Method Detail

inject

public static final void inject(Object object,
                                Factory factory)

Inject ICS runtime objects into the object. Objects flagged with the InjectForRequest annotation will be populated by this method by retrieving the value from the Factory.getObject(String,Class) method.

Parameters:

object - the object to inject into

factory - the factory that created the objects that need to be injected.

findFieldsWithAnnotation

public static final Field[] findFieldsWithAnnotation(Object object,
                                                     Class<? extends Annotation> annnotationClass)

Finds the fields in the class or super class that are annotated with the annnotationClass annotation.

Parameters:

object - the object to inspect.

annnotationClass - the annotation to find.

Returns:

the array of fields with the annotation, never null.

injectIntoField

public static void injectIntoField(Object object,
                                   Factory factory,
                                   Field field)
