Defines the basic interface for a plugin manager that also keeps track of versions of plugins
Gather some info about a plugin such as its name, author, description...
Handle plugin versioning by making sure that when several versions are present for a same plugin, only the latest version is manipulated via the standard methods (eg for activation and deactivation)
More precisely, for operations that must be applied on a single named plugin at a time (getPluginByName, activatePluginByName, deactivatePluginByName etc) the targetted plugin will always be the one with the latest version.
Note
The older versions of a given plugin are still reachable via the getPluginsOfCategoryFromAttic method.
DEPRECATED(>1.8): Please consider using getPluginsOfCategory instead.
Return the list of all plugins belonging to a category.
Access the older version of plugins for which only the latest version is available through standard methods.
Load the candidate plugins that have been identified through a previous call to locatePlugins.
In addition to the baseclass functionality, this subclass also needs to find the latest version of each plugin.
