"designing a thread safe class" Code Answer


the easiest and most foolproof way of making a class thread safe is to make it immutable. the beauty of it is that you don't ever have to bother with locking again.

recipe: make all instance variables readonly in c# (final in java).

  • an immutable object, once created and initialized in the constructor, cannot change.
  • an immutable object is thread safe. period.
  • this is not the same as having a class with only constants.
  • for mutable parts of your system, you still need to account for and handle locking/synchronization property. this is one reason to write immutable classes in the first place.
