Method Detail

getPreconditionQuery

String getPreconditionQuery()

Returns:

String - a SPARQL query

setPreconditionQuery

void setPreconditionQuery(String preconditionQuery)

Parameters:

preconditionQuery - - a SPARQL query

getPreconditionQueryType

RDFService.SPARQLQueryType getPreconditionQueryType()

Returns:

RDFService.SPARQLQueryType - the precondition query type

setPreconditionQueryType

void setPreconditionQueryType(RDFService.SPARQLQueryType queryType)

Parameters:

queryType - - the precondition query type

getModelChanges

List<ModelChange> getModelChanges()

addAddition

void addAddition(InputStream model,
                 RDFService.ModelSerializationFormat serializationFormat,
                 String graphURI)

Adds one model change representing an addition to the list of model changes

Parameters:

model - - a serialized RDF model (collection of triples)

serializationFormat - - format of the serialized RDF model

graphURI - - URI of the graph to which the RDF model should be added

addRemoval

void addRemoval(InputStream model,
                RDFService.ModelSerializationFormat serializationFormat,
                String graphURI)

Adds one model change representing a deletion to the list of model changes

Parameters:

model - - a serialized RDF model (collection of triples)

serializationFormat - - format of the serialized RDF model

graphURI - - URI of the graph from which the RDF model should be removed

manufactureModelChange

ModelChange manufactureModelChange()

Creates an instance of the ModelChange class

Returns:

ModelChange - an empty instance of the ModelChange class

manufactureModelChange

ModelChange manufactureModelChange(InputStream serializedModel,
                                   RDFService.ModelSerializationFormat serializationFormat,
                                   ModelChange.Operation operation,
                                   String graphURI)

Creates an instance of the ModelChange class

Parameters:

serializedModel - - a serialized RDF model (collection of triples)

serializationFormat - - format of the serialized RDF model

operation - - the type of operation to be performed with the serialized RDF model

graphURI - - URI of the graph on which to apply the model change operation

Returns:

ModelChange - a ModelChange instance initialized with the input model, model format, operation and graphURI

addPreChangeEvent

void addPreChangeEvent(Object event)

Adds an event that will be be passed to any change listeners in advance of the change set additions and retractions being performed. The event will only be fired if the precondition (if any) is met.

Parameters:

event - - event to notify listeners of in advance of making changes to the triple store.

addPostChangeEvent

void addPostChangeEvent(Object event)

Adds an event that will be be passed to any change listeners after all of the change set additions and retractions are performed.

Parameters:

event - - the event to notify listeners of after the changes are performed.

getPreChangeEvents

List<Object> getPreChangeEvents()

Returns a list of events to pass to any change listeners in advance of the change set additions and retractions being performed.

getPostChangeEvents

List<Object> getPostChangeEvents()

Returns a list of events to pass to any change listeners after the change set additions and retractions are performed.
