h2. Brief description of some of the core code components

* *leginondata.py* and *event.py* contain the definitions of all classes of data that are passed around between nodes and/or stored in the database.

* *node.py* defines *Node*, the base class for all nodes.  You will find a lot of the basic node functionality here, like passing events, storing user preferences, etc.

h2. Brief description of some of the nodes

* *targetwatcher.py* defines the class *TargetWatcher* which includes basic functionality for processing targets that were produced by another node.  The input is target list, which is handled by the *processTargetListData* method.  This method loops over the targets, calling *processTargetData* on each one.  The *processTargetData* method must be defined in a subclass.

* *acquisition.py* defines the *Acquisition* class, which is a subclass of *TargetWatcher*.  It defines the *processTargetData* function such that an acquisition sequence happens at each target.  More info, see: [[acquisition.py]]
