Method Detail

create

public static TripleStore create()

Create a Triplestore database using the default implementation.

Returns:

a Triplestore based on the default implementation

copy

public static TripleStore copy(TripleStore source)

Crate a Triplestore that is a copy of the given Triplestore. Copied Triplestore will be based on the same implementation of the source Triplestore.

Parameters:

source - the source Triplestore

Returns:

a new Triplestore that is a copy of the source Triplestore

create

public static TripleStore create(String impl)

Create a Triplestore database using the given implementation.

Parameters:

impl - the name of the Triplestore implementation that must be used

Returns:

a Triplestore based on the given implementation

allImplementations

public static List<String> allImplementations()

List all Triplestore implementations available.

Returns:

a list with the names of all available Triplestore implementations

implementationsWorkingWithNestedGraphClauses

public static List<String> implementationsWorkingWithNestedGraphClauses()

List all available Triplestore implementations that support nested graph clauses in SPARQL queries.

Returns:

a list with the names of all available Triplestore implementations supporting nested graph clauses in SPARQL queries

implementationsBadNestedGraphClauses

public static List<String> implementationsBadNestedGraphClauses()

List all available Triplestore implementations that have problems with nested graph clauses in SPARQL queries.

Returns:

a list with the names of all available Triplestore implementations that have problems with nested graph clauses in SPARQL queries

onlyDefaultImplementation

public static List<String> onlyDefaultImplementation()

Get a list containing only the name of the default Triplestore implementation.

Returns:

a list with the name of the default Triplestore implementation

defaultImplementation

public static String defaultImplementation()

Get the name of the default Triplestore implementation.

Returns:

the name of the default Triplestore implementation
