tinyj-lazy build status

A thread and exception safe implementation of lazy (aka on-demand) value initialization.

Features:

  • Initialization is guaranteed to run only once in multi-threaded scenarios as well in case of raised exceptions
  • The initializer is released after initialization so it can be collected by the garbage collector. This is still true if initialization fails.
  • Exception raised during initialization are propagated in the same thread (this is important if a InterruptedException for that thread is raised during initialization)
  • Exceptions raised during initialization are kept for later inspection/logging
