Detailed Description

Groups IconMapObject instances into clusters depending on zoom and proximity.

Referenced from LocationWindow.

Register icons with addIconMapObject, then optionally customize cluster appearance in ClusterMapObjectControllerListener (onClusterCreated) and ClusterMapObjectListener (onClusterChanged).

addIconMapObject()

abstract boolean com.navigine.idl.java.ClusterMapObjectController.addIconMapObject ( IconMapObject iconMapObject )

abstract

Adds an icon map object to the cluster controller.

Parameters

iconMapObject

Icon to cluster IconMapObject. Must be added to the same LocationWindow via addIconMapObject.

Returns

true if the icon was added, false otherwise.

Java code snippet:

        boolean added1 = clusterMapObjectController.addIconMapObject(clusterIcon1);
        boolean added2 = clusterMapObjectController.addIconMapObject(clusterIcon2);
        System.out.println("Registered icons for clustering: " + added1 + ", " + added2);

Kotlin code snippet:

        val added1 = controller.addIconMapObject(clusterIcon1)
        val added2 = controller.addIconMapObject(clusterIcon2)
        println("Registered icons for clustering: $added1, $added2")

Kotlin code snippet:

        controller.clear()
        println("Cleared cluster controller")

getClusters()

abstract ArrayList< ClusterMapObject > com.navigine.idl.java.ClusterMapObjectController.getClusters ( )

abstract

Returns a snapshot of currently visible clusters.

Java code snippet:

        List<ClusterMapObject> clusters = clusterMapObjectController.getClusters();
        System.out.println("Visible clusters: " + clusters.size());

Kotlin code snippet:

        val clusters = controller.getClusters()
        println("Visible clusters: ${clusters.size}")

getRadius()

abstract float com.navigine.idl.java.ClusterMapObjectController.getRadius ( )

abstract

Returns cluster radius in density-independent pixels.

Java code snippet:

        float clusterRadius = clusterMapObjectController.getRadius();
        System.out.println("Cluster radius: " + clusterRadius);

Kotlin code snippet:

        val clusterRadius = controller.getRadius()
        println("Cluster radius: $clusterRadius")

isEnabled()

abstract boolean com.navigine.idl.java.ClusterMapObjectController.isEnabled ( )

abstract

Returns whether clustering is enabled.

Java code snippet:

        boolean clusteringEnabled = clusterMapObjectController.isEnabled();

        println("Clustering is enabled: $clusteringEnabled")

removeIconMapObject()

abstract boolean com.navigine.idl.java.ClusterMapObjectController.removeIconMapObject ( IconMapObject iconMapObject )

abstract

Removes an icon map object from the cluster controller.

Parameters

iconMapObject

Icon to remove.

Returns

true if the icon was removed, false otherwise.

Java code snippet:

            boolean removed = clusterMapObjectController.removeIconMapObject(clusterIcon1);
            System.out.println("Removed icon from cluster controller: " + removed);

Kotlin code snippet:

            val removed = controller.removeIconMapObject(it)
            println("Removed icon from cluster controller: $removed")

removeListener()
