XmlSchemaSimpleType クラス

[アーティクル]
03/28/2008

クラスは、テキストだけの内容を持つ属性または要素の値に関する情報や制約を決定する単純型を定義します。W3C (World Wide Web Consortium) simpleType 要素を表します。

この型のすべてのメンバの一覧については、XmlSchemaSimpleType メンバを参照してください。

public __gc class XmlSchemaSimpleType : public XmlSchemaType
[JScript]
public class XmlSchemaSimpleType extends XmlSchemaType

スレッドセーフ

この型の public static (Visual Basicでは Shared) のすべてのメンバは、マルチスレッド操作で安全に使用できます。インスタンスのメンバの場合は、スレッドセーフであるとは限りません。

解説

単純型は、既存の単純型 (組み込みデータ型および派生単純型) から派生して定義されます。単純型は、要素を格納できず、属性を持つこともできません。
