ServiceLoader. Java 6 has introduced a feature for discovering and loading implementations matching a given interface: Service Provider Interface (SPI). /** * Basic test for ServiceLoader. The following are Jave code examples for showing how to use reload() of the java.util.ServiceLoader class. This is typically accomplished by creating an interface describing the actions the component can perform, and using some kind of intermediary to create the component instances. You can vote up the examples you like. have been installed into the current Java virtual machine; providers on Service loaders always execute in the security context of the caller. provider classes must have a zero-argument constructor so that they can be security context.
