An abstract class that extends the guice
AbstractModule
The Barracuda Order Adapter is able to load an external guice module.
Only modules with the annotation
BarracudaOverridesModule will
be loaded. Such a class only needs to be on the classpath, and will
be picked up by scanning annotations via reflection.
example:
@BarracudaOverride
public class ExampleBarracudaOverridesModule extends BarracudaOverridesModule
{
...
}
Only certain classes may be overwritten. The interface methods
on this class define which classes are overridable.
If you plan on provide an override, then the implementation method should
have the annotation @Provides. Please also consider
the annotation @Singleton.
example:
@Provides
@Singleton
@Nullable
@Override
public DataSource getDataSource()
{
return DataSourceFactory.createDataSource(args);
}
If you do not plan on providing an implementation as defined by the
interface method. Then simply return null, and make sure to not add
the @Provides annotation.
example:
@Nullable
@Override
public PrecisionManager getPrecisionManager()
{
return null;
}
