instantiating
public <T> Constructor<T> instantiating(PicoContainer container, ComponentAdapter<T> componentAdapter, Constructor<T> constructor) Description copied from interface:ComponentMonitor
Event thrown as the component is being instantiated using the given constructor- Specified by:
instantiating
in interfaceComponentMonitor
- 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)
-
instantiationFailed
public <T> void instantiationFailed(PicoContainer container, ComponentAdapter<T> componentAdapter, Constructor<T> constructor, Exception e) Description copied from interface:ComponentMonitor
Event thrown if the component instantiation failed using the given constructor- Specified by:
instantiationFailed
in interfaceComponentMonitor
- Parameters:
container
-componentAdapter
-constructor
- the Constructor used to instantiate the addComponente
- the Exception detailing the cause of the failure
-
instantiated
public <T> void instantiated(PicoContainer container, ComponentAdapter<T> componentAdapter, Constructor<T> constructor, Object instantiated, Object[] injected, 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 interfaceComponentMonitor
- Parameters:
container
-componentAdapter
-constructor
- the Constructor used to instantiate the addComponentinstantiated
- the component that was instantiated by PicoContainerinjected
- the components during instantiation.duration
- the duration in milliseconds of the instantiation
-
invoking
public Object invoking(PicoContainer container, ComponentAdapter<?> componentAdapter, Member member, Object instance, Object[] args) Description copied from interface:ComponentMonitor
Event thrown as the component method is being invoked on the given instance- Specified by:
invoking
in interfaceComponentMonitor
- Parameters:
container
-componentAdapter
-member
-instance
- the component instanceargs
-
-
invoked
public void invoked(PicoContainer container, ComponentAdapter<?> componentAdapter, Member member, Object instance, long duration, Object[] args, Object retVal) Description copied from interface:ComponentMonitor
Event thrown after the component method has been invoked on the given instance- Specified by:
invoked
in interfaceComponentMonitor
- Parameters:
container
-componentAdapter
-member
-instance
- the component instanceduration
-args
-retVal
-
-
invocationFailed
Description copied from interface:ComponentMonitor
Event thrown if the component method invocation failed on the given instance- Specified by:
invocationFailed
in interfaceComponentMonitor
- Parameters:
member
-instance
- the component instancee
- the Exception detailing the cause of the failure
-
lifecycleInvocationFailed
public void lifecycleInvocationFailed(MutablePicoContainer container, ComponentAdapter<?> componentAdapter, Method method, Object instance, RuntimeException cause) Description copied from interface:ComponentMonitor
Event thrown if a lifecycle method invocation - start, stop or dispose - failed on the given instance- Specified by:
lifecycleInvocationFailed
in interfaceComponentMonitor
- Parameters:
container
-componentAdapter
-method
- the lifecycle Method invoked on the component instanceinstance
- the component instancecause
- the RuntimeException detailing the cause of the failure
-
noComponentFound
Description copied from interface:ComponentMonitor
No Component has been found for the key in question. Implementers of this have a last chance opportunity to specify something for the need. This is only relevant to component dependencies, and not to container.getComponent() in your user code. - Specified by:
noComponentFound
in interfaceComponentMonitor
- Parameters:
container
-componentKey
-
-
newInjector
Description copied from interface:ComponentMonitor
A mechanism to monitor or override the Injectors being made for components.- Specified by:
newInjector
in interfaceComponentMonitor
- Parameters:
injector
-- Returns:
- an Injector. For most implementations, the same one as was passed in.
-
newBehavior
A mechanism to monitor or override the Behaviors being made for components.- Specified by:
newBehavior
in interfaceComponentMonitor
- Parameters:
behavior
-- Returns:
- an Behavior. For most implementations, the same one as was passed in.
