getActiveRequestHandler ( ) : Neos\Flow\Core\RequestHandlerInterface	Returns the request handler (if any) which is currently handling the request.
getContext ( ) : ApplicationContext	Returns the context this bootstrap was started in.
getEarlyInstance ( string $objectName ) : object	Returns an instance which was registered earlier through setEarlyInstance()
getEarlyInstances ( ) : array	Returns all registered early instances indexed by object name

isCompiletimeCommand ( string $commandIdentifier ) : boolean	Tells if the given command controller is registered for compiletime or not.
registerCompiletimeCommand ( string $commandIdentifier ) : void	Registers a command specified by the given identifier to be called during compiletime (versus runtime). The related command controller must be totally aware of the limited functionality Flow provides at compiletime.
registerRequestHandler ( Neos\Flow\Core\RequestHandlerInterface $requestHandler ) : void	Registers a request handler which can possibly handle a request.
run ( ) : void	Bootstraps the minimal infrastructure, resolves a fitting request handler and then passes control over to that request handler.

setEarlyInstance ( string $objectName, object $instance ) : void	Registers the instance of the specified object for an early boot stage.
setPreselectedRequestHandlerClassName ( string $className )	Preselects a specific request handler. If such a request handler exists, it will be used if it can handle the request – regardless of the priority of this or other request handlers.
shutdown ( string $runlevel ) : void	Initiates the shutdown procedure to safely close all connections, save modified data and commit other tasks necessary to cleanly exit Flow.

Protected Methods

Method	Description
defineConstants ( ) : void	Defines various path constants used by Flow and if no root path or web root was specified by an environment variable, exits with a respective error message.

defineConstants() protected method

Defines various path constants used by Flow and if no root path or web root was specified by an environment variable, exits with a respective error message.

protected defineConstants ( ) : void
return	void

emitBootstrapShuttingDown() protected method

Emits a signal that the bootstrap finished and is shutting down.

protected emitBootstrapShuttingDown ( string $runLevel ) : void
$runLevel	string
return	void

emitFinishedCompiletimeRun() protected method

Emits a signal that the compile run was finished.

protected emitFinishedCompiletimeRun ( ) : void
return	void

emitFinishedRuntimeRun() protected method

Emits a signal that the runtime run was finished.

protected emitFinishedRuntimeRun ( ) : void
return	void

ensureRequiredEnvironment() protected method

Checks PHP version and other parameters of the environment

protected ensureRequiredEnvironment ( ) : void
return	void

getActiveRequestHandler() public method

Returns the request handler (if any) which is currently handling the request.

public getActiveRequestHandler ( ) : Neos\Flow\Core\RequestHandlerInterface
return	Neos\Flow\Core\RequestHandlerInterface

getContext() public method

Returns the context this bootstrap was started in.

public getContext ( ) : ApplicationContext
return	ApplicationContext	The context encapsulated in an object, for example "Development" or "Development/MyDeployment"

getEarlyInstance() public method

Returns an instance which was registered earlier through setEarlyInstance()

public getEarlyInstance ( string $objectName ) : object
$objectName	string	Object name of the registered instance
return	object

getEarlyInstances() public method

Returns all registered early instances indexed by object name

public getEarlyInstances ( ) : array
return	array

getEnvironmentConfigurationSetting() public static method

- getenv with $variableName - getenv with REDIRECT_ . $variableName (this is for php cgi where environment variables from the http server get prefixed) - $_SERVER[$variableName] (this is an alternative to set FLOW_* environment variables if passing environment variables is not possible) - $_SERVER[REDIRECT_ . $variableName] (again for php cgi environments)

public static getEnvironmentConfigurationSetting ( string $variableName ) : string
$variableName	string
return	string	or NULL if this variable was not set at all.

getObjectManager() public method

Returns the object manager instance

public getObjectManager ( ) : Neos\Flow\ObjectManagement\ObjectManagerInterface
return	Neos\Flow\ObjectManagement\ObjectManagerInterface

return	Neos\Flow\Persistence\PersistenceManagerInterface

isCompiletimeCommand() public method

Tells if the given command controller is registered for compiletime or not.

public isCompiletimeCommand ( string $commandIdentifier ) : boolean
$commandIdentifier	string	Package key, controller name and command name separated by colon, e.g. "neos.flow:cache:flush"
return	boolean

return	void

resolveRequestHandler() protected method

Iterates over the registered request handlers and determines which one fits best.

protected resolveRequestHandler ( ) : Neos\Flow\Core\RequestHandlerInterface
return	Neos\Flow\Core\RequestHandlerInterface	A request handler

run() public method

Bootstraps the minimal infrastructure, resolves a fitting request handler and then passes control over to that request handler.

public run ( ) : void
return	void

setActiveRequestHandler() public method

This method makes only sense to use during functional tests. During a functional test run the active request handler chosen by the bootstrap will be a command line request handler specialized on running functional tests. A functional test case can then set the active request handler to one which simulates, for example, an HTTP request.

public setActiveRequestHandler ( Neos\Flow\Core\RequestHandlerInterface $requestHandler ) : void
$requestHandler	Neos\Flow\Core\RequestHandlerInterface
return	void

setEarlyInstance() public method

$objectName	string	Object name, as later used by the Object Manager
$instance	object	The instance to register
return	void

setPreselectedRequestHandlerClassName() public method

Preselects a specific request handler. If such a request handler exists, it will be used if it can handle the request – regardless of the priority of this or other request handlers.

public setPreselectedRequestHandlerClassName ( string $className )
$className	string

shutdown() public method

This method should be called by a request handler after a successful run. Control is returned to the request handler which can exit the application as it sees fit.

public shutdown ( string $runlevel ) : void
$runlevel	string	one of the RUNLEVEL_* constants
return	void
