1 Introduction

To support different databases alternative BasicSeriesGenerators to handle database specific sequence are required.

2 Using BasicSeriesGenerators to Handle Sequences

The BasicSeriesGenerator is no longer instantiated by calling its constructor. Now an instance of type BasicSeriesGenerator is created by calling the method of the corresponding BasicSeriesGeneratorFactory.

import com.google.inject.Inject;
import com.intershop.beehive.core.capi.series.BasicSeriesGenerator;
import com.intershop.beehive.core.capi.series.BasicSeriesGeneratorFactory;

public class BasicSeriesGeneratorTest
{

    @Inject
    private BasicSeriesGeneratorFactory generatorFactory;
    
    private BasicSeriesGenerator obtainSeriesGenerator(String identifier)
    {
        BasicSeriesGenerator generator = null;
        
        // ...
        
        if (generator == null)
        {
            generator = generatorFactory.createGenerator(identifier);
        }
        
        return generator;
    }
    
}
