Details
bool
isOptional()
Checks whether this warmer is optional or not.
Optional warmers can be ignored on certain conditions.
A warmer should return true if the cache can be generated incrementally and on-demand.
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('loggers' => 'Psr\Log\LoggerInterface[]') means the objects use the "loggers" name internally to fetch an iterable of Psr\Log\LoggerInterface instances.
- 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('loggers' => '?Psr\Log\LoggerInterface[]') denotes an optional iterable dependency
- array('?Psr\Log\LoggerInterface') is a shortcut for
- array('Psr\Log\LoggerInterface' => '?Psr\Log\LoggerInterface')
