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.
