public class XQStackTraceElement
This class represents a frame in a stack trace, akin to the
java.lang.StackTraceElement
but for XQuery callstacks
instead of Java.

public XQStackTraceElement(String moduleURI, int line, int column, int position, QName function, XQStackTraceVariable[] variables)
XQStackTraceElement
object representing
a frame in a stack trace.
moduleURI
- the module URI containing the execution point representing
the stack trace element. null
when it is the main
module or when the module is unknownline
- the line number in the query string where the error occured.
Line numbering starts at 1
. -1
if unknowncolumn
- the column number in the query string where the error occured.
Column numbering starts at 1
. -1
if unknownposition
- the position in the query string where the error occured. This
is a 0
based position. -1 if unknownfunction
- the QName
of the function in which the exception occurred,
or null
if it occurred outside an enclosing functionvariables
- the variables in scope at this execution point,
or null
if no variable value retrieval is possible
