Detailed Description

This class is resposible for finding an Action for new requests and invoking it.

Definition at line 28 of file dispatcher.h.

Constructor & Destructor Documentation

◆ Dispatcher()

Dispatcher::Dispatcher ( QObject * parent = nullptr )

Constructs a new Dispatcher object with the given parent.

Definition at line 23 of file dispatcher.cpp.

References QObject::parent().

◆ ~Dispatcher()

Dispatcher::~Dispatcher ( )

Destroys the Dispatcher object.

Definition at line 31 of file dispatcher.cpp.

Member Function Documentation

◆ controller()

Controller * Dispatcher::controller ( QStringView name ) const

Returns a Controller given it's name.

Definition at line 266 of file dispatcher.cpp.

Referenced by setupActions().

◆ controllers()

QList< Controller * > Dispatcher::controllers ( ) const

Returns a list of registered controllers.

Definition at line 272 of file dispatcher.cpp.

References QList::append().

Referenced by setupActions().

◆ dispatch()

bool Dispatcher::dispatch ( Context * c )

protected

Delegate the dispatch to the action that matched the url, or return a message about unknown resource.

Definition at line 123 of file dispatcher.cpp.

References Cutelyst::Controller::_DISPATCH(), Cutelyst::Context::action, Cutelyst::Context::appendError(), QString::arg(), Cutelyst::Action::controller(), QString::isEmpty(), Cutelyst::Context::qtTrId(), and Cutelyst::Context::req.

Referenced by expandAction(), setupActions(), and uriForAction().

◆ dispatchers()

QVector< DispatchType * > Dispatcher::dispatchers ( ) const

Returns a list of all dispatchers currently in use, if the dispatcher doesn't successfuly register an Action it's removed from the list.

Definition at line 315 of file dispatcher.cpp.

Referenced by setupActions().

◆ expandAction()

Action * Dispatcher::expandAction	(	const Context *	c,
		Action *	action
	)		const

Expand an action into a full representation of the dispatch. Mostly useful for chained where the returned Action will be of ActionChain type, other actions will just return a single action.

Definition at line 303 of file dispatcher.cpp.

References dispatch().

◆ forward() [1/2]

bool Dispatcher::forward	(	Context *	c,
		Component *	component
	)

protected

Used by Application to forward execution to the following Component.

Definition at line 141 of file dispatcher.cpp.

References Cutelyst::Context::execute().

◆ forward() [2/2]

bool Dispatcher::forward	(	Context *	c,
		QStringView	opname
	)

protected

Used by Application to forward execution to opname that is resolved to an Action.

Definition at line 149 of file dispatcher.cpp.

References Cutelyst::Action::dispatch(), and Cutelyst::Context::request.

◆ getAction()

Action * Dispatcher::getAction	(	QStringView	name,
		QStringView	nameSpace = `{}`
	)		const

Returns an action by name from a given nameSpace.

Definition at line 216 of file dispatcher.cpp.

References getActionByPath(), and QStringView::isEmpty().

◆ getActionByPath()

Action * Dispatcher::getActionByPath ( QStringView path ) const

Returns an action by its full private path.

Definition at line 232 of file dispatcher.cpp.

References QStringView::count(), QStringView::mid(), and QStringView::startsWith().

Referenced by Cutelyst::RoleACL::dispatcherReady(), and getAction().

◆ getActions()

ActionList Dispatcher::getActions	(	QStringView	name,
		QStringView	nameSpace
	)		const

Returns a list of actions that match name on the desired namespace nameSpace.

Definition at line 245 of file dispatcher.cpp.

References QList::append(), QStringView::isEmpty(), QList::rbegin(), and QList::rend().

◆ prepareAction()

void Dispatcher::prepareAction ( Context * c )

protected

Used by Application to find a matching action for the current Context c.

Definition at line 162 of file dispatcher.cpp.

References QList::isEmpty(), QString::isEmpty(), QStringList::join(), and Cutelyst::Context::request.

◆ setupActions()

void Dispatcher::setupActions	(	const QVector< Controller * > &	controllers,
		const QVector< DispatchType * > &	dispatchers,
		bool	printActions
	)

protected

Used by Application to register all Controllers Actions into the list of DispatchType.

Definition at line 36 of file dispatcher.cpp.

References Cutelyst::Controller::actions(), QList::append(), controller(), controllers(), dispatch(), dispatchers(), and QObject::objectName.

◆ uriForAction()

QString Dispatcher::uriForAction	(	Action *	action,
		const QStringList &	captures
	)		const

Takes a Catalyst::Action object and action parameters and returns a URI part such that if $c->req->path were this URI part, this action would be dispatched to with $c->req->captures set to the supplied arrayref.

If the action object is not available for external dispatch or the dispatcher cannot determine an appropriate URI, this method will return a null byte array.
