This is the base class for all generator classes.

A generator instance is responsible for taking user inputs, validating them, and using them to generate the corresponding code based on a set of code template files.

A generator class typically needs to implement the following methods:

  • {@see \Yiisoft\Yii\Gii\GeneratorInterface::getName()}: returns the name of the generator
  • {@see \Yiisoft\Yii\Gii\GeneratorInterface::getDescription()}: returns the detailed description of the generator
  • {@see \Yiisoft\Yii\Gii\GeneratorInterface::generate()}: generates the code based on the current user input and the specified code template files. This is the place where main code generation code resides.
