| 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. |
