# IMPORTANT: Entries of enum class ORM_PolicyRuleStateEnum should be named as in
#            the proto files removing the prefixes. For example, proto item
#            PolicyRuleStateEnum.POLICY_INSERTED should be declared as INSERTED.
#            In this case, since the entries in the proto enum have a different prefix
#            than that specified in class ORM_PolicyRuleStateEnum, we force the prefix
#            using argument grpc_enum_prefix. If item name does not match, automatic
#            mapping of proto enums to database enums will fail.
