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.

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.

verify

public void verify(PicoContainer container)
            throws PicoCompositionException

Description copied from interface: ComponentAdapter

Verify that all dependencies for this adapter can be satisifed. Normally, the adapter should verify this by checking that the associated PicoContainer contains all the needed dependnecies.

Specified by:

verify in interface ComponentAdapter

Specified by:

verify in class AbstractInjector

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.
