Class Inheritance
All Implemented Interfaces

Imports
javax.sql.DataSource, org.springframework.beans.factory.InitializingBean, org.springframework.dao.DataAccessException, org.springframework.util.Assert
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.

Constructor Summary

AccessConstructor and Description
public
AbstractDataFieldMaxValueIncrementer()

Default constructor for bean property style usage.

Method Summary

Modifier and TypeMethod and Description
public void
afterPropertiesSet()

Implements org.springframework.beans.factory.InitializingBean.afterPropertiesSet.

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.

public DataSource
getDataSource()

Return the data source to retrieve the value from.

public String
getIncrementerName()

Return the name of the sequence/table.

protected abstract 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.
getNextKey()

Determine the next key to use, as a long.

public int
getPaddingLength()

Return the padding length for String values.

public int
nextIntValue()

Implements org.springframework.jdbc.support.incrementer.DataFieldMaxValueIncrementer.nextIntValue.

Increment the data store field's max value as int.
public long
nextLongValue()

Implements org.springframework.jdbc.support.incrementer.DataFieldMaxValueIncrementer.nextLongValue.

Increment the data store field's max value as long.
public String
nextStringValue()

Implements org.springframework.jdbc.support.incrementer.DataFieldMaxValueIncrementer.nextStringValue.

Increment the data store field's max value as String.
public void
setDataSource(DataSource dataSource)

Set the data source to retrieve the value from.

public void
setIncrementerName(String incrementerName)

Set the name of the sequence/table.

public void
setPaddingLength(int paddingLength)

Set the padding length, i.e. the length to which a string result should be pre-pended with zeroes.
