A delegate class method that will be executed before a record is copied using the copy set or copy selected function. All xataface copies are shallow which means that related records are not copied by default. If you want a more complex copy function for a table you can implement functionality in this hook.
Available since version 1.3
function beforeCopy( Dataface_Record $original, array $values);
$original - The original record that is to be copied.
$values - Associative array of values that are meant to be changed in the copy. Keys correspond with column names.
Either return nothing or you may return a PEAR_Error object to indicate that an error occurred with the copy.
afterCopy - The afterCopy hook that can be implemented in the delegate class to run just after a record is copied.
