Member Function Documentation

all()

QList< Dataset > Datasets::all

(

)

const

Returns

all the dataset contained in this document.

allCollectionsUris()

knowCore::ReturnValue< QList< knowCore::Uri > > Datasets::allCollectionsUris ( const kDB::Repository::Connection & _connection )

static

Returns

a list of the uris of all datasets documents.

a list of the uris of all collections.

allDatasets()

Datasets Datasets::allDatasets ( const kDB::Repository::Connection & _connection )

static

Returns

an interface to the view that covers all datasets.

connection()

kDB::Repository::Connection Datasets::connection

(

)

const

Returns

the connection

count()

std::size_t Datasets::count

(

)

const

Returns

the number of datasets in this document.

create()

knowCore::ReturnValue< Dataset > Datasets::create ( const kDB::Repository::Connection & _connection, const knowCore::Uri & _graph )

static

Create a new kDB::Repository::TriplesStore with uri _graph, add it to the union of datasets Uris::kdb_sensing::datasets.

Returns

an invalid Datasets if an error occurs or if the datasets already exists

createDataset()

knowCore::ReturnValue< Dataset > Datasets::createDataset	(	const knowCore::Uri &	_typeUri,
		const knowGIS::GeometryObject &	_geometry,
		const knowCore::Uri &	_datasetUri = knowCore::Uri::createUnique({"dataset"}) )

Create a new Dataset of uri type _typeUri with geometry _geometry and add it to the _rdfGraph.

dataset()

knowCore::ReturnValue< Dataset > Datasets::dataset

(

const knowCore::Uri &

_datasetUri

)

const

Returns

the dataset with the Uri _datasetUri

datasets()

knowCore::ReturnValue< QList< Dataset > > Datasets::datasets	(	const QList< QPair< knowCore::Uri, knowCore::ConstrainedValue > > &	_constraints,
		const OperatorOptions &	_operatorOptions = OperatorOptions() ) const

Parameters

_constraints	a list of pair of list of uris representing the property uri and a constraint.
_operatorOptions	set the precision used by operators

Returns

the list of datasets that satisfies the constraints

get()

knowCore::ReturnValue< Datasets > Datasets::get ( const kDB::Repository::Connection & _connection, const knowCore::Uri & _graph )

static

Return an unique instance of the datasets stored in _graph for a given _connection

Returns

an invalid Datasets if it does not exists

getOrCreate()

knowCore::ReturnValue< Datasets > Datasets::getOrCreate ( const kDB::Repository::Connection & _connection, const knowCore::Uri & _graph )

static

Create or access the datasets specified in _graph

Returns

an invalid Datasets if an error occurs

insert()

knowCore::ReturnVoid Datasets::insert

(

const Dataset &

_dataset

)

Insert an existing _dataset in this set of datasets.

Returns

true if successful or false in case of error or if the _dataset is already in this set of datasets

isReadOnly()

bool Datasets::isReadOnly

(

)

const

Returns

true if it can only be used to access datasets and not insert one.

isValid()

bool Datasets::isValid

(

)

const

Returns

true if it is a valid set of datasets

uri()

knowCore::Uri Datasets::uri

(

)

const

Returns

the uri for the graph
