CCodeGenerator is the base class for code generator classes.

CCodeGenerator is a controller that predefines several actions for code generation purpose. Derived classes mainly need to configure the codeModel property override the getSuccessMessage method. The former specifies which code model (extending CCodeModel) that this generator should use, while the latter should return a success message to be displayed when code files are successfully generated.

Property Details

codeModel property
public string $codeModel;

the code model class. This can be either a class name (if it can be autoloaded) or a path alias referring to the class file. Child classes must configure this property with a concrete value.

layout property
public string $layout;

the layout to be used by the generator. Defaults to 'generator'.

pageTitle property
public string getPageTitle()
public void setPageTitle(string $value)

the page title

templates property
public array $templates;

a list of available code templates (name=>path)

viewPath property
public string getViewPath()
public void setViewPath(string $value)

Returns the view path of the generator. The "views" directory under the directory containing the generator class file will be returned.
