Detailed Description

This class represents a Cutelyst Action.

It encapsulates a Controller method that was defined with C_ATTR macro, it's usually automatically created by Cutelyst::Controller using it's introspections information, this class allows Cutelyst to call a Controller method.

You can access the object for the currently dispatched action via c->action(). See the Cutelyst::Dispatcher for more information on how actions are dispatched.

Constructor & Destructor Documentation

◆ Action()

Action::Action ( QObject * parent = nullptr )

explicit

Constructs a Action object with the given parent.

Definition at line 12 of file action.cpp.

Member Function Documentation

◆ attribute()

QString Action::attribute	(	const QString &	name,
		const QString &	defaultValue = `{}`
	)		const

Returns the value attribute by it's name, if not found dafault value is returned.

Attributes can be defined using the C_ATTR macro on Controller's method declaration.

Definition at line 74 of file action.cpp.

References Cutelyst::Component::name().

Referenced by Cutelyst::DispatchTypeChained::expandAction().

◆ attributes()

ParamsMultiMap Action::attributes ( ) const

noexcept

Returns the attributes that are set for this action, like Local, Path, Private and so on. This determines how the action is dispatched to.

◆ className()

QString Action::className ( ) const

Returns the name of the component where this action is defined

Definition at line 86 of file action.cpp.

◆ controller()

Controller * Action::controller ( ) const

Returns the controller where this action is defined

Referenced by Cutelyst::Dispatcher::dispatch(), and setController().

◆ dispatch()

bool Cutelyst::Action::dispatch ( Context * c )

inline

Dispatch this action against a context

References Cutelyst::Context::execute().

Referenced by Cutelyst::Controller::_DISPATCH(), Cutelyst::ActionChain::doExecute(), and Cutelyst::Dispatcher::forward().

◆ doExecute()

bool Action::doExecute ( Context * c )

overrideprotectedvirtual

Execute this action against

Reimplemented from Cutelyst::Component.

Reimplemented in Cutelyst::ActionChain, Cutelyst::RenderView, and Cutelyst::ActionREST.

Referenced by Cutelyst::ActionREST::doExecute(), and Cutelyst::RenderView::doExecute().

◆ match()

bool Action::match ( int numberOfArgs ) const

virtualnoexcept

Check Args attribute, and makes sure number of args matches the setting. Always returns true if Args is omitted.

Definition at line 98 of file action.cpp.

◆ matchCaptures()

bool Action::matchCaptures ( int numberOfCaptures ) const

virtualnoexcept

Can be implemented by action class and action role authors. If the method exists, then it will be called with the request context and an array reference of the captures for this action.

Returns: Returning true from this method causes the chain match to continue, returning false makes the chain not match (and alternate, less preferred chains will be attempted).

Definition at line 108 of file action.cpp.

◆ modifiers()

Component::Modifiers Action::modifiers ( ) const

overridevirtual

Reimplement to return custom Modifiers, default is None

Reimplemented from Cutelyst::Component.

Definition at line 22 of file action.cpp.

◆ ns()

QString Action::ns ( ) const

noexcept

Returns the private namespace this action lives in.

Definition at line 118 of file action.cpp.

◆ numberOfArgs()

qint8 Action::numberOfArgs ( ) const

virtualnoexcept

Returns the number of args this action expects. This is 0 if the action doesn't take any arguments and undef if it will take any number of arguments.

Definition at line 124 of file action.cpp.

◆ numberOfCaptures()

qint8 Action::numberOfCaptures ( ) const

virtualnoexcept

Returns the number of captures this action expects for Chained actions.

Reimplemented in Cutelyst::ActionChain.
