setAsyncResult メソッド

非同期関数の評価結果をCalcEngineに設定します。CalcEngineはこの値を使用して、この非同期関数を含むセルとすべての依存セルを再計算します。

シンタックス

Javascript (Usage)
Javascript (Specification)

var instance = new GC.Spread.CalcEngine.AsyncEvaluateContext(context);
var returnValue; // Type: any
returnValue = instance.setAsyncResult(value);

function setAsyncResult( 
   value : Object
) : any;

パラメータ

value: 非同期関数の評価結果。

使用例

次のサンプルコードは、refresh数式を使用します。
