Module org.apache.jena.dboe.storage
Package org.apache.jena.dboe.storage

Interface StoragePrefixes

All Known Implementing Classes:
StoragePrefixesEmpty, StoragePrefixesSimpleMem
public interface StoragePrefixes
Like PrefixMapping, only for a dataset which can have different prefix maps for different graphs. There is a distinguished name Prefixes.nodeDataset that means the prefixes apply to the dataset as a whole, not a specific graph.
