LongRangeSource

@Target(allowedTargets = [AnnotationTarget.VALUE_PARAMETER])

@SourceProvider(value = LongRangeDataProvider::class)

annotation class LongRangeSource(val min: Long, val max: Long, val increment: Long = 1, val ascending: Boolean = true)

Annotation to indicate that the annotated long parameter should be populated with a long range from min to max with an increment step in the ascending direction.
