Method Detail

createDatasetGraph

@Deprecated
public static org.apache.jena.sparql.core.DatasetGraph createDatasetGraph(org.apache.jena.dboe.base.file.Location location)

Deprecated. Use DatabaseMgr.connectDatasetGraph(Location)

createDataset

@Deprecated
public static org.apache.jena.query.Dataset createDataset(org.apache.jena.dboe.base.file.Location location)

Deprecated. Use connectDataset(Location)

connectDataset

public static org.apache.jena.query.Dataset connectDataset(org.apache.jena.dboe.base.file.Location location)

Create or connect to a TDB2-backed dataset

createDatasetGraph

@Deprecated
public static org.apache.jena.sparql.core.DatasetGraph createDatasetGraph(String location)

Deprecated. Use DatabaseMgr.connectDatasetGraph(String)

createDataset

@Deprecated
public static org.apache.jena.query.Dataset createDataset(String location)

Deprecated. Use connectDataset(String)

connectDataset

public static org.apache.jena.query.Dataset connectDataset(String location)

Create or connect to a TDB2-backed dataset

createDataset

public static org.apache.jena.query.Dataset createDataset()

Create an in-memory TDB2-backed dataset (for testing). In-memory TDB2 datasets are use a simple simulation of disk I/O to give exact semantics, which is useful to create tests that run fast where setup and teardown of datasets can be the major cost.

In-memory TDB2 datasets are not designed to scale, nor provide efficient execution for applications for long-term use.

assembleDataset

public static org.apache.jena.query.Dataset assembleDataset(String assemblerFile)

Read the file and assemble a dataset

isBackedByTDB

public static boolean isBackedByTDB(org.apache.jena.query.Dataset dataset)

Deprecated. Use {#isTDB2}

Test whether a dataset is backed by TDB or not.

isTDB2

public static boolean isTDB2(org.apache.jena.query.Dataset dataset)

Test whether a dataset is backed by TDB or not.

location

public static org.apache.jena.dboe.base.file.Location location(org.apache.jena.query.Dataset dataset)

Return the location of a dataset if it is backed by TDB, else null
