This component adapter makes it possible to hide the implementation
of a real subject (behind a proxy) provided the key is an interface.
This class exists here, because a) it has no deps on external jars, b) dynamic proxy is quite easy.
The user is prompted to look at picocontainer-gems for alternate and bigger implementations.

getComponentInstance
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>
- Overrides:
getComponentInstance
in classAbstractBehavior<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.
-
getDescriptor
Description copied from interface:ComponentAdapter
Get a string key descriptor of the component adapter for use in toString()- Returns:
- the descriptor

Throwable
