Returns the current count of events in the queue up to the reference time based on which count based evictions can be performed.

指定者:

getCurrentCount 在接口中 EvictionContext

返回:

the current count

getSlidingCount

public Long getSlidingCount()

从接口复制的说明: EvictionContext

Returns the sliding count for count based windows.

指定者:

getSlidingCount 在接口中 EvictionContext

返回:

the sliding count

getSlidingInterval

public Long getSlidingInterval()

从接口复制的说明: EvictionContext

Returns the sliding interval for time based windows.

指定者:

getSlidingInterval 在接口中 EvictionContext

返回:

the sliding interval
