MvcTools::ezcMvcRailsRoute

Class ezcMvcRailsRoute

Router class that uses rails style expressions for matching routes.

The routes are matched against the uri property of the request object. The matching algorithm works as follows:

The pattern and URI as returned by getUriString() are split on the / character.
If the first part of the split *pattern* contains a "." (dot) then the first part of the pattern and the URI are split by ".". The return of this, together with the rest of the original split-by-slash string are concatenated.
Each of the two arrays are compared with each other with the delimiters being ignored.
A special case are elements in the pattern that start with a ":". In this case the pattern element and uri element do not need to match. Instead the pattern element creates a named variable with as value the element from the URI array with the same index.
If not every element matches, the route does not match and false is returned. If everything matches, true is returned.

Member Variables

protected string	`$action` Contains the action that the controller should execute.
protected string	`$controllerClassName` This is the name of the controller class that will be instantiated with the request variables obtained from the route, as well as the default values belonging to a route.
protected array(string)	`$defaultValues` The default values for the variables that are send to the controller. The route matchers can override those default values
protected string	`$pattern` This property contains the pattern

Method Summary

public ezcMvcRailsRoute	`__construct( $pattern , $controllerClassName , [ $action = null] , [ $defaultValues = array()] )` Constructs a new ezcMvcRailsRoute with $pattern.
public void	`generateUrl( [ $arguments = null] )` Generates an URL back out of a route, including possible arguments
protected string	`getUriString( $request )` Returns the request information that the matches() method will match the pattern against.
protected bool	`match( $request , &$matches , $matches )` This method performs the actual pattern match against the $request's URI.
public null\|ezcMvcRoutingInformation	`matches( $request )` Evaluates the URI against this route.
public void	`prefix( $prefix )` Adds the $prefix to the route's pattern.

Methods

__construct

ezcMvcRailsRoute __construct( string $pattern , string $controllerClassName , [string $action = null] , [ $defaultValues = array()] )

Constructs a new ezcMvcRailsRoute with $pattern.

When the route is matched (with the match() method), the route instantiates an object of the class $controllerClassName.

Parameters:

Name	Type	Description
`$pattern`	string
`$controllerClassName`	string
`$action`	string
`$defaultValues`	array(string)

generateUrl

void generateUrl( [ $arguments = null] )

Generates an URL back out of a route, including possible arguments

Parameters:

Name	Type	Description
`$arguments`	array

Implementation of:

Method	Description
`ezcMvcReversibleRoute::generateUrl()`	Generates an URL back out of a route, including possible arguments

getUriString

string getUriString( ezcMvcRequest $request )

Returns the request information that the matches() method will match the pattern against.

Parameters:

Name	Type	Description
`$request`	ezcMvcRequest

match

bool match( ezcMvcRequest $request , &$matches , array(string) $matches )

This method performs the actual pattern match against the $request's URI.

Parameters:

Name	Type	Description
`$request`	ezcMvcRequest
`$matches`	array(string)
`&$matches`

matches

null|ezcMvcRoutingInformation matches( ezcMvcRequest $request )

Evaluates the URI against this route.

The method first runs the match. If the pattern matches, it then creates an object containing routing information and returns it. If the route's pattern did not match it returns null.

Parameters:

Name	Type	Description
`$request`	ezcMvcRequest

Implementation of:

Method	Description
`ezcMvcRoute::matches()`	Returns routing information if the route matched, or null in case the route did not match.

prefix

void prefix( mixed $prefix )

Adds the $prefix to the route's pattern.

It's up to the developer to provide a meaningfull prefix. In this case, it needs to be a pattern just like the normal pattern.

Parameters:

Name	Type	Description
`$prefix`	mixed

Implementation of:

Method	Description
`ezcMvcRoute::prefix()`	Adds a prefix to the route.
