Interface StoragePrefixes

All Known Implementing Classes:

StoragePrefixesEmpty, StoragePrefixesMem

public interface StoragePrefixes

Like PrefixMapping, only for a dataset which can have different prefix maps for different graphs. There is a distinguished name nodeDataset that means the prefixes apply to the dataset as a whole, not a specific graph.
