All known Subclasses: com.hp.hpl.jena.rdf.model.impl.ModelMakerImpl,
| ModelMaker | | public interface ModelMaker extends ModelSource(Code) | | A ModelMaker contains a collection of named models, methods for creating
new models [both named and anonymous] and opening previously-named
models, removing models, and accessing a single "default" Model for this
Maker.
Additional constraints are placed on a ModelMaker as compared to its
ancestor ModelSource. ModelMakers do not arbitrarily forget
their contents - once they contain a named model, that model stays inside
the ModelMaker until that ModelMaker goes away, and maybe for longer
(eg if the ModelMaker fronted a database or directory). And new models
can be added to a ModelMaker.

| Method Summary | |
| public void | close()
Close the factory - no more requests need be honoured, and any clean-up
can be done. | | public Model | createModel(String name, boolean strict)
Create a new Model associated with the given name. | | public Model | createModel(String name)
Create a Model that does not already exist - equivalent to
createModel( name, false ). | | public GraphMaker | getGraphMaker()
Answer a GraphMaker that makes graphs the same way this ModelMaker
makes models. | | public boolean | hasModel(String name)
| | public ExtendedIterator | listModels()
Answer an [extended] iterator where each element is the name of a model in
the maker, and the complete sequence exhausts the set of names. | | public Model | openModel(String name, boolean strict)
Find an existing Model that this factory knows about under the given
name. | | public void | removeModel(String name)
Remove the association between the name and the Model. |
| close | | public void close()(Code) | | Close the factory - no more requests need be honoured, and any clean-up
can be done.
|
| createModel | | public Model createModel(String name, boolean strict)(Code) | | Create a new Model associated with the given name. If there is no such
association, create one and return it. If one exists but strict
is false, return the associated Model. Otherwise throw an AlreadyExistsException.
Parameters:
name - the name to give to the new Model
Parameters:
strict - true to cause existing bindings to throw an exception
exception:
AlreadyExistsException - if that name is already bound. |
| createModel | | public Model createModel(String name)(Code) | | Create a Model that does not already exist - equivalent to
createModel( name, false ).
|
| getGraphMaker | | public GraphMaker getGraphMaker()(Code) | | Answer a GraphMaker that makes graphs the same way this ModelMaker
makes models. In general this will be an underlying GraphMaker.
|
| hasModel | | public boolean hasModel(String name)(Code) | | return true iff the factory has a Model with the given name
Parameters:
name - the name of the Model to look for true iff there's a Model with that name |
| listModels | | public ExtendedIterator listModels()(Code) | | Answer an [extended] iterator where each element is the name of a model in
the maker, and the complete sequence exhausts the set of names. No particular
order is expected from the list.
an extended iterator over the names of models known to this Maker. |
| openModel | | public Model openModel(String name, boolean strict)(Code) | | Find an existing Model that this factory knows about under the given
name. If such a Model exists, return it. Otherwise, if strict
is false, create a new Model, associate it with the name, and return it.
Otherwise throw a DoesNotExistException.
When called with strict=false, is equivalent to the
ancestor openModel(String) method.
Parameters:
name - the name of the Model to find and return
Parameters:
strict - false to create a new one if one doesn't already exist
exception:
DoesNotExistException - if there's no such named Model |
| removeModel | | public void removeModel(String name)(Code) | | Remove the association between the name and the Model. create
will now be able to create a Model with that name, and open will no
longer be able to find it. Throws an exception if there's no such Model.
The Model itself is not touched.
Parameters:
name - the name to disassociate
exception:
DoesNotExistException - if the name is unbound |
