Method Detail

setSize

public void setSize(java.awt.Dimension size)

Description copied from class: TreeLayout

This method is not supported by this class. The size of the layout is determined by the topology of the tree, and by the horizontal and vertical spacing (optionally set by the constructor).

Specified by:

setSize in interface Layout<V,E>

Overrides:

setSize in class TreeLayout<V,E>

Parameters:

size - the space to use to lay out this graph

setLocation

public void setLocation(V v,
                        java.awt.geom.Point2D location)

Description copied from interface: Layout

Changes the layout coordinates of v to location.

Specified by:

setLocation in interface Layout<V,E>

Overrides:

setLocation in class TreeLayout<V,E>

Parameters:

v - the vertex whose location is to be specified

location - the coordinates of the specified location

getPolarLocations

public java.util.Map<V,PolarPoint> getPolarLocations()

Returns:

a map from vertices to their locations in polar coordinates.

apply

public java.awt.geom.Point2D apply(V v)

Specified by:

apply in interface com.google.common.base.Function<V,java.awt.geom.Point2D>

Overrides:

apply in class TreeLayout<V,E>
