Entry.

query()

Look up a service for a given name in the container.

public query(T>|string $name[, bool $autoload = true ]) : T : mixed)

use self::get()

Parameters
$name : T>|string
$autoload : bool = true

Should we try to autoload the service. If we are trying to resolve built in types this makes no sense for example

throws
NotFoundExceptionInterface

if the name could not be found within the container

public registerAlias(string $alias, string $target) : void

use \OCP\AppFramework\Bootstrap\IRegistrationContext::registerServiceAlias

Parameters

registerService()

A service is registered in the container where a closure is passed in which will actually create the service on demand.

public registerService(string $name, callable(IContainer): mixed $closure[, bool $shared = true ]) : void

use \OCP\AppFramework\Bootstrap\IRegistrationContext::registerService

In case the parameter $shared is set to true (the default usage) the once created service will remain in memory and be reused on subsequent calls. In case the parameter is false the service will be recreated on every call.

Parameters
$name : string
$closure : callable(IContainer): mixed
$shared : bool = true
