Class MarkerFeature

  • All Implemented Interfaces:

    Serializable

    public class MarkerFeature
extends PointBasedFeature

    A convenience class for displaying icons or images, such as markers, at a specific location on the map.

    Technically this is a Feature that uses a Point geometry for representation, and a visual Style configured to use an Icon.

    The class provides a default marker icon if no custom icon is provided.

        Creates a new marker feature located at the specified coordinates, displaying the specified custom icon.The coordinates must be in the same projection as the View.getProjection() and Source.getProjection().

        NOTE: Icon instances should be reused between features in order to optimize memory-usage in the client-side component / browser. Creating a new instance of an icon for each feature is considered bad practice.

        coordinates - the coordinates that locate the feature

        icon - the icon to display the feature

    • Method Detail

      • getIcon

        public Icon getIcon()

        The icon used to visually display the marker feature. By default, this is a default marker icon provided by the component.

        CAUTION: Be careful when modifying the returned icon. Icon instances can, and should always be, reused between multiple markers. Modifying an icon can also affect other marker features. Instead of modifying the icon, consider preparing a set of distinct icons, and then using setIcon(Icon).

        Returns:

        the current icon

      • setIcon

        public void setIcon​(Icon icon)

        NOTE: Icon instances should be reused between features in order to optimize memory-usage in the client-side component / browser. Creating a new instance of an icon for each feature is considered bad practice.

        icon - the new icon, not null
