- Method Detail
  - connectDataset
```
public static Dataset connectDataset(org.apache.jena.dboe.base.file.Location location)
```
    Create or connect to a TDB2-backed dataset
  - connectDataset
```
public static Dataset connectDataset(java.lang.String location)
```
    Create or connect to a TDB2-backed dataset
  - createDataset
```
public static 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 Dataset assembleDataset(java.lang.String assemblerFile)
```
    Read the file and assemble a dataset
  - isTDB2
```
public static boolean isTDB2(Dataset dataset)
```
    Test whether a dataset is backed by TDB or not.
  - location
```
public static org.apache.jena.dboe.base.file.Location location(Dataset dataset)
```
    Return the location of a dataset if it is backed by TDB, else null
