Dynamic Hook docs missing critical information

The following page is missing critical information:
http://orientdb.com/docs/last/Dynamic-Hooks.html

Java static methods

Dynamic Hooks can call:

• Functions, written in SQL, Javascript or any language supported by OrientDB and JVM
• Java static methods
  There isn't any mention of how a dynamic hook can call a java static method.

Delete hook

A section should be added describing how to delete a hook. For example:

To delete a hook, set the event value to null
e.g. ALTER CLASS Invoice CUSTOM onAfterCreate=null

Variables available inside the hook

Add a description for all of the variables that are provided inside of a hook.
For example:

In a javascript hook, a var called "doc" is provided that represents the current document.

Describing a few common use cases would be helpful such

1. Retrieving old vs new values of a doc
2. Getting the correct OrientBaseGraph from the document

For example

var db = doc.getDatabase();
var orientBaseGraph =(db.getTransaction().isActive())
    ?new com.tinkerpop.blueprints.impls.orient.OrientGraph(db)
    :new com.tinkerpop.blueprints.impls.orient.OrientGraphNoTx(db);
