Method Detail

instantiating

void instantiating(java.lang.reflect.Constructor constructor)

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

Parameters:

constructor - the Constructor used to instantiate the component

instantiated

void instantiated(java.lang.reflect.Constructor constructor,
                long duration)

Deprecated. since 1.3

Event thrown after the component has been instantiated using the given constructor

Parameters:

constructor - the Constructor used to instantiate the component

duration - the duration in millis of the instantiation

instantiated

void instantiated(java.lang.reflect.Constructor constructor,
                java.lang.Object instantiated,
                java.lang.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:

constructor - the Constructor used to instantiate the component

instantiated - the component that was instantiated by PicoContainer

injected - the components during instantiation.

duration - the duration in millis of the instantiation

Since:

1.3

instantiationFailed

void instantiationFailed(java.lang.reflect.Constructor constructor,
                       java.lang.Exception cause)

Event thrown if the component instantiation failed using the given constructor

Parameters:

constructor - the Constructor used to instantiate the component

cause - the Exception detailing the cause of the failure

invoking

void invoking(java.lang.reflect.Method method,
            java.lang.Object instance)

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

Parameters:

method - the Method invoked on the component instance

instance - the component instance

invoked

void invoked(java.lang.reflect.Method method,
           java.lang.Object instance,
           long duration)

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

Parameters:

method - the Method invoked on the component instance

instance - the component instance

duration - the duration in millis of the invocation

invocationFailed

void invocationFailed(java.lang.reflect.Method method,
                    java.lang.Object instance,
                    java.lang.Exception cause)

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

Parameters:

method - the Method invoked on the component instance

instance - the component instance

cause - the Exception detailing the cause of the failure

lifecycleInvocationFailed

void lifecycleInvocationFailed(java.lang.reflect.Method method,
                             java.lang.Object instance,
                             java.lang.RuntimeException cause)

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

Parameters:

method - the lifecycle Method invoked on the component instance

instance - the component instance

cause - the RuntimeException detailing the cause of the failure
