DelayedLazyVal

class DelayedLazyVal[T] extends AnyRef

A DelayedLazyVal is a wrapper for lengthy computations which have a valid partially computed result.

The first argument is a function for obtaining the result at any given point in time, and the second is the lengthy computation. Once the computation is complete, the apply method will stop recalculating it and return a fixed value from that point forward.
