DefaultDataFieldMaxValueIncrementerFactory

public DefaultDataFieldMaxValueIncrementerFactory(DataSource dataSource)

Method Details

setIncrementerColumnName

public void setIncrementerColumnName(String incrementerColumnName)

Public setter for the column name (defaults to "ID") in the incrementer. Only used by some platforms (Derby, HSQL, MySQL, SQL Server and Sybase), and should be fine for use with Spring Batch meta data as long as the default batch schema hasn't been changed.

Parameters:

incrementerColumnName - the primary key column name to set

getIncrementer

public org.springframework.jdbc.support.incrementer.DataFieldMaxValueIncrementer getIncrementer(String incrementerType,
 String incrementerName)

Description copied from interface: DataFieldMaxValueIncrementerFactory

Return the DataFieldMaxValueIncrementer for the provided database type.

Specified by:

getIncrementer in interface DataFieldMaxValueIncrementerFactory

Parameters:

incrementerType - string represented database type

incrementerName - incrementer name to create. In many cases this may be the sequence name

Returns:

incrementer

isSupportedIncrementerType

public boolean isSupportedIncrementerType(String incrementerType)

Description copied from interface: DataFieldMaxValueIncrementerFactory

Returns boolean indicated whether or not the provided string is supported by this factory.

Specified by:

isSupportedIncrementerType in interface DataFieldMaxValueIncrementerFactory

Parameters:

incrementerType - String containing the database type.

Returns:

true if the incrementerType is supported by this database type. Else false is returned.

getSupportedIncrementerTypes

public String[] getSupportedIncrementerTypes()

Description copied from interface: DataFieldMaxValueIncrementerFactory

Returns the list of supported database incrementer types

Specified by:

getSupportedIncrementerTypes in interface DataFieldMaxValueIncrementerFactory

Returns:

an array of Strings containing the supported incrementer types.
