public interface ModelFactory

RDF2Go adapters have toi implement this interface to be able to create Models and ModelSets. Property keys are defined in this interface (Reasoning, Storage).

Field Summary

static java.lang.String	REASONING The Property key to indicate the Reasoning state in the properties.
static java.lang.String	STORAGE The Property key to indicate where to store the model or modelset.

Method Summary

Model	createModel() Create a default in-memory ModelSet with no inferencing.
Model	createModel(java.util.Properties p) Create a Model configured by the given properties.
Model	createModel(Reasoning reasoning) Create a new Model with inferencing.
Model	createModel(URI contextURI) Create a default in-memory ModelSet with no inferencing and the given context URI.
ModelSet	createModelSet() create a default in-memory ModelSet with no inferencing.
ModelSet	createModelSet(java.util.Properties p) Create a ModelSet configured by the given properties.
ModelSet	createModelSet(Reasoning reasoning) Create a default in-memory ModelSet with given inferencing.

Method Detail

createModel

Model createModel()
                  throws ModelRuntimeException

Create a default in-memory ModelSet with no inferencing.

Returns:

a Model implementation.

Throws:

ModelRuntimeException - if the adapter could not create the model

createModel

Model createModel(URI contextURI)
                  throws ModelRuntimeException

Create a default in-memory ModelSet with no inferencing and the given context URI. All statements added to this model will have this context as the context of each statement.

Returns:

a Model implementation bound to the given context URI.

Throws:

ModelRuntimeException - if the adapter could not create the model

createModel

Model createModel(Reasoning reasoning)
                  throws ReasoningNotSupportedException,
                         ModelRuntimeException

Create a new Model with inferencing. Type of reasoning is passed.

Parameters:

reasoning - the type of reasoning that is needed

Returns:

a model with reasoning support

Throws:

ModelRuntimeException - if the adapter could not create the Model

ReasoningNotSupportedException - if the passed kind of reasoning is not supported.

createModel

Model createModel(java.util.Properties p)
                  throws ModelRuntimeException

Create a Model configured by the given properties. You have to look at the adapter documentation to see which properties do what.

Parameters:

properties - configures the to-be-created Model

Returns:

the created Model

Throws:

ModelRuntimeException - if the adapter could not create the Model

ReasoningNotSupportedException - if the passed kind of reasoning is not supported.

ModelRuntimeException

createModelSet

ModelSet createModelSet()
                        throws ModelRuntimeException

create a default in-memory ModelSet with no inferencing.

Returns:

a ModelSet implementation.

Throws:

NotImplementedException - a RuntimeException if this method is not implemented. Should not happen.

ModelRuntimeException

createModelSet

ModelSet createModelSet(Reasoning reasoning)
                        throws ReasoningNotSupportedException,
                               ModelRuntimeException

Create a default in-memory ModelSet with given inferencing. Type of reasoning is passed.

Parameters:

reasoning - the type of reasoning that is needed

Returns:

the created ModelSet

Throws:

ModelRuntimeException

ReasoningNotSupportedException - if the passed kind of reasoning is not supported.

ModelRuntimeException - if the adapter could not create the model

createModelSet

ModelSet createModelSet(java.util.Properties p)
                        throws ModelRuntimeException

Create a ModelSet configured by the given properties. You have to look at the adapter documentation to see which properties do what.

Parameters:

properties - - configures the model creation

Returns:

the created ModelSet

Throws:

ModelRuntimeException - if the adapter could not create the Model

ReasoningNotSupportedException - if the passed kind of reasoning is not supported.
