Method Detail

changeOperationPerformed

public void changeOperationPerformed(ChangeOperation operation,
                                     boolean undone)

Checks if the currently selected resource has been deleted as a result of a ModelOperation. If yes, then the ontology is selected.

Specified by:

changeOperationPerformed in interface IChangeEngineListener

Parameters:

operation -

undone -

ensureBaseModelExists

public com.hp.hpl.jena.rdf.model.Model ensureBaseModelExists(java.net.URI baseURI)

Description copied from interface: ISession

Manually ensures that a Model has been instantiated and registered for a given base URI/Graph combination. This call is typically not needed - only by low-level applications that manually load graphs.

Specified by:

ensureBaseModelExists in interface ISession

Parameters:

baseURI - the base URI to register

Returns:

the Model (never null)

getBaseModel

public com.hp.hpl.jena.rdf.model.Model getBaseModel(com.hp.hpl.jena.graph.Graph graph)

Description copied from interface: ISession

Gets the base model used for a given graph in this session.

Specified by:

getBaseModel in interface ISession

Returns:

getBaseModel

public com.hp.hpl.jena.rdf.model.Model getBaseModel(java.net.URI baseURI)

Description copied from interface: ISession

Gets the current base Model for a given base URI, if one is loaded. This method only returns not null if registerModel has been called for this URI before, and no invokation of unregister has happened in the meantime.

Specified by:

getBaseModel in interface ISession

Parameters:

baseURI - the URI to get the Model for

Returns:

the Model if it has been loaded or null if not

getBaseModel

public com.hp.hpl.jena.rdf.model.Model getBaseModel(com.hp.hpl.jena.ontology.OntModel ontModel)

getChangeEngine

public IChangeEngine getChangeEngine()

Description copied from interface: ISession

Gets the session's change engine. The change engine is responsible for write operations on the current models.

Specified by:

getChangeEngine in interface ISession

Returns:

the IChangeEngine (or null)

getInferenceModel

public com.hp.hpl.jena.rdf.model.Model getInferenceModel(com.hp.hpl.jena.ontology.OntModel ontModel)

getOntModel

public com.hp.hpl.jena.ontology.OntModel getOntModel(java.net.URI baseURI)

Description copied from interface: ISession

Gets the OntModel that has been associated with a given base URI in this session. In a multi-user setting, this will return the user's OntModel, i.e. there may be different results depending on the session.

Specified by:

getOntModel in interface ISession

Parameters:

baseURI - the base URI

Returns:

the OntModel or null if none exists (yet)

getSystemModel

public com.hp.hpl.jena.rdf.model.Model getSystemModel(com.hp.hpl.jena.ontology.OntModel ontModel)

graphChangePerformed

public void graphChangePerformed()

Description copied from interface: IChangeEngineListener

Notifies the receiver that a global change to the current model has been performed. This is typically called when new sub-Graphs have been added or removed, allowing the receiver to do a complete refresh.

Specified by:

graphChangePerformed in interface IChangeEngineListener

graphDirty

public void graphDirty(com.hp.hpl.jena.graph.Graph graph)

Description copied from interface: IChangeEngineListener

Called when a Graph has been set to dirty.

Specified by:

graphDirty in interface IChangeEngineListener

Parameters:

graph - the Graph that has changed

initChangeEngine

public void initChangeEngine(TBCChangeEngine changeEngine)

isDeletable

public boolean isDeletable(com.hp.hpl.jena.rdf.model.Statement statement)

Description copied from interface: ISession

Checks whether a given Statement can be deleted, i.e. whether the triple is stored in a read-only graph.

Specified by:

isDeletable in interface ISession

Parameters:

statement - the statement to check

Returns:

true if s can be deleted

isEditable

public boolean isEditable(java.net.URI baseURI)

Specified by:

isEditable in interface ISession

isVisible

public boolean isVisible(com.hp.hpl.jena.rdf.model.Resource resource)

Description copied from interface: ISession

Checks if a given Resource is visible for this session. While it is completely up to the UI to decide what to do with invisible resources, it is recommended that invisible resources are not shown in dialogs, forms and trees.

Specified by:

isVisible in interface ISession

Parameters:

resource - the resource to test

Returns:

true if resource is visible

listModels

public java.util.Iterator<com.hp.hpl.jena.rdf.model.Model> listModels()

public void registerBaseModel(java.net.URI baseURI,
                              com.hp.hpl.jena.rdf.model.Model baseModel)

replaceBaseURI

public void replaceBaseURI(java.net.URI oldURI,
                           java.net.URI newURI)
