Package org.hibernate.engine.jdbc

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.

See Also:

Serialized Form

Implementation 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 sizes, by standard, are allowed a "multiplier", K (Kb), M (Mb) or G (Gb).
