パラメータ

dataSource

Data source collection containing data for aggregation.

view

View definition. It is obtained from a view in JSON format using System.Web.Script.Serialization.JavaScriptSerializer.Deserialize.

cancelToken

Enables task cancellation.

progress

Callback function to report progress updates.

戻り値の型

This method supports multi-user thread-safe execution of views on the server. Result of such execution is intended for passing to a client for visualization on the web or elsewhere.

It can execute views over multiple dataSource collections. It maintains a pool of Workspace objects internally to enable that.

Aggregation result is a dictionary mapping keys to values. See a description of keys and values in %C1.PivotEngine.C1PivotEngine.Exec(string, string, System.Collections.Generic.Dictionary<string,object>, System.Threading.CancellationToken)%
