Usage

From source file:org.kuali.rice.krad.data.platform.MaxValueIncrementerFactory.java

/**
 * Checks the config file for any references to
 * {@code rice.krad.data.platform.incrementer.(DATASOURCE, ex mysql, oracle).(VERSION optional)}.
 *
 * <p>If matching one found attempts to instantiate it to return back to factory for use.</p>
 *
 * @param platformInfo the {@link DatabasePlatformInfo}.
 * @param dataSource the {@link DataSource} for which to retrieve the incrementer.
 * @param incrementerName the name of the incrementer.
 * @param columnName the name of the column to increment.
 * @return a config set customized incrementer that matches and can be used to generate the next incremented value
 *         for the given incrementer against the specified {@link DataSource}
 * @throws InstantiationError if cannot instantiate passed in class.
