abstract class AbstractPropertyGraphDataSource extends CAPSPropertyGraphDataSource

Abstract data source implementation that takes care of caching graph names and schemas.

It automatically creates initializes a ScanGraphs an only requires the implementor to provider simpler methods for reading/writing files and tables.
