All Implemented Interfaces:
InitializingBean, DataFieldMaxValueIncrementer
Direct Known Subclasses:
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.

    Description copied from interface: 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.
    Specified by:
    afterPropertiesSet in interface InitializingBean
  - nextIntValue
```
public int nextIntValue()
                 throws DataAccessException
```
    Description copied from interface: DataFieldMaxValueIncrementer
    Increment the data store field's max value as int.
    Specified by:
    nextIntValue in interface DataFieldMaxValueIncrementer
    Returns:
    int next data store value such as max + 1
    Throws:
    DataAccessException - in case of errors
  - nextLongValue
```
public long nextLongValue()
                   throws DataAccessException
```
    Description copied from interface: DataFieldMaxValueIncrementer
    Increment the data store field's max value as long.
    Specified by:
    nextLongValue in interface DataFieldMaxValueIncrementer
    Returns:
    int next data store value such as max + 1
    Throws:
    DataAccessException - in case of errors
  - nextStringValue
```
public String nextStringValue()
                       throws DataAccessException
```
    Description copied from interface: DataFieldMaxValueIncrementer
    Increment the data store field's max value as String.
    Specified by:
    nextStringValue in interface DataFieldMaxValueIncrementer
    Returns:
    next data store value such as max + 1
    Throws:
    DataAccessException - in case of errors
  - getNextKey
```
protected abstract long getNextKey()
```
    Determine the next key to use, as a long.
    Returns:
    the key to use as a long. It will eventually be converted later in another format by the public concrete methods of this class.
