所有已实现的接口:
InitializingBean, DataFieldMaxValueIncrementer
直接已知子类:
AbstractColumnMaxValueIncrementer, AbstractSequenceMaxValueIncrementer
```
public abstract class AbstractDataFieldMaxValueIncrementer
extends Object
implements DataFieldMaxValueIncrementer, InitializingBean
```
Base implementation of DataFieldMaxValueIncrementer that delegates to a single getNextKey() template method that returns a long. Uses longs for String values, padding with zeroes if required.

    从接口复制的说明: InitializingBean
    Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, ApplicationContextAware etc.
    This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.
    指定者:
    afterPropertiesSet 在接口中 InitializingBean
  - nextIntValue
```
public int nextIntValue()
                 throws DataAccessException
```
    从接口复制的说明: DataFieldMaxValueIncrementer
    Increment the data store field's max value as int.
    指定者:
    nextIntValue 在接口中 DataFieldMaxValueIncrementer
    返回:
    int next data store value such as max + 1
    抛出:
    DataAccessException - in case of errors
  - nextLongValue
```
public long nextLongValue()
                   throws DataAccessException
```
    从接口复制的说明: DataFieldMaxValueIncrementer
    Increment the data store field's max value as long.
    指定者:
    nextLongValue 在接口中 DataFieldMaxValueIncrementer
    返回:
    int next data store value such as max + 1
    抛出:
    DataAccessException - in case of errors
  - nextStringValue
```
public String nextStringValue()
                       throws DataAccessException
```
    从接口复制的说明: DataFieldMaxValueIncrementer
    Increment the data store field's max value as String.
    指定者:
    nextStringValue 在接口中 DataFieldMaxValueIncrementer
    返回:
    next data store value such as max + 1
    抛出:
    DataAccessException - in case of errors
  - getNextKey
```
protected abstract long getNextKey()
```
    Determine the next key to use, as a long.
    返回:
    the key to use as a long. It will eventually be converted later in another format by the public concrete methods of this class.
