Detailed Description

This is the base class of a Cutelyst component.

Logging category: cutelyst.component
Logging with Cutelyst

Definition at line 29 of file component.h.

Member Enumeration Documentation

◆ Modifier

enum Cutelyst::Component::Modifier

This value defines which kind of modifiers should be executed.

Definition at line 36 of file component.h.

Constructor & Destructor Documentation

◆ Component() [1/2]

Component::Component ( QObject * parent = nullptr )

explicit

This is the base class for many Cutelyst objects, providing access to name and reverse for actions, and modifiers to customize execution.

Definition at line 11 of file component.cpp.

◆ ~Component()

Component::~Component ( )

overridevirtual

Destroys the Component object.

Definition at line 23 of file component.cpp.

◆ Component() [2/2]

Component::Component	(	ComponentPrivate *	d,
		QObject *	parent = `nullptr`
	)

explicitprotected

A derived class using pimpl should call this constructor, to reduce the number of memory allocations.

Definition at line 17 of file component.cpp.

Member Function Documentation

◆ afterExecute()

bool Component::afterExecute ( Context * c )

protectedvirtual

Reimplement this if you want to do processing after doExecute().

Definition at line 121 of file component.cpp.

◆ applyRoles()

void Component::applyRoles ( const QStack< Component * > & roles )

protected

Call this to install before, around and after roles.

Definition at line 133 of file component.cpp.

◆ aroundExecute()

bool Component::aroundExecute	(	Context *	c,
		QStack< Component * >	stack
	)

protectedvirtual

Reimplement this if you want to do processing around doExecute(), you must call doExecute() yourself then.

Reimplemented in Cutelyst::RoleACL.

Definition at line 103 of file component.cpp.

References aroundExecute(), doExecute(), QStack::pop(), Cutelyst::Context::req, and QList::size().

Referenced by aroundExecute(), Cutelyst::RoleACL::aroundExecute(), and execute().

◆ beforeExecute()

bool Component::beforeExecute ( Context * c )

protectedvirtual

Reimplement this if you want to do processing before doExecute().

Definition at line 97 of file component.cpp.

◆ dispatcherReady()

bool Component::dispatcherReady	(	const Dispatcher *	dispatch,
		Controller *	controller
	)

protectedvirtual

Called by dispatcher once it’s done preparing actions.

Subclasses might want to implement this to cache special actions, such as special methods for REST actions.

Reimplemented in Cutelyst::RoleACL.

Definition at line 154 of file component.cpp.

◆ doExecute()

bool Component::doExecute ( Context * c )

protectedvirtual

Reimplement this for the main processing.

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

Definition at line 127 of file component.cpp.

Referenced by aroundExecute(), and execute().

◆ execute()

bool Component::execute ( Context * c )

Executes this component agains the Context c.

Definition at line 64 of file component.cpp.

References aroundExecute(), doExecute(), and QList::push_front().

Referenced by Cutelyst::Context::execute().

◆ init()

bool Component::init	(	Cutelyst::Application *	application,
		const QVariantHash &	args
	)

virtual

A Does class is always attached to an action, if this method returns false, the application will fail to start. Often useful if the user misconfigured the settings.

Reimplemented in Cutelyst::RoleACL, and Cutelyst::RenderView.

Definition at line 57 of file component.cpp.

Referenced by Cutelyst::RenderView::init(), and Cutelyst::Action::setupAction().
