Detailed Description

This class handles the storage of a value of a RDF Literal in the database.

Values are stored using multiple types, each different types is stored in a different field. There should be only field in use at a given time.

Member Function Documentation

knowCore::ReturnVoid RDFValueBinaryMarshal::registerTerm	(	const Connection &	_connection,
		const knowCore::Uri &	_defaultUri,
		const QString &	_typename,
		const QString &	_cast_typename = QString() )

static

This function generate additional create term function, provided that _typename can be casted to an exisiting value

knowCore::ReturnValue< QByteArray > RDFValueBinaryMarshal::toByteArray	(	const knowCore::Value &	_source,
		QString &	_oidName,
		const kDB::Repository::Connection &	_connection ) const

overridevirtual

Convert a knowCore::Value to a postgresql binary representation.

Parameters

_oidName is filled with the postgresql OID name

knowCore::ReturnValue< knowCore::Value > RDFValueBinaryMarshal::toValue	(	const QByteArray &	_source,
		const kDB::Repository::Connection &	_connection ) const

overridevirtual

Convert from a postgresql binary representation to a knowCore::Value value.
