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 24 of file dispatcher.cpp.

References QObject::QObject(), and QObject::parent().

Referenced by controller(), controllers(), dispatchers(), expandAction(), forward(), getAction(), getActionByPath(), getActions(), prepareAction(), setupActions(), and uriForAction().

◆ ~Dispatcher()

Dispatcher::~Dispatcher ( )

Destroys the Dispatcher object.

Definition at line 32 of file dispatcher.cpp.

Member Function Documentation

◆ controller()

Controller * Dispatcher::controller ( QStringView name) const
nodiscard

Returns a Controller given it's name.

Definition at line 267 of file dispatcher.cpp.

References Dispatcher().

Referenced by setupActions().

◆ controllers()

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

Returns a list of registered controllers.

Definition at line 273 of file dispatcher.cpp.

References Dispatcher(), and 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 124 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
nodiscard

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 316 of file dispatcher.cpp.

References Dispatcher().

Referenced by setupActions().

◆ expandAction()

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

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 304 of file dispatcher.cpp.

References Dispatcher(), and 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 142 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 150 of file dispatcher.cpp.

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

◆ getAction()

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

Returns an action by name from a given nameSpace.

Definition at line 217 of file dispatcher.cpp.

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

◆ getActionByPath()

Action * Dispatcher::getActionByPath ( QStringView path) const
nodiscard

Returns an action by its full private path.

Definition at line 233 of file dispatcher.cpp.

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

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

◆ getActions()

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

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

Definition at line 246 of file dispatcher.cpp.

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

◆ prepareAction()

void Dispatcher::prepareAction ( Context * c)
protected

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

Definition at line 163 of file dispatcher.cpp.

References Dispatcher(), 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 37 of file dispatcher.cpp.

References Dispatcher(), controller(), controllers(), dispatch(), and dispatchers().

◆ uriForAction()

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

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.
