T
- This is the type produced by the cache and consumed by the cachepublic interface ActiveDescriptor<T> extends Descriptor, SingleCache<T>

.reifyDescriptor method.
ActiveDescriptors may also be provided to the system pre-reified, which is useful when the Service described may be produced by a third-party system. In this case the ActiveDescriptors create method must use the third-party system in order to create instances of the described service
Modifier and Type | Method and Description |

getFactoryLocatorId()
If this ActiveDescriptor has DescriptorType of PROVIDE_METHOD then
this field will return the ServiceId of its associated Factory
service.

getFactoryServiceId()
If this ActiveDescriptor has DescriptorType of PROVIDE_METHOD then
this field will return the ServiceId of its associated Factory
service.

If the class returned is a Factory, then the factory is used to create instances. In this case the system will get an instance of the factory and use it to create the instances
