All Implemented Interfaces:
Subset
Direct Known Subclasses:
NameKeyedSubset, OTSubset, Type1Subset
public class SubsetDefaultImpl extends Object implements Subset
A default implementation for the Subset interface.

This implementation is suitable for subclassing, if specific behaviour is needed beyond the correspondance between subset and full gids.
