBean - bean currently in the context

rebindalbeObjects - set of beans that are rebindable
