Detailed Description

This is the abstract factory for plugin engines.

If you want a specific engine in order to load a plugin you can use a command like: te::plugin::AbstractPluginEngine* pEngine = te::plugin::PluginEngineFactory::make("C++");

Note

The caller of the method make will take the ownership of the returned engine.

Member Function Documentation

virtual AbstractPluginEngine * te::common::AbstractFactory< AbstractPluginEngine , std::string , std::less<std::string > >::build ( )

protectedpure virtualinherited

Concrete factories (derived from this one) must implement this method in order to create objects.

Returns

It returns an object created by the concrete factory.

Implemented in te::plugin::CppPluginEngineFactory.

static const factory_type* te::common::AbstractFactory< AbstractPluginEngine , std::string , std::less<std::string > >::find ( const std::string &  factoryKey )

staticinherited

static dictionary_type& te::common::AbstractFactory< AbstractPluginEngine , std::string , std::less<std::string > >::getDictionary ( )

staticinherited

It returns a reference to the internal dictionary of concrete factories.

The dictionary is a singleton.

Returns

A reference to the internal dictionary.

const std::string & te::common::AbstractFactory< AbstractPluginEngine , std::string , std::less<std::string > >::getKey ( ) const

inherited

It returns the factory key associated to the concreate factory.

Returns

The factory key associated to the concreate factory.

static AbstractPluginEngine * te::common::AbstractFactory< AbstractPluginEngine , std::string , std::less<std::string > >::make ( const std::string &  factoryKey )

staticinherited

It creates an object with the appropriated factory.

Parameters

factoryKey

A key that identifies the factory used to build the object.

Returns

It returns a new object created by the given factory.

Exceptions

Exception

If the concrete factory is not specified or the object can not be built for any reason this methiod may throws an exception.

Note

The caller of this method will take the ownership of the returned object.
