'宣言 Public Shadows Sub Add( _ ByVal item As RecordFilter _ )
public new void Add( RecordFilter item )
Add メソッドは指定した RecordFilter をコレクションに追加します。
注： 指定した RecordFilter と同じ Field または FieldName に関連付けられる RecordFilter が存在する場合は、存在の RecordFilter が削除されます。実際に、このような場合には代替操作を実行します。これは、コレクションが同じフィールドでの複数の RecordFilter オブジェクトの利用を許可していないためです。
