Method Detail

prepareBooleanQuery

public BooleanQuery prepareBooleanQuery(QueryLanguage ql,
                                        String query,
                                        String baseURI)
                                 throws MalformedQueryException,
                                        RepositoryException

Description copied from interface: RepositoryConnection

Prepares queries that return true or false.

Specified by:

prepareBooleanQuery in interface RepositoryConnection

Overrides:

prepareBooleanQuery in class RepositoryConnectionWrapper

Parameters:

ql - The query language in which the query is formulated.

query - The query string.

baseURI - The base URI to resolve any relative URIs that are in the query against, can be null if the query does not contain any relative URIs.

Returns:

a BooleanQuery ready to be evaluated on this RepositoryConnection.

Throws:

MalformedQueryException - If the supplied query is malformed.

RepositoryException

prepareGraphQuery

public GraphQuery prepareGraphQuery(QueryLanguage ql,
                                    String query,
                                    String baseURI)
                             throws MalformedQueryException,
                                    RepositoryException

Description copied from interface: RepositoryConnection

Prepares queries that produce RDF graphs.

Specified by:

prepareGraphQuery in interface RepositoryConnection

Overrides:

prepareGraphQuery in class RepositoryConnectionWrapper

Parameters:

ql - The query language in which the query is formulated.

query - The query string.

baseURI - The base URI to resolve any relative URIs that are in the query against, can be null if the query does not contain any relative URIs.

Returns:

a GraphQuery ready to be evaluated on this RepositoryConnection.

Throws:

MalformedQueryException - If the supplied query is malformed.

RepositoryException

prepareQuery

public Query prepareQuery(QueryLanguage ql,
                          String query,
                          String baseURI)
                   throws MalformedQueryException,
                          RepositoryException

Description copied from interface: RepositoryConnection

Prepares a query for evaluation on this repository (optional operation).

If you already know the type of query, using the more specific RepositoryConnection.prepareTupleQuery(java.lang.String), RepositoryConnection.prepareGraphQuery(java.lang.String) or RepositoryConnection.prepareBooleanQuery(java.lang.String) is likely to be more efficient.

Specified by:

prepareQuery in interface RepositoryConnection

Overrides:

prepareQuery in class RepositoryConnectionWrapper

Parameters:

ql - The query language in which the query is formulated.

query - The query string.

baseURI - The base URI to resolve any relative URIs that are in the query against, can be null if the query does not contain any relative URIs.

Returns:

A query ready to be evaluated on this repository.

Throws:

MalformedQueryException - If the supplied query is malformed.

RepositoryException

prepareTupleQuery

public TupleQuery prepareTupleQuery(QueryLanguage ql,
                                    String query,
                                    String baseURI)
                             throws MalformedQueryException,
                                    RepositoryException

Description copied from interface: RepositoryConnection

Prepares a query that produces sets of value tuples.

Specified by:

prepareTupleQuery in interface RepositoryConnection

Overrides:

prepareTupleQuery in class RepositoryConnectionWrapper

Parameters:

ql - The query language in which the query is formulated.

query - The query string.

baseURI - The base URI to resolve any relative URIs that are in the query against, can be null if the query does not contain any relative URIs.

Returns:

a TupleQuery ready to be evaluated on this RepositoryConnection.

Throws:

MalformedQueryException - If the supplied query is malformed.
