fromMap static method

DynamicMap fromMap(DynamicMap value)

Performs the process of converting data read from the server.

Pass the data read from the server to value.

The converted data is passed to the return value.

サーバーから読み取られたデータを変換する処理を実行します。

valueにサーバーから読み取られたデータを渡します。

戻り値に変換後のデータが渡されます。
