Abstract3DLayout(GraphView view)
|
Method Summary | |
abstract void |
advancePositions()
Implementors must override this method in order to create a Layout. |
abstract void |
doLayout()
|
boolean |
dontMove(NodeView nv)
|
void |
forceMove(NodeView picked,
double x,
double y,
double z)
Forcibly moves a vertex to the (x,y) location by setting its x and y locations to the inputted location. |
java.awt.Dimension |
getCurrentSize()
Returns the current size of the visualization space, accoring to the last call to resize(). |
NodeView |
getNodeView(double x,
double y,
double z)
|
java.lang.String |
getStatus()
{@inheritDoc} By default, an AbstractLayout returns null for its status. |
protected abstract void |
initialize_local_node_view(NodeView nv)
Initializes the local information on a single vertex. |
protected abstract void |
initialize_local()
Initializes all local information, and is called immediately within the initialize() process. |
void |
initialize(java.awt.Dimension size)
Initializer, calls intialize_local and initializeLocations to start construction process. |
protected void |
initializeLocation(NodeView v,
java.awt.Dimension d)
Sets random locations for a vertex within the dimensions of the space. |
protected void |
initializeLocations()
This method calls initialize_local_vertex for each vertex, and also adds initial coordinate information for each vertex. |
void |
lockVertex(NodeView v)
Adds the vertex to the DontMove list |
void |
resize(java.awt.Dimension size)
When a visualizetion is resized, it presumably wants to fix the locations of the vertices and possibly to reinitialize its data. |
void |
restart()
Restarts the visualization entirely, as if the the user had pressed the "scramble" button. |
void |
unlockVertex(NodeView v)
Removes the vertex from the DontMove list |

public abstract void advancePositions()
Note that "locked" vertices are not to be moved; however, it is the policy of the visualization to decide how to handle them, and what to do with the vertices around them. Prototypical code might include a clipping like
for (Iterator i = getVertices().iterator(); i.hasNext() ) { Vertex v = (Vertex) i.next(); if (! dontmove.contains( v ) ) { ... // handle the node } else { // ignore the node } }
