Method Detail

instantiating

public Constructor instantiating(PicoContainer container,
                                 ComponentAdapter componentAdapter,
                                 Constructor constructor)

Description copied from interface: ComponentMonitor

Event thrown as the component is being instantiated using the given constructor

Specified by:

instantiating in interface ComponentMonitor

constructor - the Constructor used to instantiate the addComponent @return the constructor to use in instantiation (nearly always the same one as passed in)

instantiated

public void instantiated(PicoContainer container,
                         ComponentAdapter componentAdapter,
                         Constructor constructor,

                         long duration)

Description copied from interface: ComponentMonitor

Event thrown after the component has been instantiated using the given constructor. This should be called for both Constructor and Setter DI.

Specified by:

instantiated in interface ComponentMonitor

constructor - the Constructor used to instantiate the addComponent

instantiated - the component that was instantiated by PicoContainer

injected - the components during instantiation.

duration - the duration in millis of the instantiation
