Class Overview

Abstract base class for DataFieldMaxValueIncrementer implementations that use a database sequence. Subclasses need to provide the database-specific SQL to use.

Inherited Fields

From class org.springframework.jdbc.support.incrementer.AbstractDataFieldMaxValueIncrementer

Public Constructors
	AbstractSequenceMaxValueIncrementer() Default constructor for bean property style usage.
	AbstractSequenceMaxValueIncrementer(DataSource dataSource, String incrementerName) Convenience constructor.

Protected Methods
long	getNextKey() Executes the SQL as specified by `getSequenceQuery()`.
abstract String	getSequenceQuery() Return the database-specific query to use for retrieving a sequence value.

Inherited Methods

From class org.springframework.jdbc.support.incrementer.AbstractDataFieldMaxValueIncrementer

void	afterPropertiesSet() Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).
DataSource	getDataSource() Return the data source to retrieve the value from.
String	getIncrementerName() Return the name of the sequence/table.
abstract long	getNextKey() Determine the next key to use, as a long.
int	getPaddingLength() Return the padding length for String values.
int	nextIntValue() Increment the data store field's max value as int.
long	nextLongValue() Increment the data store field's max value as long.
String	nextStringValue() Increment the data store field's max value as String.
void	setDataSource(DataSource dataSource) Set the data source to retrieve the value from.
void	setIncrementerName(String incrementerName) Set the name of the sequence/table.
void	setPaddingLength(int paddingLength) Set the padding length, i.e.

Public Constructors

public AbstractSequenceMaxValueIncrementer ()

Default constructor for bean property style usage.

public AbstractSequenceMaxValueIncrementer (DataSource dataSource, String incrementerName)

Convenience constructor.

Parameters

dataSource	the DataSource to use
incrementerName	the name of the sequence/table to use

Protected Methods

protected long getNextKey ()

Executes the SQL as specified by getSequenceQuery().

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.

Throws

DataAccessException

protected abstract String getSequenceQuery ()

Return the database-specific query to use for retrieving a sequence value.

The provided SQL is supposed to result in a single row with a single column that allows for extracting a long value.
