public class AbstractComponentMonitor extends Object implements ComponentMonitor, ComponentMonitorStrategy, Serializable
A
monitor
which delegates to another monitor. It provides adefault ComponentMonitor
, but does not allow to usenull
for the delegate.It also supports a
monitor strategy
that allows to change the delegate.- See Also:

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
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 <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
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
-
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
constructor
- the Constructor used to instantiate the addComponente
- the Exception detailing the cause of the failure
-
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
instance
- the component instance
-
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
instance
- the component instance

-
noComponentFound
public Object noComponentFound(MutablePicoContainer container, Object componentKey)
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
-
newInjector
public Injector newInjector(Injector injector)
Description copied from interface:ComponentMonitor
A mechanism to monitor or override the Injectors being made for components.- Specified by:
newInjector
in interfaceComponentMonitor
- Returns:
- an Injector. For most implementations, the same one as was passed in.
-
newBehavior
public Behavior newBehavior(Behavior behavior)
Description copied from interface:ComponentMonitor
A mechanism to monitor or override the Behaviors being made for components.- Specified by:
newBehavior
in interfaceComponentMonitor
- Returns:
- an Behavior. For most implementations, the same one as was passed in.
-
changeMonitor
public void changeMonitor(ComponentMonitor monitor)
If the delegate supports amonitor strategy
, this is used to changed the monitor while keeping the same delegate. Else the delegate is replaced by the new monitor. Changes the component monitor used- Specified by:
changeMonitor
in interfaceComponentMonitorStrategy
- Parameters:
monitor
- the new ComponentMonitor to use
-
currentMonitor
public ComponentMonitor currentMonitor()
Description copied from interface:ComponentMonitorStrategy
Returns the monitor currently used- Specified by:
currentMonitor
in interfaceComponentMonitorStrategy
- Returns:
- The ComponentMonitor currently used
