Package com.hazelcast.cache
Interface CacheEvictionPolicyComparator<K,V>
- Type Parameters:
K
- type of the keyV
- type of the value
- All Superinterfaces:
Comparator<CacheEntryView<K,
,V>> EvictionPolicyComparator<K,
,V, CacheEntryView<K, V>> Serializable
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface
public interface CacheEvictionPolicyComparator<K,V>
extends EvictionPolicyComparator<K,V,CacheEntryView<K,V>>
ICache
specific EvictionPolicyComparator
for comparing CacheEntryView
s to be evicted.
Implementors of the comparator have to implement equals
and hashCode
methods
to support correct config comparison.- See Also:

instances and returns the result. The result should be one of- -1: first entry has higher priority to be evicted
- 1: second entry has higher priority to be evicted
- 0: both entries have same priority
- Specified by:
compare
in interfaceComparator<K>
- Parameters:
o1
- the firstCacheEntryView
instance to be comparedo2
