Methods summary


				
				 public static
				
				

				format_model_name( string $module_id, string $model_id = 'primary' )
				

				: string

Formats a SQL table name given the module id and the model id.


				
				 public 
				
				

				__construct( array $paths, ICanBoogie\Storage\StorageInterface $cache = null )

The index for the available modules is created with the accessor object.


				
				 protected 
				
				

				revoke_constructions( void )

Revokes constructions.


				
				 public 
				
				

				enable( string $id )

Enables a module.


				
				 public 
				
				

				disable( string $id )

Disables a module.


				
				 public 
				
				

				offsetSet( mixed $id, mixed $enable )

Used to enable or disable a module using the specified offset as the module's id.

The module is enabled or disabled by modifying the value of the Descriptor::DISABLED key of the module's descriptor.

Parameters

$id: Identifier of the module.
$enable: Status of the module: true for enabled, false for disabled.

Implementation of

ArrayAccess::offsetSet()


				
				 public 
				
				

				offsetExists( string $id )
				

				: boolean

Checks the availability of a module.

A module is considered available when its descriptor is defined, and the Descriptor::DISABLED key of its descriptor is empty.

Note: empty() will call ICanBoogie\Module\ModuleCollection::offsetGet() to check if the value is not empty. So, unless you want to use the module you check, better check using !isset(), otherwise the module you check is loaded too.

Parameters

$id: Identifier of the module.

Returns

boolean
Whether or not the module is available.

Implementation of

ArrayAccess::offsetExists()


				
				 public 
				
				

				offsetUnset( string $id )

Disables a module by setting the Descriptor::DISABLED key of its descriptor to true.

The method also dismisses the enabled_modules_descriptors and disabled_modules_descriptors properties.

Parameters

$id: Identifier of the module.

Implementation of

ArrayAccess::offsetUnset()


				
				 public 
				
				

				offsetGet( string $id )
				

				: ICanBoogie\Module

Returns a module object.

If the autorun property is true, the ICanBoogie\Module\Module::run() method of the module is invoked upon its first loading.

Parameters

$id: The identifier of the module.

Returns

ICanBoogie\Module

Throws

ICanBoogie\Module\ModuleNotDefined
when the requested module is not defined.
ICanBoogie\Module\ModuleIsDisabled
when the module is disabled.
ICanBoogie\Module\ModuleConstructorMissing

when the class that should be used to create its instance is not defined.

Implementation of

ArrayAccess::offsetGet()


				
				 public 
				
				

				getIterator( void )
				

				: ArrayIterator

Returns an iterator for the modules.


				
				 protected 
				
				

				lazy_get_index( void )
				

				: array

Indexes the modules found in the paths specified during construct.

The index is made of an array of descriptors, an array of catalogs paths, an array of configs path, and finally an array of configs constructors.

The method also creates a DIR constant for each module. The constant is defined in the namespace of the module e.g. Icybee\ModuleCollection\Nodes\DIR.

Returns

array


				
				 protected 
				
				

				index_construct( void )
				

				: array

Construct the index for the modules.

The index contains the following values:

(array) descriptors: The descriptors of the modules, ordered by weight.
(array) catalogs: Absolute paths to locale catalog directories.
(array) configs: Absolute paths to config directories.
(array) classes aliases: An array of key/value pairs where key is the alias of a class and value if the real class.

Returns

array


				
				 protected 
				
				

				index_descriptors( array $paths )
				

				: array[string]array

Indexes descriptors.

The descriptors are extended with the following default values:

(string) category: null.
(string) class: ModuleCollection\
(string) description: null.
(bool) disabled: false if required, true otherwise.
(string) extends: null.
(string) id: The module's identifier.
(array) models: Empty array.
(string) path: The absolute path to the module directory.
(string) permission: null.
(array) permissions: Empty array.
(bool) startup: false.
(bool) required: false.
(array) requires: Empty array.
(string) weight: 0.

The descriptors are ordered according to their inheritance and weight.

Parameters

$paths

Returns

array[string]array


				
				 protected 
				
				

				collect_descriptors( array $paths )


				
				 protected 
				
				

				read_descriptor( string $id, string $path )
				

				: array

Reads the descriptor file.

The descriptor file is extended with private values and default values.

Parameters

$id: The identifier of the module.
$path: The path to the directory where the descriptor is located.

Returns

array

Throws

InvalidArgumentException

in the following situations: - The descriptor is not an array - The Descriptor::TITLE key is empty. - The Descriptor::NS key is empty.


				
				 protected 
				
				

				alter_descriptor( array $descriptor )
				

				: array

Alters the module descriptor.


				
				 protected 
				
				

				lazy_get_disabled_modules_descriptors( void )
				

				: array

Returns the descriptors of the disabled modules.


				
				 protected 
				
				

				lazy_get_enabled_modules_descriptors( void )
				

				: array

Returns the descriptors of the enabled modules.


				
				 protected 
				
				

				lazy_get_locale_paths( void )
				

				: array[]string

Returns the paths of the enabled modules which have a locale folder.


				
				 protected 
				
				

				lazy_get_config_paths( void )
				

				: array[]string

Returns the paths of the enabled modules which have a config folder.


				
				 public 
				
				

				order_ids( array $ids, array $descriptors = null )
				

				: array

Orders the module ids provided according to module inheritance and weight.


				
				 public 
				
				

				usage( string $module_id, boolean $all = false )
				

				: integer

Returns the usage of a module by other modules.

Parameters

$module_id: The identifier of the module.
$all: The usage is only computed for enabled module, this parameter can be used to compute the usage with disabled modules also.

Returns

integer


				
				 public 
				
				

				is_inheriting( string $module_id, string $parent_id )
				

				: boolean

Checks if a module inherits from another.


				
				 public 
				
				

				is_extending( string $module_id, string $extending_id )
				

				: boolean


				
				 public 
				
				

				install( ICanBoogie\Errors $errors )
				

				: ICanBoogie\Errors

Install all the enabled modules.


				
				 public 
				
				

				resolve_classname( string $unqualified_classname, string|ICanBoogie\Module $module )
				

				: string|false

Resolves a class name using module inheritance.

To resolve a given class name, the method checks in each module namespace—starting from the specified module—if the class exists. If it does, it returns its fully qualified name.

Parameters

$unqualified_classname
$module

Returns

string|false
The resolved file name, or false if it could not be resolved.

Throws

ICanBoogie\Module\ModuleNotDefined

if the specified module, or the module specified by Descriptor::INHERITS is not defined.
