Methods summary

`public static string`	# `format_model_name( string $module_id, string $model_id = 'primary' )` Formats a SQL table name given the module id and the model id. Formats a SQL table name given the module id and the model id. Parameters `$module_id` `$model_id` Returns string
`public`	# `__construct( array $paths, ICanBoogie\Storage\Storage $cache = null )` The index for the available modules is created with the accessor object. The index for the available modules is created with the accessor object. Parameters `$paths` The paths to look for modules. `$cache` The cache to use for the module indexes.
`protected`	# `revoke_constructions( )` Revokes constructions. Revokes constructions. The following properties are revoked: $enabled_modules_descriptors $disabled_modules_descriptors $catalog_paths $config_paths The method is usually invoked when modules state changes, in order to reflect these changes.
`public`	# `enable( string $module_id )` Enables a module. Enables a module. Parameters `$module_id` Module identifier.
`public`	# `disable( string $module_id )` Disables a module. Disables a module. Parameters `$module_id` Module identifier.
`public`	# `offsetSet( string $module_id, boolean $enable )` Used to enable or disable a module using the specified offset as a module identifier. Used to enable or disable a module using the specified offset as a module identifier. Parameters `$module_id` Identifier of the module. `$enable` Status of the module: `true` for enabled, `false` for disabled. Implementation of `ArrayAccess::offsetSet()`
`public`	# `offsetUnset( string $module_id )` Disables a module by setting the Descriptor::DISABLED key of its descriptor to `true`. Disables a module by setting the Descriptor::DISABLED key of its descriptor to `true`. Parameters `$module_id` Module identifier. Implementation of `ArrayAccess::offsetUnset()`
`public boolean`	# `offsetExists( string $module_id )` Checks the availability of a module. Checks the availability of a module. A module is considered available when its descriptor is defined, and the Descriptor::DISABLED key of its descriptor is empty. Note: `empty()` will call `ICanBoogie\Module\ModuleCollection::offsetGet()` to check if the value is not empty. So, unless you want to use the module you check, better check using `!isset()`, otherwise the module you check is loaded too. Parameters `$module_id` Module identifier. Returns boolean Whether or not the module is available. Implementation of `ArrayAccess::offsetExists()`
`public ICanBoogie\Module`	# `offsetGet( string $module_id )` Returns a module object. Returns a module object.
