Produce a value for an injection point.

Specified by:

getValue in interface Injector

Parameters:

adaptable - the object which should be used as the basis for value resolution.

name - the injection point name (may be only null if injector implements the AcceptsNullName interface, otherwise never null)

declaredType - the declared type of the injection point

element - the injection point itself

callbackRegistry - a registry object to register a callback object which will be invoked when the adapted object is disposed.

Returns:

the value to be injected or null if no value could be resolved

createAnnotationProcessor

public InjectAnnotationProcessor2 createAnnotationProcessor(Object adaptable,
 AnnotatedElement element)

Specified by:

createAnnotationProcessor in interface InjectAnnotationProcessorFactory2

Parameters:

adaptable - the object from which this model is adapted

element - the field or method which is annotated

Returns:

a ModelAnnotationProcessor in case there is a known injector-specific annotation on the given element found otherwise null

getResourceResolver

protected ResourceResolver getResourceResolver(Object adaptable)

getValueMap

@Nullable
protected @Nullable ValueMap getValueMap(Object adaptable)

Retrieve the ValueMap from the given adaptable. This succeeds, if the adaptable is either
