Detailed Description

Integration component for combining multiple command factories.

Serves as a bridge between different command subsystems (CLI, Server). When creating a command, it tries each registered factory in order until one successfully creates the command. This design allows clean separation of concerns while providing a unified command interface to the application.

Constructor & Destructor Documentation

CompositeCommandFactory()

svcs::integration::CompositeCommandFactory::CompositeCommandFactory	(	std::shared_ptr< ISubject >	event_bus,
		std::shared_ptr< RepositoryManager >	repo_manager )

Constructs a CompositeCommandFactory with necessary dependencies.

Parameters

event_bus	Shared pointer to the event bus for command notifications.
repo_manager	Shared pointer to the repository manager for repository operations.

Member Function Documentation

commandExists()

bool svcs::integration::CompositeCommandFactory::commandExists

(

const std::string &

name

)

const

Checks if a command with the given name exists.

Parameters

name	The name of the command to check.

Returns

True if any registered factory can create the command, false otherwise.

Tries to create the command to determine existence.

createCommand()

std::unique_ptr< ICommand > svcs::integration::CompositeCommandFactory::createCommand

(

const std::string &

name

)

const

Creates a command by name using registered factories.

Parameters

name	The name of the command to create.

Returns

Unique pointer to the created command, or nullptr if no factory can create it.

Tries each registered factory in order until one successfully creates the command. Returns the first non-null command found.

getAllCommandNames()

std::vector< std::string > svcs::integration::CompositeCommandFactory::getAllCommandNames

(

)

const

Gets names of all available commands from all factories.

Returns

Vector of all command names that can be created by any registered factory.

Collects command names from all registered factories, removing duplicates. Commands are returned in registration order (factory order), not alphabetical order.

getCommandDescription()

std::string svcs::integration::CompositeCommandFactory::getCommandDescription

(

const std::string &

name

)

const

Gets the description for a command.

Parameters

name	The name of the command.

Returns

Command description, or error message if command not found.

Creates a temporary command instance to retrieve its description. If command cannot be created, returns an appropriate error message.

getFactoryCount()

size_t svcs::integration::CompositeCommandFactory::getFactoryCount

(

)

const

Gets the number of registered factories.

Returns

Number of factory functions currently registered.

registerFactory()

void svcs::integration::CompositeCommandFactory::registerFactory

(

std::function< std::unique_ptr< ICommand >(const std::string &)>

factory

)

Registers a factory function for command creation.

Parameters

factory

Factory function that takes a command name and returns a command pointer.

Factories are called in the order they are registered until one returns a non-null command. This allows prioritizing certain command types over others.

showCommandHelp()

void svcs::integration::CompositeCommandFactory::showCommandHelp

(

const std::string &

name

)

const

Shows detailed help for a command.

Parameters

name	The name of the command.

Creates a temporary command instance and calls its showHelp method. If command cannot be created, shows an error message.
