Babble::DataSource - Base data source class for Babble

DESCRIPTION

Top

Babble::DataSource is a base class, a class which should never ever be used directly by applications (as it does nothing useful).

This class is merely provided to be a base to inherit from. All descendants must implement at least the methods this class implements.

METHODS

Top

The following methods are required to be implemented by all Babble::DataSource descendants:

new(%params)

Obviously, this creates a new object. The new object should in all cases, call SUPER::new, as to get their params stored. Then, it can go an interpret them as it sees fit.

collect($babble)

This method does whatever is necessary to collect the data from the source, and then return a Babble::Document::Collection object.

The only paramater passed, is a Babble object reference.
