DESCRIPTION
    This class represents queries of various syntaxes over an
    RDF::Redland::Model returning a sequence of results that (currently)
    bind variable names to RDF::Redland::Node values.

CONSTRUCTORS
    new QUERY-STRING [BASE-URI [QUERY-LANG-URI [QUERY-LANG]]]
        Create a new RDF::Redland::Query object for a query string
        *QUERY-STRING* with optional base URI *BASE-URI* IN QUERY language
        *QUERY-LANG* or query language URI *QUERY-LANG-URI* (both can be
        undef). If *QUERY-LANG-URI* is omitted, the current directory is
        used as the base URI. If *QUERY-LANG-NAME* is undef, the default
        query language "rdql" is used. If *BASE-URI* is omitted, no base URI
        is used.

METHODS
    execute MODEL
        Run the query against model *MODEL* returning a
        RDF::Redland::QueryResults object or undef on failure.
