Dataquay Namespace Reference

Classes
class	BasicStore
	In-memory RDF data store implementing the Store interface, providing add, remove, matching and query operations for RDF triples and SPARQL, as well as export and import. More...
class	Connection
	Provides a connection interface to a transactional store, in a manner intended to be familiar to users of SQL database connection interfaces. More...
class	Node
	A single RDF node, with conversions to and from variant types. More...
class	PropertyObject
	Helper class for managing properties of an object URI -- that is, triples that share a common subject and possibly a common prefix for the predicate, and that are unique (having a one-to-one relationship between (subject,predicate) and object). More...
class	CacheingPropertyObject
	Helper class for managing properties of an object URI -- that is, triples that share a common subject and possibly a common prefix for the predicate -- with a demand-populated cache. More...
class	RDFException
	Exception resulting from an error specific to the RDF datastore. More...
class	RDFDuplicateImportException
	Exception resulting from an import into a store from an RDF document in ImportFailOnDuplicates mode, where the document contains a triple that already exists in the store. More...
class	Store
	Abstract interface for Dataquay RDF data stores. More...
class	Transaction
	Interface for reading and writing an RDF Store within the context of an atomic operation such as an editing command. More...
class	TransactionalStore
	RDF data store implementing the Store interface, providing transaction support as a wrapper around a non-transactional store such as a BasicStore. More...
class	Triple
	A triple made up of three Node objects. More...
Typedefs

typedef std::pair< ChangeType, Triple >	Change
	An add or remove operation specified by add/remove token and triple.
typedef QList< Change >	ChangeSet
	A sequence of add/remove operations such as may be enacted by a transaction.
