FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package class-instantiator
Class Instantiator
The class instantiator tries to create an object of the passed class recursively.
Some arguments for a constructor cannot be created automatically.
For example primitive types like integer or interfaces.
Or you want to inject a specific object, that should not be created automatically, like a PDO object.
For those scenarios, there are multiple solutions.
Pass predefined arguments:
Extend the class instantiator:
Use an attribute to define a class instantiator extension:
Instantiate classes with an extension has a higher priority then using an attribute.
This allows overwriting the attribute and instantiate classes depending on your current needs.
You can also use the instantiator attribute to let the class build from a method in a specific instantiator:
The attribute can also be used on a constructor parameter:
The attribute on the parameter has a higher priority as the one on the class itself.
It is also possible to specify a method of the instantiator in the attribute.
Storing Objects
It is possible to sore objects permanently with an attribute.
Those objects will then be returned when a matching class is requested instead of creating a new one every time.
Storing objects with attribute does not work when the instantiation is done in the extension.
This is because of the higher priority for extensions.
But you can store objects as well when using the method "injectObject" inside the creation method of the extension.
Inject Objects
It is possible to inject objects into the class instantiator.
Those objects will be returned when a matching class is requested.
PSR-11 Container
There is also a PSR-11 Container Implementation.
You can use this container in frameworks and libraries who support those.
