org.teasoft.honey.distribution.SerialUniqueId Serial Unique Id in one workerid. Advantages:continuous and unique;less clock dependent.Implemented in dB, it can achieve auto increment of distributed global unique ID in dB. The ID number get in the same workerid can satisfy continuous monotonic increasing uniqueness. Shortcoming:worker1's ID ---------------------------------------------

long	get() return the id number.
long[]	getRangeId(int sizeOfIds) Get a segment of numbers at a time and return the minimum and maximum available numbers of a batch.

Method Detail

get

long get()

return the id number.

Returns:

long id number.

getRangeId

long[] getRangeId(int sizeOfIds)

Get a segment of numbers at a time and return the minimum and maximum available numbers of a batch.
eg: [100000,101000],array[0]=100000,array[1]=101000.
In some algorithms, such as:PearFlowerId,OneTimeSnowflakeId,
1) The parameter sizeOfIds should not be greater than 8192.
2) In order to make array[0]=min,array[1]=max in the range of series, it is possible to waste id number;
if you don't want to, you can loop call the get() method or use SerialUniqueId algorithm.
The SerialUniqueId algorithm does not have the above two problems.

Parameters:

sizeOfIds - the size Of ids in one batch.

Returns:

return the array of long. array[0]=min,array[1]=max.
