- All Implemented Interfaces:
Serializable
,ComponentFactory
,InjectionFactory
- Direct Known Subclasses:
ForgetfulConstructorInjection
A
InjectionFactory
for constructor injection.
The factory creates ConstructorInjector
.
If there is more than one constructor for the component, the one with the
most satisfiable parameters will be used. By default, the choice of
constructor for the component in question will be remembered between usages.- Author:

createComponentAdapter
public <T> ComponentAdapter<T> createComponentAdapter(ComponentMonitor monitor, LifecycleStrategy lifecycleStrategy, Properties properties, Object componentKey, Class<T> componentImplementation, Parameter... parameters) throws PicoCompositionException Description copied from interface:ComponentFactory
Create a new component adapter based on the specified arguments.- Parameters:
monitor
- the component monitorlifecycleStrategy
- te lifecycle strategyproperties
- the component propertiescomponentKey
- the key to be associated with this adapter. This value should be returned from a call toComponentAdapter.getComponentKey()
on the created adapter.componentImplementation
- the implementation class to be associated with this adapter. This value should be returned from a call toComponentAdapter.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 aPicoCompositionException
