Detailed Description

SalvageableService defines an interface for services that are able to salvage state from a previous instance of the same class.

The intent is to allow new service instances to re-use resources that would be expensive to re-create, such as cached data or network connections.

Note: There is no expectation that services will be destroyed when the process (or web request) terminates.

Member Function Documentation

Wikimedia\Services\SalvageableService::salvage ( SalvageableService $other )

Re-uses state from $other.

$other must not be used after being passed to salvage(), and should be considered to be destroyed.

Note: Implementations are responsible for determining what parts of $other can be re-used safely. In particular, implementations should check that the relevant configuration of $other is the same as in $this before re-using resources from $other.; Implementations must take care to detach any re-used resources from the original service instance. If $other is destroyed later, resources that are now used by the new service instance must not be affected.; If $other is a DestructibleService, implementations should make sure that $other is in destroyed state after salvage finished. This may be done by calling $other->destroy() after carefully detaching all relevant resources.

Parameters

SalvageableService $other The object to salvage state from. $other must have the exact same type as $this.
