Detailed Description

Interface a kDB::Repository::TripleStore that contains a collection of datasets

Member Function Documentation

allDatasets()

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

static

Returns

an interface to the collection that list all datasets.

createDataset()

cres_qresult< Dataset > Collection::createDataset	(	const knowCore::Uri &	_frameTypeUri,
		const knowGIS::GeometryObject &	_geometry,
		const knowCore::ValueHash &	_properties,
		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()

cres_qresult< Dataset > Collection::dataset

(

const knowCore::Uri &

_datasetUri

)

const

Returns

the dataset with the Uri _datasetUri

datasets()

cres_qresult< QList< Dataset > > Collection::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
