Class MMFBytez

java.lang.Object

org.nustaq.offheap.bytez.malloc.MallocBytez

org.nustaq.offheap.bytez.malloc.MMFBytez

All Implemented Interfaces:

ByteSource, Bytez

public class MMFBytez
extends MallocBytez

Bytez allocated inside a memory mapped file. Some Mmap file stuff handling is copied from OpenHFT library (too big to depend on for fst), a great tool for all kind of binary/low level java stuff. Check it out at github.
