Detailed Description

template<typename BaseClassType, typename UniqueIdType>
class glotzutil::ObjectFactory< BaseClassType, UniqueIdType >

a generic object factory

Author:

Aaron Keys

Note:

This code was taken more or less verbatim from http://www.gamedev.net/reference/articles/article2097.asp .

When reading serialized data from a file, there comes a time when we must create a given object based on a string that was parsed. This is not particularly easy to do without writing large one or more large swich() statements that must appended every time we generate a new class. The ObjectFactory allows us to solve this problem by registering our new class with the factory at run time, allowing us to dynamically create objects in a non-invasive way.
