-    \class Qt3DCore::QFrameAllocator
-    \inmodule Qt3DCore
-    \brief Provides a pool of memory chunks to be used to allocate objects on a per frame basis.
-
-    The memory can be recycled by following frames by calling clear which won't deallocate any memory.
-
-    \note Be really careful when allocating polymorphic types. You must be
-    sure to call deallocate with the subclass type to properly release all
-    memory.
