public void cancel()
throws XQException
XQExpressionXQExpression. This method can
be used by one thread to cancel an XQExpression, that is being executed
in another thread. If cancellation is not supported or the attempt to
cancel the execution was not successful, the method returns without any
error. If the cancellation is successful, an XQException is
thrown, to indicate that it has been aborted, by executeQuery,
executeCommand or any method accessing the XQResultSequence
returned by executeQuery. If applicable, any open XQResultSequence
and XQResultItem objects will also be implicitly closed in this case.

executeQuery in interface XQExpressionquery - the input query expression as a input stream object.
Cannot be null
XQResultSequence containing the
result of the query execution
XQException - if (1) there are errors when executing the query,

public XQResultSequence executeQuery(Reader query)
throws XQException
XQExpression
executeQuery in interface XQExpressionquery - the input query expression as a reader object.
