Interface RDFDataSource

All Known Subinterfaces:
RDFDataSourceWrapper<T>
All Known Implementing Classes:
DecoratedRDFDataSource, RDFDataSourceAdapter, RdfDataSourceMulti, RDFDataSourceOverDataset, RDFDataSources.RDFDataSourceOverSparqlQueryConnection, RdfDataSourceWithBnodeRewrite, RdfDataSourceWithLocalCache, RdfDataSourceWithLocalCacheRework, RdfDataSourceWithLocalLateral, RdfDataSourceWithSimpleCache, RDFDataSourceWrapperBase, RdfDataSourceWrapperWithRewrite
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface RDFDataSource
A factory/supplier of RDFConnection instances. Similar to a JDBC DataSource. This interface does not provide resource management, i.e. a close() method. It should only be used as follows: (a) As a lambda in conjunction with RDFDataEngines#of(RDFDataSource, AutoCloseable) (b) in consuming code that does not need resource management Prefer RDFEngine whenever resources may need to be closed.

      @Deprecated default QueryExecutionFactory asQef()
      Deprecated.
      Return a connection-less QueryExecutionFactory view of this data source. Every QueryExecution created with the returned factory will obtain a fresh connection using getConnection() upon execution. The connection is closed when closing the QueryExecution. Consequently, the use of connection pooling is recommended in cases where calling getConnection() is expensive. The behavior of AutoCloseable.close() is implementation dependent. By default it is a no-op but it may close the data source.
