PHP Class lithium\console\Dispatcher

The console dispatcher is responsible for accepting requests from scripts called from the command line, and executing the appropriate Command class(es). The run() method accepts an instance of lithium\console\Request, which encapsulates the console environment and any command-line parameters passed to the script. Dispatcher then invokes lithium\console\Router to determine the correct Command class to invoke, and which method should be called.

Protected Properties

Property	Type	Description
$_classes	array	Class must implement a parse() method, which must return an array with (at a minimum) 'command' and 'action' keys.
$_rules	array	Each key in the array represents a 'rule'; if a key that matches the rule is present (and not empty) in a route, (i.e. the result of lithium\console\Router::parse()) then the rule's value will be applied to the route before it is dispatched. When applying a rule, any array elements array elements of the flag which are present in the route will be modified using a lithium\util\String::insert()-formatted string.

Public Methods

Method	Description
applyRules ( array $params ) : array	Attempts to apply a set of formatting rules from $_rules to a $params array.
config ( array $config = [] ) : array	Used to set configuration parameters for the Dispatcher.
run ( object $request = null, array $options = [] ) : object	Dispatches a request based on a request object (an instance of lithium\console\Request).

Protected Methods

Method	Description
_call ( string $callable, string $request, string $params ) : mixed	Calls a given command with the appropriate action.
_callable ( object $request, array $params, array $options ) : class	Determines which command to use for current request.

Method Details

_call() protected static method

This method is responsible for calling a $callable command and returning its result.

protected static _call ( string $callable, string $request, string $params ) : mixed
$callable	string	The callable command.
$request	string	The associated `Request` object.
$params	string	Additional params that should be passed along.
return	mixed	Returns the result of the called action, typically `true` or `false`.

_callable() protected static method

Determines which command to use for current request.

protected static _callable ( object $request, array $params, array $options ) : class
$request	object	An instance of a `Request` object.
$params	array	Request params that can be accessed inside the filter.
$options	array
return	class	lithium\console\Command Returns the instantiated command object.

applyRules() public static method

Each formatting rule is applied if the key of the rule in $_rules is present and not empty in $params. Also performs sanity checking against $params to ensure that no value matching a rule is present unless the rule check passes.

public static applyRules ( array $params ) : array
$params	array	An array of route parameters to which rules will be applied.
return	array	Returns the `$params` array with formatting rules applied to array values.

config() public static method

Used to set configuration parameters for the Dispatcher.

public static config ( array $config = [] ) : array
$config	array	Optional configuration params.
return	array	If no parameters are passed, returns an associative array with the current configuration, otherwise returns null.

run() public static method

If $request is null, a new request object is instantiated based on the value of the 'request' key in the $_classes array.

public static run ( object $request = null, array $options = [] ) : object
$request	object	An instance of a request object with console request information. If `null`, an instance will be created.
$options	array
return	object	The command action result which is an instance of `lithium\console\Response`.
