LiteralValue is based on QVariant to support a subset of the XML Schema types that are compatible with QT types.
The following types are supported natively including automatic type conversion. Other types are represented as strings.

LiteralValue& Soprano::LiteralValue::operator= | ( | int | i | ) |
Assigns i to this literal value. The type will be set to int (http://www.w3.org/2001/XMLSchema#int) unless it is already set to a compatible type.
Thus, a type http://www.w3.org/2001/XMLSchema#integer or http://www.w3.org/2001/XMLSchema#decimal will not be changed.
Be aware that Soprano does not check the ranges of the integer value yet.
LiteralValue& Soprano::LiteralValue::operator= | ( | qlonglong | i | ) |
Assigns i to this literal value. The type will be set to long (http://www.w3.org/2001/XMLSchema#long).

Assigns i to this literal value. The type will be set to uint (http://www.w3.org/2001/XMLSchema#unsignedInt) unless it is already set to a compatible type.
Thus, a type http://www.w3.org/2001/XMLSchema#unsignedShort will not be changed.
Be aware that Soprano does not check the ranges of the unsigned value yet.
LiteralValue& Soprano::LiteralValue::operator= | ( | qulonglong | i | ) |
Assigns i to this literal value. The type will be set to unsigned long (http://www.w3.org/2001/XMLSchema#unsignedLong).

static LiteralValue Soprano::LiteralValue::fromString | ( | const QString & | value, | |
QVariant::Type | type | |||

Create a LiteralValue object by parsing string value based on type. If type is unknown a simple string LiteralValue object is returned containing the plain string value.

const QUrl & | dataTypeUri | |||
) | [static] |
Create a LiteralValue object by parsing string value based on dataTypeUri.
value | The value of the literal. Might be converted based on dataTypeUri. | |
dataTypeUri | The data type URI. Soprano can automatically convert all XML schema types. All other (unknown) types will be stored as a string value with the plain dataTypeUri as type. Thus, unknown literal types can still be used without automatic type conversion. (Be aware though, that changing the value of a LiteralValue instance will reset the type, ie. custom data type URIs will be lost.) |
static QVariant::Type Soprano::LiteralValue::typeFromDataTypeUri | ( | const QUrl & | dataTypeUri | ) | [static] |
Convert an XML Schema URI into a QVariant::Type.
static QUrl Soprano::LiteralValue::dataTypeUriFromType | ( | QVariant::Type | type | ) | [static] |

or an empty QUrl if the type os unknown, i.e. can not be mapped to an XML Schema type.
