スライサーは以下の手順に基づき、 GeneralSlicerDataクラスと連携して動作します。
データを指定し、新規のGeneralSlicerDataを作成します。
カスタムスライサーを新規作成し、GeneralSlicerDataに接続します。.
GeneralSlicerDataから列データを取得し、スライサーのUIを作成します。
UIイベントに応答し、GeneralSlicerDataの doFilterメソッドを呼び出します。
GeneralSlicerDataからフィルタ結果を取得し、スライサーのUIを更新します。
以下のAPIは簡潔な処理の構築に役立ちます。
getData: 特定の列の全データを取得します。
getExclusiveData: 排他データ（重複しないデータ）を取得します。
doFilter: 列をフィルタリングします。
doUnfilter: フィルタリング情報を消去します。
attachListener: リスナーをGeneralSlicerDataに接続します。
detachListener: リスナーとGeneralSlicerDataの接続を解除します。
onFiltered: フィルタリングの発生に応じて実行されるイベントです。
