Detailed Description

Deprecated

Base class for obsolete error-handler callbacks.

This method of handling errors is obsolete. Use a "notice handler" instead.

Warning

Strange things happen when a result object outlives its parent connection. If you register an error handler on a connection, then you must not access the result after destroying the connection. This applies even if you destroy the error handler first!
