Class ExpireChanges<K>

org.springframework.data.redis.core.ExpireChanges<K>

public class ExpireChanges<K>
extends Object

Value Object linking a number of keys to their ExpireChanges.ExpiryChangeState retaining the order of the original source. Dedicated higher level methods interpret raw values retrieved from a Redis Client.

1. ok() returns keys for which the time to live has been set
2. expired() returns keys that have been expired
3. missed() returns keys for which the time to live could not be set because they do not exist
4. skipped() returns keys for which the time to live has not been set because a precondition was not met
