Method Detail

isOptional

public boolean isOptional(java.lang.reflect.AnnotatedElement element,
                          Inject annotation)

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:

element - 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

getValue

public <V> V getValue(java.lang.Object component,
                      Inhabitant<?> onBehalfOf,
                      java.lang.reflect.AnnotatedElement target,
                      java.lang.reflect.Type genericType,
                      java.lang.Class<V> type)
           throws ComponentException

Obtains the value to inject, based on the type and Inject annotation.

Specified by:

getValue in class InjectionResolver<Inject>

Parameters:

component - injection target instance

onBehalfOf - inhabitant doing the injection for

target - is the annotated java element Method or Field

genericType - 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.
