MemoryAllocator¶

MemoryAllocator is an abstraction of memory allocators that TaskMemoryManager uses to allocate and release memory.

MemoryAllocator creates the available MemoryAllocators to be available under the names HEAP and UNSAFE.

A MemoryAllocator to use is selected when MemoryManager is created (based on MemoryMode).
