Add "allocator" parameter for STL

[ven]

Ogre allows replace allocators for allocate objects (using new and delete), but does not allows replace the allocators for stl containers (like stl::vector, stl::string, std::ostringstream ) that are also necessary.

All you have to do - it is added to all typedef stl containers "allocator" parameter, like

Code: Select all

typedef std::vector<SubMesh*, allocator<SubMesh*> > SubMeshList;
// instead
typedef std::vector<SubMesh*> SubMeshList;

and set in OgreConfig.h

Code: Select all

typedef std::allocator allocator;

This change does not affect users, but increases flexibility. This allows use of efficient allocators everywhere.

Unless I've misunderstood it all, we already have that:

Yes, that's exactly what I mean.
Sorry for the repeat.
