What does the resolved mentioned in the laravel container mean.

{Code...} I saw it when reading laravel source code. It is located in IlluminateContainerContainer. Is this resolved used to mark whether the corresponding type name has been parsed? Translation of resolved in youdao dictionary ....

/** * An array of the types that have been resolved. * * @var array */protected $resolved = array();

Read the laravel source code.
Located in Illuminate \ Container.

Is this resolved used to mark whether the corresponding type name has been resolved?

Resolved translation in youdao dictionary.
Adj. Made up your mind; resolved; flatly
V. solution; decision; decomposition; Transformation (past word segmentation of resolve)

Yes.

You tracked this variable.

public function make($abstract, $parameters = array()){    $abstract = $this->getAlias($abstract);    $this->resolved[$abstract] = true;

It seems that this variable is the only place in the Framework ....

It's a counter, no more.

View::make(...),App::make('foo')

$resolved = array('view'=>true,'foo'=>true);

Is it estimated that there is a problem to facilitate debugging?

We know that there are a lot of Facade usage in Laravel, such as the router you wrote at the beginning, Router: get (). Do you know why you can write it like this? Router: get () is equivalent to $ app-> make ('router ')-> get (); $ app-> make ('router ') it is an image-like ioc container, $ app-> make () is the container, and 'router 'is the class (alias) that is put into resolution ), $ app-> make ('router ') can put an instance of the Route classAnalysis.

You may ask whyAnalysisWhat about it? What does parsing mean? Can I get an instance for the New class? First, if you bind a class to the Ioc container, it can automatically generate instances for you without the need to include or use new. Next, a new class cannot directly parse the class it depends on, especially the interface class. To use the new method, you must first create an instance with the new method, then input the dependent instance (meaning there are more new instances ).
