com.j_spaces.jdbc.builder.range.Range

com.j_spaces.jdbc.builder.range.SegmentRange

All Implemented Interfaces:

ICustomQuery, Externalizable, Serializable

public class SegmentRange
extends Range

Defines a range of objects. The range is defined by two objects - _min and _max. And represents a range in the following way: (_min,_max) ==> _min < x < _max (null,_max) ==> x < _max (_min,null) ==> x > _min
