Style provider

The StyleProvider interface provides a way to customize the appearance of the single-area diagram.

Currently, there are 2 implementations of the StyleProvider: the BasicStyleProvider, the NominalVoltageStyleProvider and the TopologicalStyleProvider

Common features

The common features are factorized in the abstract classes AbstractStyleProvider and AbstractVoltageStyleProvider.

TopologicalStyleProvider feature

The bus nodes of a voltage level are each marked with a class depending on the nominal voltage and on their bus index. This leads to a colour shading for each range of nominal voltages defined by the BaseVoltagesConfig.

The TopologicalStyleProvider also supports highlighting of electrical buses on hover. In order to enable this feature, you can customize your SldParameters by using the BusHighlightStyleProviderFactory:

SldParameters sldParameters = new SldParameters().setStyleProviderFactory(new BusHighlightStyleProviderFactory());

If you don’t want to use the provided BusHighlightStyleProviderFactory in your SldParameters, you could also create your own StyleProviderFactory and include the TopologicalStyleProvider with the busHighlightOnHover parameter set to true in the StyleProvidersList:

public class YourCustomStyleProviderFactory implements StyleProviderFactory {
    @Override
    public StyleProvider create(Network network, SvgParameters svgParameters) {
        return new StyleProvidersList(new TopologicalStyleProvider(network, svgParameters, true), ...);
    }
}
