## 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..

    - #### 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`
