A337 Alloy Connecting Link in G80

A hook is some easy way to extend or replace a certain part of the source by your own methods. They are often used for providing pre- and post-processing userfunctions in the core as well as giving control totally to a method provided by some extension author. 
The big advantage of using a hook instead of the older X-Class mechanism is the ability to enable more than one extension to extend the same class or method. This has been discussed in the developer mailinglist for some time and is also explained in the TYPO3 Core APIs document. 
The drawback is, that a hook has to exist before you can use it. So if you are in a situation in which you would like to extend a core or extension's functionality, just ask the source's author to provide a hook for you in the next release.
