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().

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.

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.

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(), and getActionByPath().

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().

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().

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(), 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.
