Provides helper macros to implement singleton objects:
|
|
|
|
this mean one instance in one thread
|
|
- __DeclareThreadSingleton put this into class declaration.
|
|
- __ImplementThreadSingleton put this into the implemention file.
|
|
- __ConstructThreadSingleton put this into the constructor
|
|
- __DestructThreadSingleton put this into the destructor
|
|
|
|
this mean one instance in one image
|
|
- __DeclareImageSingleton put this into class declaration. one instance in one Image
|
|
- __ImplementImageSingleton put this into the implemention file. one instance in one Image
|
|
- __ConstructImageInterfaceSingleton put this into the constructor
|
|
- __DestructImageInterfaceSingleton put this into the destructor
|
|
|
|
Get a pointer to a singleton object using the static Instance() method:
|
|
|
|
Core::Server* coreServer = Core::Server::Instance();
