OOP to me means only messaging, local retention and protection and
hiding of state-process, and extreme late-binding of all things.
What is local retention? Can someone explain with an example from any programming language (e.g. Java,Scala, Lisp, Haskell)
Local retention refers to fraction of larvae spawned from Patch 1 (X) that also recruit back into Patch 1 (Y). Self-recruitment refers to the fraction of recruitment into Patch 1 (Z) composed of recruits spawned from patch 1 (Y).
A retention program is a specific set of activities or initiatives a company takes to retain its customers. A retention program helps to increase customer value and bring customers into doing repeat business with the company.
To parse the sentence correctly, "OOP to me means only
So I think "local retention ... of state-process" just means that state is kept locally within objects.
