Modeling Concurrency
We’ll start with a simple example and build a concurrent model of an everyday scene. Imagine I see four people out for a walk. There are two dogs and a large number of rabbits. The people are talking to each other, and the dogs want to chase the rabbits.
To simulate this in Erlang, we’d make four modules called
person
, dog
, rabbit
, and
world
. The code for person
would be in a file
called person.erl
and might look something like this:
| -module(person). |
| -export([init/1]). |
| |
| init(Name) -> ... |
The first line, -module(person).
, says that this file
contains code for the module called person
. This should
be the same as the filename (excluding the .erl
filename
extension). The module name must start with a small letter. ...
