int kdb::tools::PluginDatabase::calculateStatus ( std::string  statusString)
static
Parameters
statusStringthe string encoding the status
Returns
The representing number for a given status.
virtual std::vector<std::string> kdb::tools::PluginDatabase::listAllPlugins ( ) const
pure virtual

list all plugins

If Elektra is compiled with plugins, it will search for shared libraries. In any case, if no shared libraries were found it will fallback to an internal list (plugins that were compiled together with Elektra).

Returns
a list of all available plugins

Implemented in kdb::tools::MockPluginDatabase, and kdb::tools::ModulesPluginDatabase.

virtual std::string kdb::tools::PluginDatabase::lookupInfo ( PluginSpec const &  whichplugin,
std::string const &  which 
) const
pure virtual

lookup contract clauses or dynamic information

Parameters
whichpluginabout which plugin?
whichabout which clause in the contract?
Returns
the clause of the contract

Implemented in kdb::tools::MockPluginDatabase, and kdb::tools::ModulesPluginDatabase.

virtual PluginSpec kdb::tools::PluginDatabase::lookupMetadata ( std::string const &  which) const
pure virtual

lookup which plugin handles meta data

Parameters
whichthe meta data of interest
Returns
the best suited plugin specification which provides it

Implemented in kdb::tools::ModulesPluginDatabase.

virtual PluginSpec kdb::tools::PluginDatabase::lookupProvides ( std::string const &  provides) const
pure virtual

lookup which plugin is a provider for that plugin

Note
will return a PluginSpec with getName() == provides if the string provides actually is a plugin name.
Parameters
providesis the provider to find
Exceptions
NoPluginif no plugin that provides the functionality could be found
Returns
the plugin itself or the best suited plugin specification which provides it

Implemented in kdb::tools::ModulesPluginDatabase.
