abstract public class: AbstractColumnMaxValueIncrementer [javadoc | source]

java.lang.Object
   org.springframework.jdbc.support.incrementer.AbstractDataFieldMaxValueIncrementer
      org.springframework.jdbc.support.incrementer.AbstractColumnMaxValueIncrementer

All Implemented Interfaces:
DataFieldMaxValueIncrementer, InitializingBean

Direct Known Subclasses:
DerbyMaxValueIncrementer, MySQLMaxValueIncrementer, HsqlMaxValueIncrementer

Abstract base class for DataFieldMaxValueIncrementer implementations that use a column in a custom sequence table. Subclasses need to provide the specific handling of that table in their #getNextKey() implementation..
