Method Detail

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.

incrementerColumnName - the primary key column name to set

getIncrementer

public 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

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
