Constructor Detail

IterativeInjector

public IterativeInjector(Object componentKey,
                         Class componentImplementation,
                         Parameter[] parameters,
                         ComponentMonitor monitor,
                         LifecycleStrategy lifecycleStrategy)
                  throws AbstractInjector.NotConcreteRegistrationException

Constructs a IterativeInjector

Parameters:

componentKey - the search key for this implementation

componentImplementation - the concrete implementation

parameters - the parameters to use for the initialization

monitor - the component monitor used by this addAdapter

lifecycleStrategy - the component lifecycle strategy used by this addAdapter

Throws:

AbstractInjector.NotConcreteRegistrationException - if the implementation is not a concrete class.

NullPointerException - if one of the parameters is null

Method Detail

getConstructor

protected Constructor getConstructor()

unsatisfiedDependencies

protected void unsatisfiedDependencies(PicoContainer container,
                                       Set<Class> unsatisfiableDependencyTypes)

getComponentInstance

public Object getComponentInstance(PicoContainer container)
                            throws PicoCompositionException

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.

Parameters:

container - the PicoContainer, that is used to resolve any possible dependencies of the instance.

Returns:

the component instance.

Throws:

PicoCompositionException - if the component could not be instantiated.

getOrMakeInstance

protected Object getOrMakeInstance(PicoContainer container,
                                   Constructor constructor,
                                   ComponentMonitor componentMonitor)

injectIntoMember

protected void injectIntoMember(Member member,
                                Object componentInstance,
                                Object toInject)
                         throws IllegalAccessException,
                                InvocationTargetException

Throws:

IllegalAccessException

InvocationTargetException

verify

public void verify(PicoContainer container)
            throws PicoCompositionException

Description copied from interface: ComponentAdapter

Verify that all dependencies for this adapter can be satisifed. Normally, the adapter should verify this by checking that the associated PicoContainer contains all the needed dependnecies.

Specified by:

verify in interface ComponentAdapter

Specified by:

verify in class AbstractInjector

Parameters:

container - the PicoContainer, that is used to resolve any possible dependencies of the instance.

Throws:

PicoCompositionException - if one or more dependencies cannot be resolved.

initializeInjectionMembersAndTypeLists

protected void initializeInjectionMembersAndTypeLists()

isInjectorMethod

protected boolean isInjectorMethod(Method method)
