[jira] [Updated] (XERCESJ-1449) Validation of schema type unions
are relatively slow due to use of exceptions.
[ https://issues.apache.org/jira/browse/XERCESJ-1449?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Chris Simmons updated XERCESJ-1449:
-----------------------------------
Description:
I'll shortly attach some example code which shows that validating
2010-01-01T00:00:00.000Z
against the union (date, dateTime) is slower by a factor of three than validating against (dateTime, date).
This appears to be because if validation fails against the first member of the union then an exception is thrown.
It would therefore be quicker to change the simple type validation to allow an error handler of some sort to be passed in so that union types will not have to use exception handling when validating.
