getValue

public <V> V getValue(Object component,
                      Inhabitant<?> onBehalfOf,

                      Class<V> type)
           throws ComponentException

Description copied from interface: InjectionResolverQuery

Returns the value to inject in the field or method of component annotated with the annotated annotation.

Parameters:

component - injection target instance

onBehalfOf - inhabitant doing the injection for

target - is the annotated java element Method or Field

gtype - the generic type of the expected return

type - type of the expected return

Returns:

the resource to be injected

Throws:

ComponentException - if the resource cannot be located.

isOptional

public boolean isOptional(AnnotatedElement annotated,

Description copied from class: InjectionResolver

Returns true if the resolution of this injection identified by the passed annotation instance is optional

Overrides:

isOptional in class InjectionResolver<Inject>

Parameters:

annotated - is the annotated java element Method or Field

annotation - the injection metadata

Returns:

true if the getValue() can return null without generating a faulty injection operation
