Fluent

Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).

Allows user code to hook into Object::extend prior to control being delegated to extensions. Each callback will be reset once called.

Allows user code to hook into Object::extend after control being delegated to extensions. Each callback will be reset once called.

An implementation of the factory method, allows you to create an instance of a class

This method first for strong class overloads (singletons & DB interaction), then custom class overloads. If an overload is found, an instance of this is returned rather than the original class. To overload a class, use Object::useCustomClass()

This can be called in one of two ways - either calling via the class directly, or calling on Object and passing the class name as the first parameter. The following are equivalent: $list = DataList::create('SiteTree'); $list = SiteTree::get();

Creates a class instance by the "singleton" design pattern.

It will always return the same instance for this class, which can be used for performance reasons and as a simple way to access instance methods which don't rely on instance data (e.g. the custom SilverStripe static handling).

Create an object from a string representation. It treats it as a PHP constructor without the 'new' keyword. It also manages to construct the object without the use of eval().

Construction itself is done with Object::create(), so that Object::useCustomClass() calls are respected.

Object::create_from_string("Versioned('Stage','Live')") will return the result of Versioned::create('Stage', 'Live);

It is designed for simple, clonable objects. The first time this method is called for a given string it is cached, and clones of that object are returned.

If you pass the $firstArg argument, this will be prepended to the constructor arguments. It's impossible to pass null as the firstArg argument.

Object::create_from_string("Varchar(50)", "MyField") will return the result of Vachar::create('MyField', '50');

Arguments are always strings, although this is a quirk of the current implementation rather than something that can be relied upon.

Parses a class-spec, such as "Versioned('Stage','Live')", as passed to create_from_string().

Returns a 2-elemnent array, with classname and arguments

Similar to Object::create(), except that classes are only overloaded if you set the $strong parameter to TRUE when using Object::useCustomClass()

This class allows you to overload classes with other classes when they are constructed using the factory method Object::create()

If a class has been overloaded, get the class name it has been overloaded with - otherwise return the class name

Get the value of a static property of a class, even in that property is declared protected (but not private), without any inheritance, merging or parent lookup if it doesn't exist on the given class.

Return TRUE if a class has a specified extension.

This supports backwards-compatible format (static Object::has_extension($requiredExtension)) and new format ($object->has_extension($class, $requiredExtension))

Add an extension to a specific class.

The preferred method for adding extensions is through YAML config, since it avoids autoloading the class, and is easier to override in more specific configurations.

As an alternative, extensions can be added to a specific class directly in the Object::$extensions array. See SiteTree::$extensions for examples. Keep in mind that the extension will only be applied to new instances, not existing ones (including all instances created through singleton()).

Remove an extension from a class.

Keep in mind that this won't revert any datamodel additions of the extension at runtime, unless its used before the schema building kicks in (in your _config.php). Doesn't remove the extension from any Object instances which are already created, but will have an effect on new extensions. Clears any previously created singletons through singleton() to avoid side-effects from stale extension information.

Add support for removing extensions with parameters

Attemps to locate and call a method dynamically added to a class at runtime if a default cannot be located

You can add extra methods to a class using Extensions}, {@link Object::createMethod() or Object::addWrapperMethod()

Return TRUE if a method exists on this object

This should be used rather than PHP's inbuild method_exists() as it takes into account methods added via extensions

Return the names of all the methods available on this object

Adds any methods from Extension instances attached to this object.

All these methods can then be called directly on the instance (transparently mapped through __call()}), or called explicitly through {@link extend().

No description

Add all the methods from an object property (which is an Extension) to this object.

Add all the methods from an object property (which is an Extension) to this object.

Add a wrapper method - a method which points to another method with a different name. For example, Thumbnail(x) can be wrapped to generateThumbnail(x)

Add an extra method using raw PHP code passed as a string

Return true if this object "exists" i.e. has a sensible value

This method should be overriden in subclasses to provide more context about the classes state. For example, a DataObject class could return false when it is deleted from the database

No description

Check if this class is an instance of a specific class, or has that class as one of its parents

No description

Calls a method if available on both this object and all applied Extensions, and then attempts to merge all results into an array

integrate inheritance rules

Run the given function on all of this object's extensions. Note that this method originally returned void, so if you wanted to return results, you're hosed

Currently returns an array, with an index resulting every time the function is called. Only adds returns if they're not NULL, to avoid bogus results from methods just defined on the parent extension. This is important for permission-checks through extend, as they use min() to determine if any of the returns is FALSE. As min() doesn't do type checking, an included NULL return would fail the permission checks.

The extension methods are defined during __construct()} in {@link defineMethods().

Get an extension instance attached to this object by name.

Returns TRUE if this object instance has a specific extension applied in $extension_instances. Extension instances are initialized at constructor time, meaning if you use add_extension() afterwards, the added extension will just be added to new instances of the extended class. Use the static method has_extension() to check if a class (not an instance) has a specific extension.

Caution: Don't use singleton()->hasExtension() as it will give you inconsistent results based on when the singleton was first accessed.

Get all extension instances for this specific object instance.

See get_extensions() to get all applied extension classes for this class (not the instance).

Cache the results of an instance method in this object to a file, or if it is already cache return the cached results

Clears the cache for the given cacheToFile call

Loads a cache from the filesystem if a valid on is present and within the specified lifetime

Save a piece of cached data to the file system

Strip a file name of special characters so it is suitable for use as a cache file name

Forces regeneration of all locale routes

Initialise routes

Gets the current locale

Gets the locale requested directly in the request, either via route, post, or query parameters

Gets the locale currently set within either the session or cookie.

Specify the locale to persist between sessions, or to use for the locale outside of locale-routed pages (such as in unit tests, custom controllers, etc).

Not to be confused with the temporary locale assigned with {\Fluent::with_locale} .

Retrieves the list of locales

Retrieves the list of locale names as an associative array

Fetch a native language string from the i18n class via a passed locale in the format "XX_xx". In the event a match cannot be found in any framework resource, an empty string is returned.

Determine if the website is in domain segmentation mode

Retrieves any configured domains, assuming the site is running in domain mode.

Determine the home domain for this locale

Retrieves the default locale

Determines behaviour of locale filter in this request, by detecting whether to present an admin view of the site, or a frontend view.

If viewing in the CMS items filtered by locale will always be visible, but in the frontend will be filtered as expected.

For the sake of unit tests Fluent assumes a frontend execution environment.

Determine if a locale code is within the range of configured locales

Check if default locale should have prefix disabled

Helper function to check if the value given is present in any of the patterns.

This function is case sensitive by default.

Determine the alias to use for a specific locale

Determine the DB field name to use for the given base field

Installs the current locale into i18n

Determines the locale best matching the given list of browser locales

Executes a callback with a locale to temporarily emulate.

Warning: Existing DataObjects will contain fields in the actual locale if already lazily loaded, or if used within the callback, will populate itself with the overriding locale. The inverse will occur once the callback is complete. The best practice is to consider this a sandbox, and re-requery all objects required, discarding these afterwards.

Retrieves a search adapter for the current database adapter

Determine the baseurl within a specified $locale.

No description

Given a field on an object and optionally a locale, compare its locale value against the default locale value to determine if the value is changed at the given locale.

Sets whether to force "is_frontend" to return true or false. This can be used for situations where the frontend controllers are not involved, e.g. API modules, unit testing or retrieving data programmatically.
