Class AdaptingInjection

java.lang.Object
org.picocontainer.injectors.AbstractInjectionFactory
org.picocontainer.injectors.AdaptingInjection
All Implemented Interfaces:
Serializable, ComponentFactory, InjectionFactory

public class AdaptingInjection extends AbstractInjectionFactory
Creates injector instances, depending on the injection characteristics of the component class. It will attempt to create a component adapter with - in order of priority:
  1. Annotated field injection: if annotation Inject is found for field
  2. Annotated method injection: if annotation Inject is found for method
  3. Setter injection: if
    invalid reference
    Characteristics.SDI
    is found
  4. Method injection: if
    invalid reference
    Characteristics.METHOD_INJECTION
    if found
  5. Constructor injection (the default, must find
    invalid reference
    Characteristics.CDI
    )

      Description copied from interface: ComponentFactory
      Create a new component adapter based on the specified arguments.
      Parameters:
      componentMonitor - the component monitor
      lifecycleStrategy - te lifecycle strategy
      componentProperties - the component properties
      componentKey - the key to be associated with this adapter. This value should be returned from a call to ComponentAdapter.getComponentKey() on the created adapter.
      componentImplementation - the implementation class to be associated with this adapter. This value should be returned from a call to ComponentAdapter.getComponentImplementation() on the created adapter. Should not be null.
      parameters - additional parameters to use by the component adapter in constructing component instances. These may be used, for example, to make decisions about the arguments passed into the component constructor. These should be considered hints; they may be ignored by some implementations. May be null, and may be of zero length.
      Returns:
      a new component adapter based on the specified arguments. Should not return null.
      Throws:
      PicoCompositionException - if the creation of the component adapter results in a PicoCompositionException.
