Utility methods for working with schema.org data in JSON-LD format.

Function Documentation

◆ canConvert()

template<typename T >
bool KItinerary::JsonLd::canConvert ( const QVariant & value)
inline

Checks if the given value can be up-cast to T.

Definition at line 31 of file datatypes.h.

◆ convert()

template<typename T >
T KItinerary::JsonLd::convert ( const QVariant & value)
inline

Up-cast value to T.

Note
This does not perform any safety checks!

canConvert

Definition at line 47 of file datatypes.h.

◆ isA()

template<typename T >
bool KItinerary::JsonLd::isA ( const QVariant & value)
inline

Returns true if value is of type T.

Definition at line 24 of file datatypes.h.

◆ isSchemaOrgNamespace()

bool KItinerary::JsonLd::isSchemaOrgNamespace ( QStringView uri)

Checks whether uri is in the http://schema.org namespace.

That is more complex than just startsWith since schema.org started to use "https" in their URIs...

Definition at line 31 of file json/jsonld.cpp.

◆ normalizeTypeName()

QString KItinerary::JsonLd::normalizeTypeName ( QString && typeName)

Definition at line 20 of file json/jsonld.cpp.

◆ renameProperty()

void KItinerary::JsonLd::renameProperty ( QJsonObject & obj,
const char * oldName,
const char * newName )

Rename a property, if present and the new name isn't in use already.

Definition at line 17 of file jsonldfilterengine.cpp.

◆ typeName()

QString KItinerary::JsonLd::typeName ( const QJsonObject & obj)

Normalized type name from object.

Definition at line 15 of file json/jsonld.cpp.

◆ valueIsNull()

bool KItinerary::JsonLd::valueIsNull ( const QVariant & v)

Checks whether v holds a null-like value.

This is similar to QVariant::isNull in Qt5, but differs from the "shallow" QVariant::isNull in Qt6 which doesn't check the content at all.

Definition at line 370 of file jsonlddocument.cpp.
