方法详细资料

create

public boolean create(double errorRate,
                      long capacity)

Creates an empty Bloom Filter with a given desired error ratio and initial capacity

参数:

errorRate - The desired probability for false positives. This should be a decimal value between 0 and 1.

capacity - The number of entries you intend to add to the filter

返回:

createAsync

public org.redisson.api.RFuture<Boolean> createAsync(double errorRate,
