Detailed Description

In constrast to the QIfServiceObject which is created for you by the QIfServiceManager for every backend plugin, the QIfProxyServiceObject can be instantiated by the user and then manually set to the feature class.

There are two ways to construct a QIfProxyServiceObject. The first takes a QIfServiceInterface pointer as input and can be used to load a backend which is derived from QIfServiceInterface and supposed to be loaded as a plugin, but is part of the same library and can be loaded directly instead. e.g. within a autotest.

The second constructor takes a QHash<QString, QIfFeatureInterface*> and can be used to directly connect a feature class to the backend implementing the QIfFeatureInterface.

See also QIfAbstractFeature.

QIfProxyServiceObject::QIfProxyServiceObject(const QHash<QString, QIfFeatureInterface *> &interfaceMap)

Creates a new QIfProxyServiceObject for the given interfaceMap.

This can be used to directly connect a feature class to the backend implementing the QIfFeatureInterface.

QIfProxyServiceObject::QIfProxyServiceObject(QIfServiceInterface *interface)

Creates a new QIfProxyServiceObject for the given interface.

This can be used to load a backend which is derived from QIfServiceInterface and supposed to be loaded as a plugin, but is part of the same library and can be loaded directly instead. e.g. within a autotest
