                             double rate)

Return a random sampler, with specific random instance, and rate

参数:

random - the random instance

rate - the rate to do really operation, should be [0,1]

抛出:

java.lang.IllegalArgumentException - if rate value is illegal

roundRobin

public static Sampler roundRobin(double rate)

Return a sampler sample by round robin

参数:

rate - the rate to do really operation, should be [0,1]

抛出:

java.lang.IllegalArgumentException - if rate value is illegal

run

public void run(java.lang.Runnable runnable)
