Class Size

java.lang.Object

org.hibernate.engine.jdbc.Size

All Implemented Interfaces:

Serializable

public class Size
extends Object
implements Serializable

Models size restrictions/requirements on a column's datatype.

IMPL NOTE: since we do not necessarily know the datatype up front, and therefore do not necessarily know whether length or precision/scale sizing is needed, we simply account for both here. Additionally LOB definitions, by standard, are allowed a "multiplier" consisting of 'K' (Kb), 'M' (Mb) or 'G' (Gb).
