```
public AbstractIdentityColumnMaxValueIncrementer()
```
    Default constructor for bean property style usage.
    另请参阅:

```
public AbstractIdentityColumnMaxValueIncrementer(DataSource dataSource,
                                                 String incrementerName,
                                                 String columnName)
```
- 方法详细资料
  - setDeleteSpecificValues
```
public void setDeleteSpecificValues(boolean deleteSpecificValues)
```
    Specify whether to delete the entire range below the current maximum key value (false - the default), or the specifically generated values (true). The former mode will use a where range clause whereas the latter will use an in clause starting with the lowest value minus 1, just preserving the maximum value.
  - isDeleteSpecificValues
```
public boolean isDeleteSpecificValues()
```
    Return whether to delete the entire range below the current maximum key value (false - the default), or the specifically generated values (true).
  - getNextKey
```
protected long getNextKey()
                   throws DataAccessException
```
    从类复制的说明: AbstractDataFieldMaxValueIncrementer
    Determine the next key to use, as a long.
    指定者:
    getNextKey 在类中 AbstractDataFieldMaxValueIncrementer
    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.
    抛出:
    DataAccessException
  - getIncrementStatement
```
protected abstract String getIncrementStatement()
```
    Statement to use to increment the "sequence" value.
    返回:
    the SQL statement to use
  - getIdentityStatement
```
protected abstract String getIdentityStatement()
```
    Statement to use to obtain the current identity value.
    返回:
    the SQL statement to use
  - getDeleteStatement
```
protected String getDeleteStatement(long[] values)
```
    Statement to use to clean up "sequence" values.
    The default implementation either deletes the entire range below the current maximum value, or the specifically generated values (starting with the lowest minus 1, just preserving the maximum value) - according to the isDeleteSpecificValues() setting.
    参数:
    values - the currently generated key values (the number of values corresponds to AbstractColumnMaxValueIncrementer.getCacheSize())
    返回:
    the SQL statement to use
