Detailed Description

This is the base class of a Cutelyst component

Definition at line 38 of file component.h.

Member Enumeration Documentation

enum Cutelyst::Component::Modifier

This value defines which kind of modifiers should be executed

Definition at line 45 of file component.h.

Constructor & Destructor Documentation

Component::Component ( QObject * parent = nullptr )

explicit

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

Definition at line 24 of file component.cpp.

Member Function Documentation

bool Component::afterExecute ( Context * c )

protectedvirtual

Reimplement this if you want to do processing after doExecute

Definition at line 132 of file component.cpp.

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

protected

Call this to install before, around and after roles

Definition at line 144 of file component.cpp.

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 114 of file component.cpp.

References aroundExecute(), doExecute(), QStack::pop(), and QVector::size().

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

bool Component::beforeExecute ( Context * c )

protectedvirtual

Reimplement this if you want to do processing before doExecute

Definition at line 108 of file component.cpp.

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 165 of file component.cpp.

bool Component::doExecute ( Context * c )

protectedvirtual

Reimplement this for the main processing

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

Definition at line 138 of file component.cpp.

Referenced by aroundExecute(), and execute().

bool Component::execute ( Context * c )

Executes this component agains the Context

Definition at line 75 of file component.cpp.

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

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

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 68 of file component.cpp.

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

Component::Modifiers Component::modifiers ( ) const

virtual

Reimplement to return custom Modifiers, default is None

Reimplemented in Cutelyst::Action, Cutelyst::View, and Cutelyst::RoleACL.

Definition at line 39 of file component.cpp.

QString Component::name ( ) const

Returns the sub name of this Component.

Definition at line 44 of file component.cpp.
