/**
 * Describes a Controller Service API that is provided by some implementation.
 *
 * Please note that while this class lives within the nifi-api, it is provided primarily as a means for documentation components within
 * the NiFi NAR Maven Plugin. Its home is the nifi-api, however, because the API is needed in order to extract the relevant information and
 * the NAR Maven Plugin cannot have a direct dependency on nifi-api (doing so would cause a circular dependency). By having this homed within
 * the nifi-api, the Maven plugin is able to discover the class dynamically and invoke the one or two methods necessary to create the documentation.
 *
 * This is a new capability in 1.9.0 in preparation for the Extension Registry and therefore, you should
 * <b>NOTE WELL:</b> At this time, while this class is part of nifi-api, it is still evolving and may change in a non-backward-compatible manner or even be
 * removed from one incremental release to the next. Use at your own risk!
