REGARDING EXTRACTING OF PROPERTIES

Hi,

I am fairly new to ADOBE DAY CQ.. I want to extract properties of a particular node...

I am using the following code....

Node aName= session.getNode(absPath);

String propertyName= aName.getPRoperty("Name").getValue().getString();

I am aware that there is an abstract class named ABSTRACTSESSION which extends the OBJECT class and implements SESSION interface...

and getNode is a method defined in the class ABSTRACTSESSION...

What i want to know is "is there any class which extends the ABSTRACTSESSION??? Where can i find material to read about the session management in cq?

Regards and Thanks in advance,

Heidi.
