Hi everyone,

I develop a Xbase-based DSL in which the developer can describe certain types with fields. At some point in the model inferrer, I want to check whether a field is of type "byte[]" - an array of primitive byte. I struggle a little bit with this check. I currently have the following:
if (member.type.isArray) {
	val componentType = (member.type as JvmGenericArrayTypeReference).componentType
	if (componentType.isPrimitive) {
		val primitiveType = componentType.type as JvmPrimitiveType
		if (primitiveType.simpleName == 'byte') {
			field.annotations += jpa.lob.annotationRef
		}
	}
}


This works. However, both type casts and the compare with the String "byte" just seem wrong to me. Is there a better way to do this?

Thanks a lot in advance.
