Method Summary

Modifier and Type	Method and Description
String	getJsonString()
Number	getNumber()
int	getScale()
Temporal	getTemporal()
int	hashBucket(int buckets)
boolean	isNull() Below methods are extract from Scalar interface, include: isNull、setNull、getNumber、getTemporal、hashBucket、getJsonString Purpose: Because new version now is support return Entity, if clients haven't modified old use(eg, use Scalar special method) need to adapt it, so the solution is extract methods from Scalar to its parent interface Entity.
