Interface ServiceRegistry

All Known Implementing Classes:

SPIServiceRegistry

public interface ServiceRegistry

API component to be used as standard SPI discovery mechanism. Locates and returns all registered instances of a given provider class. Advantages of using this interface instead of hitting something like ServiceLoader directly are the ability to inject a different lookup mechanism and to facilitate testing.

Notice that in future versions of Mule this interface might me moved to a new higher level mule-api artifact

Since:

3.7.0
