Annotation Interface DisallowRunOnce

@Documented @Target(TYPE) @Retention(RUNTIME) @Inherited public @interface DisallowRunOnce

Marker annotation a Processor implementation can use to indicate that the Processor is not designed in such a way that the 'Run Once' capability would function.

Some processors need many execution cycles to perform any meaningful work and as such the user triggering a 'Run Once' execution will likely result in no response or outcome at all.
