ModelDatabaseConditionQuery class

Base class for creating queries to access the database.

If a list exists on CollectionModelPath.query, only the conditions specified there are queryable.

If you use FirebaseDataConnect, this is required; if you use Firestore, RealtimeDatabase, or LocalDatabase, it is not necessary.

データベースへのアクセスを行うクエリを作成するためのベースクラスです。

CollectionModelPath.query上のでリストが存在している場合、そこで指定されている条件のみがクエリ可能となります。

FirebaseDataConnectを利用する場合、こちらの指定は必須となります。FirestoreやRealtimeDatabase、LocalDatabaseを利用する場合は特に必要ありません。
