All Implemented Interfaces:: Serializable, ComponentAdapter<T>, ComponentMonitorStrategy, Injector<T>

Direct Known Subclasses:: AbstractFieldInjector, SetterInjector

public abstract class IterativeInjector<T> extends AbstractInjector<T>

Injection will happen iteratively after component instantiation

- IterativeInjector
  
  public IterativeInjector(Object componentKey, Class componentImplementation, Parameter[] parameters, ComponentMonitor monitor, 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
  
  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

- 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.
- memberInvocationReturn
  
  protected abstract Object memberInvocationReturn(Object lastReturn, AccessibleObject member, Object instance)
- decorateComponentInstance
  
  public Object decorateComponentInstance(PicoContainer container, Type into, T instance)
  
  Description copied from interface: Injector
  
  A preexiting component instance can be injected into after instantiation
  
  Specified by:
  
  decorateComponentInstance in interface Injector<T>
  
  Overrides:
  
  decorateComponentInstance in class AbstractInjector<T>
  
  Parameters:
  
  container - the container that can provide injectable dependencies
  
  into -
  
  instance - the instance to
  
  Returns:
- injectIntoMember
  
  protected abstract Object 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.
