org.picocontainer.behaviors
Class HiddenImplementation

java.lang.Object
  org.picocontainer.behaviors.AbstractBehavior
      org.picocontainer.behaviors.HiddenImplementation

All Implemented Interfaces:

Serializable, Behavior, ComponentAdapter, ComponentMonitorStrategy, LifecycleStrategy

Direct Known Subclasses:

Intercepted

public class HiddenImplementation
extends AbstractBehavior

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.

Constructor Detail

HiddenImplementation

public HiddenImplementation(ComponentAdapter delegate)

Creates an ImplementationHidingComponentAdapter with a delegate

delegate - the component adapter to which this adapter delegates

Method Detail

getComponentInstance

public Object getComponentInstance(PicoContainer container)
                            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

Overrides:

getComponentInstance in class AbstractBehavior

Parameters:

container - the PicoContainer, that is used to resolve any possible dependencies of the instance.

Returns:

the component instance.

Throws:

PicoCompositionException - if the component could not be instantiated.

invokeMethod

protected Object invokeMethod(Method method,
                              Object[] args,
                              PicoContainer container)
                       throws Throwable

Throws:

Throwable

toString

public String toString()

Overrides:
