Detailed Description

Allocator class interface for sub-allocating a contiguous memory block into smaller regions of memory.

This class only manages the address creation for the regions – allocation callback functions are used to request the memory from the necessary system or API calls. This class is intended to be used inside of a higher level memory management class that provides thread safety, policy management and API integration for a specific runtime API (eg Vulkan, OpenCL, etc)
