Example 1 with AboutToRemoveEdgesEvent

use of org.cytoscape.model.events.AboutToRemoveEdgesEvent in project cytoscape-impl by cytoscape.

the class CySubNetworkImpl method removeEdges.

@Override
public boolean removeEdges(final Collection<CyEdge> edges) {
    if (edges == null || edges.isEmpty())
        return false;
    // Possible error if one of the edges isn't contained in subnetwork, but
    // since this is only a notification, maybe that's OK.
    eventHelper.fireEvent(new AboutToRemoveEdgesEvent(this, edges));
    CyTable hiddenTable = getTable(CyEdge.class, CyNetwork.HIDDEN_ATTRS);
    CyTable localTable = getTable(CyEdge.class, CyNetwork.LOCAL_ATTRS);
    CyTable defaultTable = getTable(CyEdge.class, CyNetwork.DEFAULT_ATTRS);
    List<Long> suids = new ArrayList<>();
    for (CyEdge edge : edges) {
        if (containsEdge(edge)) {
            // getRow(edge).set(CyNetwork.SELECTED, false);
            suids.add(edge.getSUID());
        }
    }
    boolean ret = removeEdgesInternal(edges);
