3 | @brief Definition of the Factory and the BaseFactory class. |
---|
4 | |
---|
5 | The Factory is a singleton, containing two maps to map either the name or the network ID |
---|
6 | of a class with the corresponding Identifier. |
---|
7 | |
---|
8 | Usage: |
---|
9 | ID(classname) or ID(networkID) returns the corresponding Identifier. |
---|
10 | |
---|
11 | |
---|
12 | BaseObject is the parent of ClassFactory which is defined in ClassFactory.h. |
---|
13 | It can't be defined in ClassFactory.h, because of circular dependencies. |
