Method Detail

create

public static Query create(java.lang.String queryString)

Create a SPARQL query from the given string.

Parameters:

queryString - The query string

Throws:

QueryException - Thrown when a parse error occurs

create

public static Query create(java.lang.String queryString,
                           Syntax syntax)

create

public static Query create(java.lang.String queryString,
                           java.lang.String baseURI)

Create a query from the given string by calling the parser.

Parameters:

queryString - The query string

baseURI - Base URI

Throws:

QueryException - Thrown when a parse error occurs

create

public static Query create(java.lang.String queryString,
                           java.lang.String baseURI,
                           Syntax syntax)

Create a query from the given string by calling the parser.

Parameters:

queryString - The query string

baseURI - Base URI

syntax - Syntax

Throws:

QueryException - Thrown when a parse error occurs

create

public static Query create()

Make a query - no parsing done

make

public static Query make()

Make a query - no parsing done - old name: create() preferred.

create

public static Query create(Query originalQuery)

Make a query from another one by deep copy (a clone). The returned query will be .equals to the original. The returned query can be mutated without changing the original (at which point it will stop being .equals)

Parameters:

originalQuery - The query to clone.

parse

public static Query parse(Query query,
                          java.lang.String queryString,
                          java.lang.String baseURI,
                          Syntax syntaxURI)

Parse a query from the given string by calling the parser.

Parameters:

query - Existing, uninitialized query

queryString - The query string

baseURI - URI for relative URI expansion

syntaxURI - URI for the syntax

Throws:

QueryException - Thrown when a parse error occurs
