BootstrapInterface
in
BootstrapInterface is the interface that should be implemented by classes who want to participate in the application bootstrap process.
The main method [[bootstrap()]] will be invoked by an application at the beginning of its init() method.
Bootstrapping classes can be registered in two approaches.
The first approach is mainly used by extensions and is managed by the Composer installation process.
You mainly need to list the bootstrapping class of your extension in the composer.json file like following,
{
// ...
"extra": {
"bootstrap": "path\\to\\MyBootstrapClass"
}
}
If the extension is installed, the bootstrap information will be saved in [[Application::extensions]].
The second approach is used by application code which needs to register some code to be run during the bootstrap process. This is done by configuring the [[Application::bootstrap]] property:
return [
// ...
'bootstrap' => [
"path\\to\\MyBootstrapClass1",
[
'class' => "path\\to\\MyBootstrapClass2",
'prop1' => 'value1',
'prop2' => 'value2',
],
],
];
As you can see, you can register a bootstrapping class in terms of either a class name or a configuration class.
