static array getSubscribedServices()

Returns an array of service types required by such instances, optionally keyed by the service names used internally.

For mandatory dependencies:

• array('logger' => 'Psr\Log\LoggerInterface') means the objects use the "logger" name internally to fetch a service which must implement Psr\Log\LoggerInterface.
• array('Psr\Log\LoggerInterface') is a shortcut for
• array('Psr\Log\LoggerInterface' => 'Psr\Log\LoggerInterface')

otherwise:

• array('logger' => '?Psr\Log\LoggerInterface') denotes an optional dependency
• array('?Psr\Log\LoggerInterface') is a shortcut for
• array('Psr\Log\LoggerInterface' => '?Psr\Log\LoggerInterface')

Return Value

array

The required service types, optionally keyed by service names
