getComponentInstance
public T getComponentInstance(PicoContainer container, java.lang.reflect.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 interfaceComponentAdapter<T>
- Specified by:
getComponentInstance
in classAbstractInjector<T>
- Parameters:
container
- thePicoContainer
, 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 java.lang.Object decorateComponentInstance(PicoContainer container, java.lang.reflect.Type into, T instance)
Description copied from interface:Injector
A preexiting component instance can be injected into after instantiation- Specified by:
decorateComponentInstance
in interfaceInjector<T>
- Overrides:
decorateComponentInstance
in classAbstractInjector<T>
- Parameters:
container
- the container that can provide injectable dependenciesinstance
- the instance to- Returns:
-
injectIntoMember
protected abstract java.lang.Object injectIntoMember(java.lang.reflect.AccessibleObject member, java.lang.Object componentInstance, java.lang.Object toInject) throws java.lang.IllegalAccessException, java.lang.reflect.InvocationTargetException
- Throws:
java.lang.IllegalAccessException
java.lang.reflect.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 interfaceComponentAdapter<T>
- Overrides:
verify
in classAbstractInjector<T>
- Parameters:
container
- thePicoContainer
, that is used to resolve any possible dependencies of the instance.- Throws:
PicoCompositionException
- if one or more dependencies cannot be resolved.
