方法详细资料

create

public boolean create(int width,
                      int depth)

Initializes a Count-Min Sketch

参数:

width - Number of counter in each array

depth - Number of counter-arrays

返回:

createAsync

public org.redisson.api.RFuture<Boolean> createAsync(int width,
                                                     int depth)

create

public boolean create(double errorRadio,
                      double probability)

Initializes a Count-Min Sketch.

参数:

errorRadio - Estimate size of error. The error is a percent of total counted items

probability - The desired probability for inflated count. This should be a decimal value between 0 and 1

返回:

createAsync

public org.redisson.api.RFuture<Boolean> createAsync(double errorRadio,
                                                     double probability)

incrby

public List<Integer> incrby(String[] items,
                            int[] increments)

Increases the count of item by increment.

参数:

items -

increments -

返回:

incrbyAsync

public org.redisson.api.RFuture<List<Integer>> incrbyAsync(String[] items,
                                                           int[] increments)

query

public List<Integer> query(String... items)

query count for item

参数:

items - The items which counter to be increased

返回:

Count of one or more items

queryAsync

public org.redisson.api.RFuture<List<Integer>> queryAsync(String... items)

merge

public boolean merge(int keyNum,
                     String[] srcs,
                     Integer[] weights)

Merges several sketches into one sketch.

参数:

keyNum - Number of sketches to be merged

srcs - Names of source sketches to be merged

weights - Multiple of each sketch. Default =1

返回:

mergeAsync

public org.redisson.api.RFuture<Boolean> mergeAsync(int keyNum,
                                                    String[] srcs,
                                                    Integer[] weights)

getInfo

public CountMinSketchInfo getInfo()

返回:

width, depth and total count of the sketch

getInfoAsync

public org.redisson.api.RFuture<CountMinSketchInfo> getInfoAsync()
