Detailed Description
You can register one or more datapoints with this factory and query them based on the main number and sub number.
This class follows the singleton design pattern. Only one instance of this class can be created and its reference can be fetched from the instance() method.
The KNX datapoint types are identified by a 16-bit main number and a 16-bit sub number.
See also Qt KNX Datapoint Type Classes.
Member Function Documentation
bool QKnxDatapointTypeFactory::containsMainType(int mainType) const
Queries the factory for a the given mainType and if it is registered, returns true; false otherwise.
bool QKnxDatapointTypeFactory::containsSubType(int mainType, int subType) const
Queries the factory for a the given mainType and subType and if the type is registered, returns true; false otherwise.
QKnxDatapointType *QKnxDatapointTypeFactory::createType(int mainType, int subType) const
Returns a new instance of a QKnxDatapointType subclass. The instantiation of the subclass depends on the mainType and subType given as arguments to this function.
Note: The ownership of the created object remains with the programmer.
QKnxDatapointType *QKnxDatapointTypeFactory::createType(QKnxDatapointType::Type type) const
Returns a new instance of a QKnxDatapointType subclass. The instantiation of the subclass depends on the type given as an argument to this function.
Note: The ownership of the created object remains with the programmer.
[static] QKnxDatapointTypeFactory &QKnxDatapointTypeFactory::instance()
Returns a reference to the datapoint type factory.
QList<int> QKnxDatapointTypeFactory::mainTypes() const
Returns a list of registered main datapoint types.
template <typename Class> void QKnxDatapointTypeFactory::registerType(int mainType, int subType, int size)
Registers a datapoint type with the main type mainType, sub type subType, and size size.
QList<int> QKnxDatapointTypeFactory::subTypes(int mainType) const
Returns a list of registered sub datapoint types for the given mainType.
[static] int QKnxDatapointTypeFactory::typeSize(int mainType)
Returns the size in bytes for the given mainType.
