Class XQQueryException

  • All Implemented Interfaces:
    java.io.Serializable
    Direct Known Subclasses:
    XQCancelledException

    public class XQQueryException
    extends XQException
    An exception that provides information on errors occurring during the evaluation of an xquery.

    Each XQQueryException provides several kinds of optional information, in addition to the properties inherited from XQException:
    • an error code. This QName identifies the error according to the standard as described in Appendix F, XQuery 1.0: An XML Query language, Appendix C, XQuery 1.0 and XPath 2.0 Functions and Operators, and and its associated specifications; implementation-defined errors may be raised.
    • a position. This identifies the character position of the failing expression in the query text. This is a 0 based position. -1 if unknown.
    • the line number in the query string where the error occured. Line numbering starts at 1. -1 if unknown
    • the column number in the query string where the error occured. Column numbering starts at 1. -1 if unknown
    • the module uri. This identifies the module in which the error occurred, null when the error is located in the main module.
    • the XQuery error object of this exception. This is the $error-object argument specified through the fn:error() function. May be null if not specified.
    • the XQuery stack trace. This provides additional dynamic information where the exception occurred in the XQuery expression.
