The Ghost in the Virtual Machine: A Reference to References

Java: Trends
Location: A107/108
Average rating: ****.
(4.29, 7 ratings)

Ever wondered whether you should use a weak reference or a phantom reference? If you answered “yes” or “phantom who?,” this is the talk for you. We’ll cover:

  • The java.lang.ref API
  • Its failure modes
  • Reference handling patterns, APIs, and best practices
  • MapMaker: a concurrent map builder with support for strong, soft, or weak keys and/or values
    and more.

Walk in with a working knowledge of the language, and walk out an expert in references, referents, reclamation and other garbage collection necromancy.
