方法详细资料

getDeletes

public List<K> getDeletes()

The keys that, when this diff is applied to a map, should be removed from the map.

返回:

the list of keys that are deleted

getDiffs

public Map<K,Diff<T>> getDiffs()

Map entries that, when this diff is applied to a map, should be incrementally updated. The incremental update is represented using the Diff interface.

返回:

the map entries that are incrementally updated

getUpserts

public Map<K,T> getUpserts()

Map entries that, when this diff is applied to a map, should be added to the map or fully replace the previous value.

返回:

the map entries that are additions or full updates
