UIPermission.IsSubsetOf メソッド

2008-03-28

現在のアクセス許可が、指定したアクセス許可のサブセットかどうかを判断します。

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

パラメータ

target
サブセットの関係を調べるアクセス許可。このアクセス許可は、現在のアクセス許可と同じ型である必要があります。

戻り値

現在のアクセス許可が、指定したアクセス許可のサブセットである場合は true 。それ以外の場合は false 。

実装

IPermission.IsSubsetOf

例外

例外の種類	条件
ArgumentException	target パラメータが null 参照 (Visual Basic では Nothing) ではなく、現在のアクセス許可と同じ型でもありません。

解説

現在のアクセス許可で成功したすべての要求が指定したアクセス許可でも成功する場合、その現在のアクセス許可は、その指定したアクセス許可のサブセットです。つまり、指定したアクセス許可には、サブセット内に含まれているアクセス許可が必ず含まれます。 IsSubsetOf で true を返すためには、現在のアクセス許可の UIPermissionWindow 値と UIPermissionClipboard 値の両方が、指定したアクセス許可の値以下である必要があります。
