Method Detail

startClusterGroup

public void startClusterGroup()

Called at the start of clustering.

Called right before we start generating clusters. Do you setup here if need be.

makeClusterGroup

public ClusterGroup makeClusterGroup(ClusterInfo clusterInfo)

Generate a cluster group for a given collection of markers.

Generate an image and size to represent the number of marker/labels we're consolidating.

Parameters:

clusterInfo -

Returns:

a cluster group for a given collection of markers.

makeClusterGroupJNI

public long makeClusterGroupJNI(int num)

endClusterGroup

public void endClusterGroup()

Called at the end of clustering.

If you were doing optimization (for image reuse, say) clean it up here.

clusterNumber

public int clusterNumber()

The Cluster number is referenced by screen markers. We group all the markers that share a cluster number together.

Returns:

the cluster number we're covering

clusterLayoutSize

public Point2d clusterLayoutSize()

The size of the cluster that will be created.

This is the biggest cluster you're likely to create. We use it to figure overlaps between clusters.

Returns:

The size of the cluster that will be created.

selectable

public boolean selectable()

Set this if you want cluster to be user selectable. On by default.

Returns:

markerAnimationTime

public double markerAnimationTime()

How long to animate markers the join and leave a cluster

Returns:

time in seconds
