This allows a processor in the given project to A processor can then define the SSLContextService with a property as follows:

public static final PropertyDescriptor SSL_CONTEXT_SERVICE = new PropertyDescriptor.Builder()

            .name("SSL Context Service")

            .description("The Controller Service to use in order to obtain an SSL Context")

            .required(false)

            .identifiesControllerService(SSLContextService.class)

            .build();

An instance of the service can then be obtained as follows:

final SSLContextService sslContextService = context.getProperty(SSL_CONTEXT_SERVICE).asControllerService(SSLContextService.class);

The service returned from the context will correspond with the implementation that was configured in the NiFi user interface. Configuring ControllerServices through the user interface is described in detail in the user guide.

The  The nifi-standard-services module contains the shared APIs that can be leveraged. Browsing this module can provide the groupId, artifactId, and version of the various APIs.
