Class AbstractColumnMaxValueIncrementer

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

All Implemented Interfaces:
  InitializingBean, DataFieldMaxValueIncrementer

Direct Known Subclasses:
  DerbyMaxValueIncrementer, HsqlMaxValueIncrementer, MySQLMaxValueIncrementer, SqlServerMaxValueIncrementer, SybaseMaxValueIncrementer

    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..

  2.5.3

Constructor Detail

### AbstractColumnMaxValueIncrementer

    public AbstractColumnMaxValueIncrementer()

  Default constructor for bean property style usage.

  See Also:
    `AbstractDataFieldMaxValueIncrementer.setDataSource(javax.sql.DataSource)`, `AbstractDataFieldMaxValueIncrementer.setIncrementerName(java.lang.String)`, `setColumnName(java.lang.String)`

### AbstractColumnMaxValueIncrementer

    public AbstractColumnMaxValueIncrementer(DataSource dataSource,
                                             String incrementerName,
                                             String columnName)

  Convenience constructor.

  Parameters:
    `dataSource` - the DataSource to use
    `incrementerName` - the name of the sequence/table to use
    `columnName` - the name of the column in the sequence table to use

Method Detail

### setColumnName

    public void setColumnName(String columnName)

  Set the name of the column in the sequence table.

### getColumnName

    public 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`
