Class NativeSequence
java.lang.Object
oracle.toplink.sequencing.Sequence
oracle.toplink.sequencing.StandardSequence
oracle.toplink.sequencing.QuerySequence
oracle.toplink.sequencing.NativeSequence
- All Implemented Interfaces:
- java.io.Serializable, java.lang.Cloneable
public class NativeSequence
- extends QuerySequence
Purpose: Define a database's native sequencing mechanism.
Description
Many databases have built in support for sequencing.
This can be a SEQUENCE object such as in Oracle,
or a auto-incrementing column such as the IDENTITY field in Sybase.
For an auto-incrementing column the preallocation size is always 1.
For a SEQUENCE object the preallocation size must match the SEQUENCE objects "increment by".
