Method Detail

resolve

public java.lang.Object resolve(Injectee injectee,
                                ServiceHandle<?> root)

Description copied from interface: InjectionResolver

This method will return the object that should be injected into the given injection point. It is the responsiblity of the implementation to ensure that the object returned can be safely injected into the injection point.

This method should not do the injection themselves

Specified by:

resolve in interface InjectionResolver<ChildInject>

Parameters:

injectee - The injection point this value is being injected into

root - The service handle of the root class being created, which should be used in order to ensure proper destruction of associated &64;PerLookup scoped objects. This can be null in the case that this is being used for an object not managed by HK2. This will only happen if this object is being created with the create method of ServiceLocator.

Returns:

A possibly null value to be injected into the given injection point

getInjectionAnnotation

private static ChildInject getInjectionAnnotation(java.lang.reflect.AnnotatedElement element,
                                                  int position)

isConstructorParameterIndicator

public boolean isConstructorParameterIndicator()

Description copied from interface: InjectionResolver

This method should return true if the annotation that indicates that this is an injection point can appear in the parameter list of a constructor.

Specified by:

isConstructorParameterIndicator in interface InjectionResolver<ChildInject>

Returns:

true if the injection annotation can appear in the parameter list of a constructor

isMethodParameterIndicator

public boolean isMethodParameterIndicator()

Description copied from interface: InjectionResolver

This method should return true if the annotation that indicates that this is an injection point can appear in the parameter list of a method.

Specified by:

isMethodParameterIndicator in interface InjectionResolver<ChildInject>

Returns:

true if the injection annotation can appear in the parameter list of a method
