Method Detail

shutdown

public void shutdown()

startClusterGroup

public void startClusterGroup()

Description copied from class: ClusterGenerator

Called at the start of clustering.

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

Overrides:

startClusterGroup in class ClusterGenerator

makeClusterGroup

public ClusterGroup makeClusterGroup(ClusterInfo clusterInfo)

Description copied from class: ClusterGenerator

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.

Overrides:

makeClusterGroup in class ClusterGenerator

Returns:

a cluster group for a given collection of markers.

endClusterGroup

public void endClusterGroup()

Description copied from class: ClusterGenerator

Called at the end of clustering.

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

Overrides:

endClusterGroup in class ClusterGenerator

clusterNumber

public int clusterNumber()

Description copied from class: ClusterGenerator

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

Overrides:

clusterNumber in class ClusterGenerator

Returns:

the cluster number we're covering

clusterLayoutSize

public Point2d clusterLayoutSize()

Description copied from class: ClusterGenerator

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.

Overrides:

clusterLayoutSize in class ClusterGenerator

Returns:

The size of the cluster that will be created.

selectable

public boolean selectable()

Description copied from class: ClusterGenerator

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

Overrides:

selectable in class ClusterGenerator

Returns:

markerAnimationTime

public double markerAnimationTime()

Description copied from class: ClusterGenerator

How long to animate markers the join and leave a cluster

Overrides:

markerAnimationTime in class ClusterGenerator

Returns:

time in seconds
