Classes
class	BasicStore
	BasicStore is an 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	CacheingPropertyObject
	CacheingPropertyObject is a helper class for managing RDF properties of an object URI – that is, triples that share a common subject and possibly a common prefix for the predicate, and that have only one value for each subject-predicate combination. More...

class	Connection
	Connection provides a connection interface to TransactionalStore, allowing it to be used in a convenient manner familiar to programmers working with SQL databases. More...

class	ConstructionFailedException
	ConstructionFailedException is an exception that may be thrown by ObjectMapper classes if a class mapped from an RDF entity type could not be constructed. More...

class	ContainerBuilder
	ContainerBuilder is a utility class which assists with storage of arbitrary container objects into variant objects and subsequently retrieving them into lists. More...

class	Node
	Node represents a single RDF node, with conversions to and from variant types. More...

class	NoUriException
	NoUriException is an exception thrown by ObjectMapper classes when asked to store a class that is expected to have been assigned a URI already, if its URI property is absent. More...

class	ObjectBuilder
	ObjectBuilder is a singleton object factory capable of constructing new objects of classes that are subclassed from QObject. More...

class	ObjectLoader
	ObjectLoader constructs objects corresponding to nodes in the RDF store and sets properties on those objects corresponding to the node's RDF properties. More...

class	ObjectMapper
	ObjectMapper manages a set of objects, maintaining a consistent record of their state in a TransactionalStore by mapping changes in both directions between objects and store. More...

class	ObjectMapperForwarder
	ObjectMapperForwarder notifies ObjectMapper when a QObject is modified or destroyed. More...

class	ObjectStorer
	ObjectStorer is a storage handler capable of turning objects derived from QObject into RDF triples in a Store, such that under the right conditions the original objects can be recreated from the store by ObjectLoader. More...

class	PropertyObject
	PropertyObject is a helper class for managing RDF properties of an object URI – that is, triples that share a common subject and possibly a common prefix for the predicate, and that have only one value for each subject-predicate combination. More...

class	RDFDuplicateImportException
	RDFDuplicateImportException is an exception that results 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	RDFException
	RDFException is an exception that results from incorrect usage of the RDF store interface or unsuitable data provided to a function. More...

class	RDFIncompleteURI
	RDFIncompleteURI is thrown when an attempt is made to construct a Uri from an incomplete URI string, such as a relative URI or a string with no scheme. More...

class	RDFInternalError
	RDFInternalError is an exception that results from an internal error in the RDF store. More...

class	RDFTransactionError
	RDFTransactionError is an exception that results from incorrect use of a Transaction, for example using a Transaction object after it has been committed. More...

class	RDFUnsupportedError
	RDFUnsupportedError is an exception that results from an attempt to use a feature that is not supported or not configured in the current build. More...

class	Store
	Store is an abstract interface for Dataquay RDF data stores. More...

class	Transaction
	Transaction is an abstract interface for classes that read and write an RDF Store within the context of an atomic operation such as an editing command. More...

class	TransactionalStore
	TransactionalStore is an 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
	Triple represents an RDF statement made up of three Node objects. More...

class	Triples
	A list of RDF triples. More...

class	TypeMapping
	TypeMapping describes a set of relationships between RDF entity and property URIs, and C++ class and QObject property names. More...

class	UnknownTypeException
	UnknownTypeException is an exception thrown by ObjectMapper classes when asked to load an object from an RDF entity whose type cannot be mapped to a C++ class type using the current TypeMapping. More...

class	Uri
	Uri represents a single URI. More...

◆ ResultSet

typedef QList<Dictionary> Dataquay::ResultSet

A list of Dictionary types, used to contain a sequence of query results.

Definition at line 52 of file Store.h.

◆ Change

typedef QPair<ChangeType, Triple> Dataquay::Change

An add or remove operation specified by add/remove token and triple.

Definition at line 60 of file Store.h.

◆ ChangeSet

Enumeration Type Documentation

◆ ChangeType

enum Dataquay::ChangeType

Enumerator
AddTriple
RemoveTriple

Definition at line 54 of file Store.h.

◆ BlankNodePolicy

enum Dataquay::BlankNodePolicy

Enumerator

PermitBlankObjectNodes

Use blank nodes for objects with no existing URIs that are not known to be referred to elsewhere.

This is the default.

NoBlankObjectNodes

Ensure that every object explicitly stored has a URI.

Blank nodes may still appear as list nodes when storing containers.

NeverUseBlankNodes

Never write a blank node: allocate a URI even for list nodes.

Definition at line 40 of file ObjectMapperDefs.h.
