com.hp.hpl.jena.rdf.model.impl.SelectorImpl
| SelectorImpl | | final public class SelectorImpl extends SimpleSelector (Code) | | A general selector class for use when querying models.
OBSOLETE: use SimpleSelector. This implementation is a stub that provides
only constructors.
An instance of this class is passed with query calls to models. The model
will use the test method of this class to decide whether
a statement should be included in the selection.
Instances of this class can be provided with subject, predicate and object
constraints. If a subject, a predicate or an object are provided,
the model implementation may restrict the statements that it tests
to statements whose subject, predicate and object match those provided in
the constructor. This can provide for considerably more efficient
searching. However, the model implementation is not required to do this.
If no subject, predicate or object are provided in
the constructor, then all statements in the model must be tested.
This class is designed to be subclassed by the application, defining
defining further selection criteria of its own by providing its own
selects method.
The test method first verifies that a statement satisfies
any subject, predicate or object constraints and the calls the
selects method to test for any application supplied constraint. The
default selects method simply returns true.

| Method Summary | |
| public boolean | isSimple()
Answer true to the question "is this a simple selector". |
| SelectorImpl | | public SelectorImpl()(Code) | | Create a selector. Since no subject, predicate or object constraints are
specified a model will test all statements.
|
| SelectorImpl | | public SelectorImpl(Resource subject, Property predicate, RDFNode object)(Code) | | Create a selector. A model may restrict statements that are tested using
the selects method to those whose subject matches the
subject parameter, whose predicate matches the predicate parameter and whose
object matches the object paramater. Any null parameter is considered to
match anything.
Parameters:
subject - if not null, the subject of selected statementsmust equal this argument.
Parameters:
predicate - if not null, the predicate of selected statementsmust equal this argument.
Parameters:
object - if not null, the object of selected statementsmust equal this argument. |
| SelectorImpl | | public SelectorImpl(Resource subject, Property predicate, boolean object)(Code) | | Create a selector. A model may restrict statements that are tested using
the selects method to those whose subject matches the
subject parameter, whose predicate matches the predicate parameter and whose
object matches the object paramater. Any null parameter is considered to
match anything.
Parameters:
subject - if not null, the subject of selected statementsmust equal this argument.
Parameters:
predicate - if not null, the predicate of selected statementsmust equal this argument.
Parameters:
object - if not null, the object of selected statementsmust equal this argument. |
| SelectorImpl | | public SelectorImpl(Resource subject, Property predicate, long object)(Code) | | Create a selector. A model may restrict statements that are tested using
the selects method to those whose subject matches the
subject parameter, whose predicate matches the predicate parameter and whose
object matches the object paramater. Any null parameter is considered to
match anything.
Parameters:
subject - if not null, the subject of selected statementsmust equal this argument.
Parameters:
predicate - if not null, the predicate of selected statementsmust equal this argument.
Parameters:
object - the object of selected statementsmust equal this argument. |
| SelectorImpl | | public SelectorImpl(Resource subject, Property predicate, char object)(Code) | | Create a selector. A model may restrict statements that are tested using
the selects method to those whose subject matches the
subject parameter, whose predicate matches the predicate parameter and whose
object matches the object paramater. Any null parameter is considered to
match anything.
Parameters:
subject - if not null, the subject of selected statementsmust equal this argument.
Parameters:
predicate - if not null, the predicate of selected statementsmust equal this argument.
Parameters:
object - the object of selected statementsmust equal this argument. |
| SelectorImpl | | public SelectorImpl(Resource subject, Property predicate, float object)(Code) | | Create a selector. A model may restrict statements that are tested using
the selects method to those whose subject matches the
subject parameter, whose predicate matches the predicate parameter and whose
object matches the object paramater. Any null parameter is considered to
match anything.
Parameters:
subject - if not null, the subject of selected statementsmust equal this argument.
Parameters:
predicate - if not null, the predicate of selected statementsmust equal this argument.
Parameters:
object - the object of selected statementsmust equal this argument. |
| SelectorImpl | | public SelectorImpl(Resource subject, Property predicate, double object)(Code) | | Create a selector. A model may restrict statements that are tested using
the selects method to those whose subject matches the
subject parameter, whose predicate matches the predicate parameter and whose
object matches the object paramater. Any null parameter is considered to
match anything.
Parameters:
subject - if not null, the subject of selected statementsmust equal this argument.
Parameters:
predicate - if not null, the predicate of selected statementsmust equal this argument.
Parameters:
object - the object of selected statementsmust equal this argument. |
| SelectorImpl | | public SelectorImpl(Resource subject, Property predicate, String object)(Code) | | Create a selector. A model may restrict statements that are tested using
the selects method to those whose subject matches the
subject parameter, whose predicate matches the predicate parameter and whose
object matches the object paramater. Any null parameter is considered to
match anything.
Parameters:
subject - if not null, the subject of selected statementsmust equal this argument.
Parameters:
predicate - if not null, the predicate of selected statementsmust equal this argument.
Parameters:
object - the object of selected statementsmust equal this argument - a null string matches the empty string |
| SelectorImpl | | public SelectorImpl(Resource subject, Property predicate, String object, String language)(Code) | | Create a selector. A model may restrict statements that are tested using
the selects method to those whose subject matches the
subject parameter, whose predicate matches the predicate parameter and whose
object matches the object paramater. Any null parameter is considered to
match anything.
Parameters:
subject - if not null, the subject of selected statementsmust equal this argument.
Parameters:
predicate - if not null, the predicate of selected statementsmust equal this argument.
Parameters:
object - the object of selected statementsmust equal this argument - the null string matches the empty string
Parameters:
language - the language of the object constraint |
| SelectorImpl | | public SelectorImpl(Resource subject, Property predicate, Object object)(Code) | | Create a selector. A model may restrict statements that are tested using
the selects method to those whose subject matches the
subject parameter, whose predicate matches the predicate parameter and whose
object matches the object paramater. Any null parameter is considered to
match anything.
Parameters:
subject - if not null, the subject of selected statementsmust equal this argument.
Parameters:
predicate - if not null, the predicate of selected statementsmust equal this argument.
Parameters:
object - if not null, the object of selected statementsmust equal this argument. |

SimpleSelector subclasses, false, would apply.
