Methods (Including Private)

classmethod OnPage() as %Status [ Language = objectscript ]
The OnPage() is called by the CSP dispatcher to generate the page content. For XMLSQL, we loop across the ResultSet and output the contents as XML.
classmethod OnPostHTTP() [ Language = objectscript ]
The OnPostHTTP() is called by the CSP dispatcher after the page content has been sent. We use it here to clean up the ResultSet
classmethod OnPreHTTP() as %Boolean [ Language = objectscript ]
The OnPreHTTP() is called by the CSP dispatcher before the HTTP headers have been sent. Here, we prepare the Dynamic SQL query and set the content type to text/xml.
classmethod PreProcessSQL(sql As %String, ByRef args As %String, mode As %Integer, ByRef xmlmode As %String) as %String [ Language = objectscript ]
Process the XML SQL extras from the SQL statement. The mode is as follows:

  • 0 - Default XML-SQL mode
  • 1 - Oracle XML-SQL mode

classmethod ResolveElementName(expr As %String, element, AssumeName) as %String [ Language = objectscript ]
