- All Implemented Interfaces:
- Serializable, ComponentAdapter<T>, ComponentMonitorStrategy, Injector<T>, LifecycleStrategy
public class MethodInjector<T>
- extends SingleMemberInjector<T>
Injection will happen through a single method for the component.
Most likely it is a method called 'inject', though that can be overridden.

MethodInjector
public MethodInjector(Object componentKey,
Class componentImplementation,
Parameter[] parameters,
ComponentMonitor monitor,
LifecycleStrategy lifecycleStrategy,
String methodName,
boolean useNames)
throws AbstractInjector.NotConcreteRegistrationException
- Creates a MethodInjector
- Parameters:
componentKey
- the search key for this implementationcomponentImplementation
- the concrete implementationparameters
- the parameters to use for the initializationmonitor
- the component monitor used by this addAdapterlifecycleStrategy
- the component lifecycle strategy used by this addAdaptermethodName
- the method nameuseNames
- 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
getInjectorMethod
protected Method getInjectorMethod()
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.
getMemberArguments
protected Object[] getMemberArguments(PicoContainer container,
Method method)
decorateComponentInstance
public void decorateComponentInstance(PicoContainer container,
Type into,
T instance)
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.
getDescriptor
public String getDescriptor()
- Description copied from interface:
ComponentAdapter
- Get a string key descriptor of the component adapter.
- Specified by:
getDescriptor
in interface ComponentAdapter<T>
- Overrides:
getDescriptor
in class AbstractInjector<T>
- Returns:
