Method Detail

instantiating

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

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

Parameters:

container -

componentAdapter -

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

instantiated

void instantiated(PicoContainer container,
                  ComponentAdapter componentAdapter,
                  Constructor constructor,
                  Object instantiated,
                  Object[] injected,
                  long duration)

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

Parameters:

container -

componentAdapter -

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

instantiationFailed

void instantiationFailed(PicoContainer container,
                         ComponentAdapter componentAdapter,
                         Constructor constructor,
                         Exception cause)

Event thrown if the component instantiation failed using the given constructor

Parameters:

container -

componentAdapter -

constructor - the Constructor used to instantiate the addComponent

cause - the Exception detailing the cause of the failure

invoking

void invoking(PicoContainer container,
              ComponentAdapter componentAdapter,
              Member member,
              Object instance)

Event thrown as the component method is being invoked on the given instance

Parameters:

container -

componentAdapter -

member -

instance - the component instance

invoked

void invoked(PicoContainer container,
             ComponentAdapter componentAdapter,
             Method method,
             Object instance,
             long duration)

Event thrown after the component method has been invoked on the given instance

Parameters:

container -

componentAdapter -

method - the Method invoked on the component instance

instance - the component instance

duration - the duration in millis of the invocation

invocationFailed

void invocationFailed(Member member,
                      Object instance,
                      Exception cause)

Event thrown if the component method invocation failed on the given instance

Parameters:

member -

instance - the component instance

cause - the Exception detailing the cause of the failure

lifecycleInvocationFailed

void lifecycleInvocationFailed(MutablePicoContainer container,
                               ComponentAdapter componentAdapter,
                               Method method,
                               Object instance,
                               RuntimeException cause)

Event thrown if a lifecycle method invocation - start, stop or dispose - failed on the given instance

Parameters:

container -

componentAdapter -

method - the lifecycle Method invoked on the component instance

instance - the component instance

cause - the RuntimeException detailing the cause of the failure

noComponentFound

Object noComponentFound(MutablePicoContainer container,
                        Object componentKey)

Parameters:

container -

componentKey -
