Converts from a list of classes into a map that contains the record id as the key and the Constructor in the value part of the map. It does this by using reflection to look up the RECORD_ID field then using reflection again to find a reference to the constructor.

Parameters:

recClasses - The records to convert

Returns:

The map containing the id/constructor pairs.

isContainer

public static boolean isContainer(short options,
                                  short recordId)
