Detailed Description

Plugin factory implementation class.

The Plugin factory is used to load shared libraries which export plugin objects for a given interface (class). The factory will only load shared libraries which export features for the interface given in the constructor, others will be silently ignored. Using the feature as an identifier you can create instances of dynamically loaded objects. Please use the PluginFactory template class which avoids typecasts.
