XQItemType介绍

[英]The XQItemType interface represents an item type as defined in XQuery 1.0: An XML Query language.
The XQItemType extends the XQSequenceType but restricts the occurrance indicator to be exactly one. This derivation allows passing an item type wherever a sequence type is expected, but not the other way. The XQItemType interface contains methods to represent information about the following aspects of an item type:

• The kind of the item - one of XQITEMKIND_* constants
• The base type of the item - one of the XQBASETYPE_* constants. For atomic types this is the closest matching built-in XML Schema type, for element and attributes the closest matching built-in XML Schema type this node is based on.
• Name of the node, if any
• Type name, if any. If present, then also whether the typename is an anonymous type
• XML Schema URI associated with the type, if any
• The nillability characteristics, if any
  An instance of the XQItemType is a standalone object that is independant of the XQConnection and any XQuery static or dynamic context.
  [中]XQItemType接口表示XQuery 1.0: An XML Query language中定义的项类型。
  XQItemType扩展了XQSequenceType，但将发生指示器限制为正好一个。这种派生允许在任何需要序列类型的地方传递项类型，但不能以相反的方式传递。XQItemType界面包含表示项目类型以下方面信息的方法：
  *项目的类型-XQITEMKIND_*常量之一
  *项目的基本类型，XQBASETYPE_*常量之一。对于原子类型，这是最匹配的内置XML模式类型；对于元素和属性，这是该节点基于的最匹配的内置XML模式类型。
  *节点的名称（如果有）
  *键入名称（如果有）。如果存在，还需要检查typename是否为匿名类型
  *与类型关联的XML架构URI（如果有）
  *可零性特征（如有）
  XQItemType的实例是一个独立的对象，它独立于XQConnection和任何XQuery静态或动态上下文。
