本文整理了Java中javax.xml.xquery.XQException类的一些代码示例，展示了XQException类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。XQException类的具体详情如下：
包路径：javax.xml.xquery.XQException
类名称：XQException

XQException介绍

[英]An exception that provides information on XQJ, XQuery or other errors reported by an XQJ implementation.

Each XQException provides several kinds of information:

  • a string describing the error. This is used as the Java Exception message, available via the method getMessage.
  • the cause of the error. This is used as the Java Exception cause, available via the method getCause.
  • the vendor code identifying the error. Available via the method getVendorCode. Refer to the vendor documentation which specific codes can be returned.
  • a chain of XQException objects. If more than one error occurred the exceptions are referenced via this chain.

Note that XQException has a subclass XQQueryException providing more detailed information about errors that occurred during the processing of a query. An implementation throws a base XQException when an error occurs in the XQJ implementation. Further, implementations are encouraged to use the more detailed XQQueryException in case of an error reported by the XQuery engine.

It is possible that during the processing of a query that one or more errors could occur, each with their own potential causal relationship. This means that when an XQJ application catches an XQException, there is a possibility that there may be additional XQException objects chained to the original thrown XQException. To access the additional chained XQException objects, an application would recursively invoke getNextException until a null value is returned.

An XQException may have a causal relationship, which consists of one or more Throwable instances which caused the XQException to be thrown. The application may recursively call the method getCause, until a null value is returned, to navigate the chain of causes.
[中]提供有关XQJ、XQuery或XQJ实现报告的其他错误的信息的异常。
每个XQException都提供了几种信息：
*描述错误的字符串。这被用作Java异常消息，可通过[$1$]方法获得。
*错误的原因。这被用作Java异常原因，可通过[$2$]方法获得。
*识别错误的供应商代码。可通过[$3$]方法获得。请参阅供应商文件，以了解可以返回哪些特定代码。
*XQException对象链。如果发生了多个错误，则通过此链引用异常。
注意XQException有一个子类XQQueryException，它提供了有关查询处理过程中发生的错误的更详细信息。当XQJ实现中发生错误时，实现抛出一个基XQException。此外，如果XQuery引擎报告错误，建议实现使用更详细的XQQueryException。
在查询处理过程中，可能会出现一个或多个错误，每个错误都有其潜在的因果关系。这意味着，当XQJ应用程序捕捉到XQException时，可能会有额外的XQException对象链接到原始抛出的XQException。要访问额外的链接XQException对象，应用程序将递归调用getNextException，直到返回null值。
XQException可能有因果关系，由一个或多个Throwable实例组成，这些实例导致XQException被抛出。应用程序可能会递归调用方法getCause，直到返回null值，以浏览原因链。
