Detailed Description

A plugin database that works with installed modules.

Member Function Documentation

getSymbol()

PluginDatabase::func_t kdb::tools::ModulesPluginDatabase::getSymbol ( PluginSpec const &  whichplugin, std::string const &  which  ) const

virtual

get exported plugin symbol

Parameters

whichplugin	from which plugin?
which	which symbol would you like to look up?

Returns

the function pointer to the exported symbol or NULL if the symbol was not found

Implements kdb::tools::PluginDatabase.

Reimplemented in kdb::tools::MockPluginDatabase.

listAllPlugins()

std::vector< std::string > kdb::tools::ModulesPluginDatabase::listAllPlugins ( ) const

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

Implements kdb::tools::PluginDatabase.

Reimplemented in kdb::tools::MockPluginDatabase.

lookupAllProvides()

std::vector< PluginSpec > kdb::tools::ModulesPluginDatabase::lookupAllProvides ( std::string const &  provides ) const

virtual

looks up all plugins which are a suitable provider

Note

in case a plugin name is provided, the plugin with the name will also be part of the result. But if there are other plugins providing the requirement, then they will also be part of the result. The ordering of the resulting vector has no special meaning.

Parameters

provides

is the provider to find

Returns

a vector of plugins offering the requirement or are named after it

Implements kdb::tools::PluginDatabase.

lookupAllProvidesWithStatus()

std::map< int, PluginSpec > kdb::tools::ModulesPluginDatabase::lookupAllProvidesWithStatus ( std::string const &  provides ) const

virtual

looks up all plugins which are a suitable provider

Note

in case a plugin name is provided, the plugin with the name will also be part of the result. But if there are other plugins providing the requirement, then they will also be part of the result.

Parameters

provides

is the provider to find

Returns

a map of plugins with their status offering the requirement or are named after it

Implements kdb::tools::PluginDatabase.

lookupInfo()

std::string kdb::tools::ModulesPluginDatabase::lookupInfo ( PluginSpec const &  whichplugin, std::string const &  which  ) const

virtual

lookup contract clauses or dynamic information

Parameters

whichplugin	about which plugin?
which	about which clause in the contract?

Returns

the clause of the contract

Implements kdb::tools::PluginDatabase.

Reimplemented in kdb::tools::MockPluginDatabase.

lookupMetadata()

PluginSpec kdb::tools::ModulesPluginDatabase::lookupMetadata ( std::string const &  which ) const

virtual

lookup which plugin handles metadata

Parameters

which

the metadata of interest

Returns

the best suited plugin specification which provides it

Implements kdb::tools::PluginDatabase.

lookupProvides()

PluginSpec kdb::tools::ModulesPluginDatabase::lookupProvides ( std::string const &  provides ) const

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

provides

is the provider to find

Exceptions

NoPlugin

if no plugin that provides the functionality could be found

Returns

the plugin itself or the best suited plugin specification which provides it

Implements kdb::tools::PluginDatabase.
