All Implemented Interfaces:

MemoryManager<ByteBufferWrapper>, WrapperAware<ByteBufferWrapper>

public class SlabMemoryManagerImpl
extends SlabMemoryManagerBase

A simple non-pooled implementation of an Allocator. It creates a Slab whenever the current Slab is exhausted, and relies on the garbage collector to recover the space. Generally this should only be used with BufferType HEAP.
