Instead of letting individual objects find or create their own instances of the objects with which they collaborate, or making them go through a Service Locator, we let an external agent find these objects and then pass them in to the individual instances instead.
This way, dependencies are "injected" into these collaborators instead of being hard-wired into the code.
Injectors pass in information about collaborators using constructors and/or setters.
