* ProcessWire ConfigurableModule and ConfigModule Interfaces

*
* About the ConfigurableModule interface
* ======================================
* ConfigurableModule is an interface that indicates the module is configurable by providing
* `__get()` and `__set()` methods for getting and setting config values. Modules implementing
* this interface are assumed to also implement the `Module` interface.
*
* The module must also provide one (1) of the following:
*
* 1. A `getModuleConfigInputfields([$data])` method (static or non-static); OR
* 2. A separate `ModuleName.config.php` file that just populates $config array; OR
* 3. A separate `ModuleNameConfig.php` file that contains a ModuleConfig class.
*
* For more details about the above options, see the commented methods within
* the interface.
*
* When you use this as an interface, you MUST also use `Module` as an interface,
* i.e. `class Something implements Module, ConfigurableModule`
*
* Hint: Make your ConfigurableModule classes inherit from `WireData`, which already has
* the get/set required methods.
*
* You may optionally specify a handler method for configuration data: `setConfigData()`.
* If present, it will be used. See commented function reference in the interface below.
*
*
* About the ConfigModule interface (3.0.179+)
* ===========================================
* This interface indicates the module can receive config settings, but is not
* interactively configurable. Use this for modules where configuration will
* only be managed from the API/code side. Config settings must be saved using
* `$modules->saveConfig()`. Settings will be automatically populated to the module
* when it is loaded, or may be retrieved with `$modules->getConfig()`.
*
* Beyond the difference mentioned above, this interface is identical to the
* ConfigurableModule interface except that it needs no getModuleConfigInputfields()
* method nor will it use a configuration php or json file.
*
* A module *must not* contain both the ConfigModule and ConfigurableModule interfaces
* in their implements definition at the same time, so choose just one.
*
*

/**********************************************************************************
* getModuleConfigInputfields method (static or non-static)
*
* Return an InputfieldWrapper of Inputfields used to configure the class. This may
* be specified either as a static method or a non-static method.
*
* Benefits of static version
* ===========================
* 1. The module does not need to be instantiated in order to configure it, which
* means that unnecessary hooks won't get attached and unnecessary assets won't
* be triggered to load.
* 2. It is supported by all versions of ProcessWire.
*
* Drawbacks of static version
* ===========================
* 1. You cannot pull config values directly from the module since it isn't
* instantiated, and thus you must use the provided $data array. This $data array
* only contains values if the module has been configured before.
* 2. You can't access $this or anything you'd typically pull from it, like API vars
* or translation methods.
*
* Benefits of non-static version
* ==============================
* 1. You are working with the module in the same context that it is when running,
* thus you can pull config values and API vars directly from $this->something.
* 2. It can be extended in descending classes.
* 3. The $data argument can be omitted, as you don't need it since all config
* properties can be accessed directly from $this->[any property].
* 4. You can specify an optional $inputfields argument in your function definition
* and if present, ProcessWire will prepare an InputfieldWrapper for you, saving
* a step. When present, you can optionally omit the return statement at the
* bottom of the method as well.
*
* Drawbacks of non-static version
* ================================
* 1. It is supported only in ProcessWire versions 2.5.27 or newer.
* 2. The module must be instantiated in order to configure it, so it may trigger
* load of any used assets or attachment of any hooks unnecessarily.
*
* @param array $data Array of config values indexed by field name (static version only)
* Note that this array will be empty if the module has not been configured before.
* @return InputfieldWrapper

*
* // static version
* public static function getModuleConfigInputfields(array $data);
*
* // non-static version
* public function getModuleConfigInputfields();
*
* // non-static version with optional $data array, if you want it for some reason
* public function getModuleConfigInputfields(array $data);
*
* // non-static version with optional InputfieldWrapper as a convenience
* // note that the "return" statement may be omitted when using the $inputfields param.
* public function getModuleConfigInputfields($inputfields);

/*********************************************************************************
* Return an array defining Inputfields (static or non-static)
*
* You should use either getModuleConfigArray() or getModuleConfigInputfields(),
* do not use both, as ProcessWire will only recognize one or the other. Likewise,
* you should either use the static version of non-static version, not both.
*
* See notes for getModuleConfigInputfields() above for benefits and drawbacks
* of static vs. non-static versions. The primary difference between this method
* and that method is that this one returns an array. The format of the array should
* be as shown in InputfieldWrapper::importArray (see InputfieldWrapper.php).
*
* Whether static or non-static, your 'value' attributes in the array need only
* represent the default values. ProcessWire will populate the actual values
* to the resulting Inputfields after the method has been called. This is a benefit
* over the getModuleConfigInputfields() methods.
