Constructor Detail

IterativeInjector

public IterativeInjector(Object componentKey,
                         Class componentImplementation,
                         Parameter[] parameters,
                         ComponentMonitor monitor,
                         LifecycleStrategy lifecycleStrategy,
                         boolean useNames)
                  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
useNames - use argument names when looking up dependencies
Throws:
AbstractInjector.NotConcreteRegistrationException - if the implementation is not a concrete class.
NullPointerException - if one of the parameters is null
Method Detail

getParanamer

protected com.thoughtworks.paranamer.CachingParanamer getParanamer()

getConstructor

protected Constructor getConstructor()

makeParameterNameImpl

protected NameBinding makeParameterNameImpl(AccessibleObject member)

unsatisfiedDependencies

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

getComponentInstance

public T getComponentInstance(PicoContainer container,
                              Type into)
                       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.

Specified by:
getComponentInstance in interface ComponentAdapter<T>
Specified by:
getComponentInstance in class AbstractInjector<T>
Parameters:
container - the PicoContainer, 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.

decorateComponentInstance

public void decorateComponentInstance(PicoContainer container,
                                      Type into,
                                      T instance)

injectIntoMember

protected abstract void injectIntoMember(AccessibleObject 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 satisfied. Normally, the adapter should verify this by checking that the associated PicoContainer contains all the needed dependencies.

Specified by:
verify in interface ComponentAdapter<T>
Overrides:
verify in class AbstractInjector<T>
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)
