Allocators

Allocator helpers are used in the command buffer objects as a means to allocate memory for the latter. Currently, only a pool allocator is implemented.

Common interface

In SecondaryCommandBuffer.h, the helper classes related to the selected allocator type are aliased as the following:

• SecondaryCommandMemoryAllocator

  • This is the main allocator object used in the allocator helper class. It is used as a type for some of the allocator helper's public functions.

• SecondaryCommandBlockPool

  • This allocator is used in SecondaryCommandBuffer.

• SecondaryCommandBlockAllocator

  • This allocator is defined in CommandBufferHelperCommon, and by extension, is used in its derived helper classes for render pass and outside render pass command buffer helpers.
