UIPermission.Union メソッド

アクセス許可と指定したアクセス許可の和集合を表すアクセス許可を作成します。

Overrides Public Function Union( _
   ByVal target As IPermission _) As IPermission Implements IPermission.Union
[C#]
public override IPermission Union(IPermissiontarget);
[C++]
public: IPermission* Union(IPermission* target);
[JScript]
public override function Union(
   target : IPermission) : IPermission;

パラメータ

• target
  現在のアクセス許可と和集合を持つアクセス許可。これは、現在のアクセス許可と同じ型であることが必要です。

戻り値

現在のアクセス許可と指定したアクセス許可の和集合を表す新しいアクセス許可。

実装

IPermission.Union

例外

解説

Union を呼び出すと、現在のアクセス許可と指定したアクセス許可の両方が表す操作をすべて表すアクセス許可が作成されます。具体的には、このアクセス許可は、現在のアクセス許可と指定されたアクセス許可の値の UIPermissionWindow と UIPermissionClipboard の最大許容値を表します。
