- the concrete implementationparameters
- the parameters to use for the initializationmonitor
- the component monitor used by this addAdapteruseNames
- use argument names when looking up dependencies- Throws:
AbstractInjector.NotConcreteRegistrationException
- if the implementation is not a concrete class.NullPointerException

getComponentInstance
Description copied from interface:ComponentAdapter
Retrieve the component instance. This method will usually create a new instance each time it is called, but that is not required. For example,Cached
will always return the same instance.- Specified by:
getComponentInstance
in interfaceComponentAdapter<T>
- Specified by:
getComponentInstance
in classAbstractInjector<T>
- Parameters:
container
- thePicoContainer
, that is used to resolve any possible dependencies of the instance.into
- the class that is about to be injected into. Use ComponentAdapter.NOTHING.class if this is not important to you.- Returns:
- the component instance.
- Throws:
PicoCompositionException
- if the component has dependencies which could not be resolved, or instantiation of the component lead to an ambiguous situation within the container.
-
memberInvocationReturn
protected abstract Object memberInvocationReturn(Object lastReturn, AccessibleObject member, Object instance) -
decorateComponentInstance
Description copied from interface:Injector
A preexiting component instance can be injected into after instantiation- Specified by:
decorateComponentInstance
in interfaceInjector<T>
- Overrides:
decorateComponentInstance
in classAbstractInjector<T>
- Parameters:
container
- the container that can provide injectable dependenciesinto
-instance
- the instance to- Returns:
-
injectIntoMember
protected abstract Object injectIntoMember(AccessibleObject member, Object componentInstance, Object toInject) throws IllegalAccessException, InvocationTargetException -
verify
Description copied from interface:ComponentAdapter
Verify that all dependencies for this adapter can be satisfied. Normally, the adapter should verify this by checking that the associated PicoContainer contains all the needed dependencies.- Specified by:
verify
in interfaceComponentAdapter<T>
- Overrides:
verify
in classAbstractInjector<T>
- Parameters:
container
- thePicoContainer
, that is used to resolve any possible dependencies of the instance.- Throws:
PicoCompositionException
- if one or more dependencies cannot be resolved.
