* Controller is the base class of console command classes.
|
|
*
|
|
* A console controller consists of one or several actions known as sub-commands.
|
|
* Users call a console command by specifying the corresponding route which identifies a controller action.
|
|
* The `yii` program is used when calling a console command, like the following:
|
|
*
|
|
* ```
|
|
* yii <route> [--param1=value1 --param2 ...]
|
|
* ```
|
|
*
|
|
* where `<route>` is a route to a controller action and the params will be populated as properties of a command.
|
|
* See [[options()]] for details.
|
|
*
|
|
* @property-read string $helpSummary The one-line short summary describing this controller.
|
|
* @property-read array $passedOptionValues The properties corresponding to the passed options.
|
|
* @property-read array $passedOptions The names of the options passed during execution.
|
|
* @property Request $request
