Class StripedExt

  • public class StripedExt
extends java.lang.Object
    Here we extend Striped to support creating fair reentrant locks. We use reflection to invoke CompactStriped(int, Supplier) and provide a supplier that creates a fair lock. This is clearly a hack, but seems better than the alternative of A) trying to find another library that supports this or B) re-implementing striped locking ourselves.
