Example 1 with DoublePositionEvent

use of org.eclipse.sirius.components.diagrams.events.DoublePositionEvent in project sirius-components by eclipse-sirius.

the class IncrementalLayoutEngine method layoutEdge.

private void layoutEdge(Optional<IDiagramEvent> optionalDiagramElementEvent, EdgeLayoutData edge) {
    // @formatter:off
    optionalDiagramElementEvent.filter(DoublePositionEvent.class::isInstance).map(DoublePositionEvent.class::cast).ifPresent(doublePositionEvent -> {
        Ratio edgeSourceAnchorRelativePosition = this.getPositionProportionOfEdgeEndAbsolutePosition(edge.getSource(), doublePositionEvent.getSourcePosition());
        Ratio edgeTargetAnchorRelativePosition = this.getPositionProportionOfEdgeEndAbsolutePosition(edge.getTarget(), doublePositionEvent.getTargetPosition());
        edge.setSourceAnchorRelativePosition(edgeSourceAnchorRelativePosition);
        edge.setTargetAnchorRelativePosition(edgeTargetAnchorRelativePosition);
    });
    // @formatter:on
    // recompute the edge routing points
    edge.setRoutingPoints(this.edgeRoutingPointsProvider.getRoutingPoints(edge));
    // recompute edge labels
    if (edge.getCenterLabel() != null) {
        edge.getCenterLabel().setPosition(this.edgeLabelPositionProvider.getCenterPosition(edge, edge.getCenterLabel()));
    }
}
