public abstract class AbstractColumnMaxValueIncrementer
extends AbstractDataFieldMaxValueIncrementer

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 AbstractDataFieldMaxValueIncrementer.getNextKey() implementation..

Method Detail

setColumnName

public void setColumnName(java.lang.String columnName)
Set the name of the column in the sequence table.


getColumnName

public java.lang.String getColumnName()
Return the name of the column in the sequence table.


setCacheSize

public void setCacheSize(int cacheSize)
Set the number of buffered keys.


getCacheSize

public int getCacheSize()
Return the number of buffered keys.


afterPropertiesSet

public void afterPropertiesSet()
Description copied from interface: InitializingBean
Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).

This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

Specified by:
afterPropertiesSet in interface InitializingBean
Overrides:
afterPropertiesSet in class AbstractDataFieldMaxValueIncrementer
