Class ElfImage

java.lang.Object
  lib.unwind.ElfImage

public class ElfImage
extends Object

An object that, eventually, releases its underlying mmaped [elf] data during a garbage collect. Since the garbage collect will, typically, occure after libunwind's step has finished with the data this operation is safe. However, there is the real possibility of the GC occuring early, unmapping the data causing an NPE.
