Method Detail

getStatus

public java.lang.String getStatus()

Description copied from class: AbstractLayout

Returns the current status of the sytem, or null if there is no particular status to report. Useful for reporting things like number of iterations passed, temperature, and so on.By default, an AbstractLayout returns null for its status.

Specified by:

getStatus in interface Layout

Overrides:

getStatus in class AbstractLayout

isIncremental

public boolean isIncremental()

This one is not incremental.

incrementsAreDone

public boolean incrementsAreDone()

Returns true;

getRadius

public double getRadius()

setRadius

public void setRadius(double radius)

orderVertices

public void orderVertices(Vertex[] vertices)

Specifies the order of vertices. The first element of the specified array will be positioned with angle 0 (on the X axis), and the second one will be positioned with angle 1/n, and the third one will be positioned with angle 2/n, and so on.

The default implemention shuffles elements randomly.

getKey

public java.lang.Object getKey()

Returns a visualization-specific key (that is, specific both to this instance and AbstractLayout) that can be used to access UserData related to the AbstractLayout.

getCircleData

public CircleLayout.CircleVertexData getCircleData(Vertex v)

advancePositions

public void advancePositions()

Do nothing.
