controllers()

QMap< QString, Controller * > Dispatcher::controllers

(

)

const

Returns a hash of registered controllers

Definition at line 259 of file dispatcher.cpp.

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

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 293 of file dispatcher.cpp.

Referenced by setupActions().

expandAction()

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

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.

forward() [1/2]

bool Dispatcher::forward ( Context *  c, Component *  component  )

protected

Used by Application to forward execution to the following Component

forward() [2/2]

bool Dispatcher::forward ( Context *  c, const QString &  opname  )

protected

Used by Application to forward execution to opname that is resolved to an Action

Definition at line 141 of file dispatcher.cpp.

References Cutelyst::Action::dispatch().

getAction()

Action * Dispatcher::getAction	(	const QString &	name,
		const QString &	nameSpace = QString()
	)		const

Returns a named action from a given namespace.

Definition at line 206 of file dispatcher.cpp.

References getActionByPath().

getActionByPath()

Action * Dispatcher::getActionByPath

(

const QString &

path

)

const

Returns the named action by its full private path.

Definition at line 223 of file dispatcher.cpp.

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

getActions()

ActionList Dispatcher::getActions	(	const QString &	name,
		const QString &	nameSpace
	)		const

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

Definition at line 237 of file dispatcher.cpp.

prepareAction()

void Dispatcher::prepareAction ( Context *  c )

protected

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

Definition at line 154 of file dispatcher.cpp.

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 36 of file dispatcher.cpp.

References controllers(), dispatch(), dispatchers(), and Cutelyst::DispatchType::inUse().

uriForAction()

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

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.
