Constructor Detail

FRLayout

public FRLayout(GraphView view)

Method Detail

doLayout

public void doLayout()

Specified by:

doLayout in class AbstractLayout

getStatus

public java.lang.String getStatus()

Returns the current temperature and number of iterations elapsed, as a string.

Overrides:

getStatus in class AbstractLayout

forceMove

public void forceMove(NodeView picked,
                      int x,
                      int y)

Allow a node to be forced into position

initialize_local

protected void initialize_local()

Description copied from class: AbstractLayout

Initializes all local information, and is called immediately within the initialize() process. The user is responsible for overriding this method to do any construction that may be necessary: for example, to initialize local per-edge or graph-wide data.

Specified by:

initialize_local in class AbstractLayout

initialize_local_node_view

protected void initialize_local_node_view(NodeView v)

Description copied from class: AbstractLayout

Initializes the local information on a single vertex. The user is responsible for overriding this method to do any vertex-level construction that may be necessary: for example, to attach vertex-level information to each vertex.

Specified by:

initialize_local_node_view in class AbstractLayout

advancePositions

public void advancePositions()

Moves the iteration forward one notch, calculation attraction and repulsion between nodes and edges and cooling the temperature.

Specified by:

advancePositions in class AbstractLayout

See Also:

Layout#advancePositions()

calcPositions

public void calcPositions(NodeView node_view)

This gets called for every NodeView.

calcAttraction

public void calcAttraction(EdgeView e)

Calculates the attractions for each edge this should have options to be weighted

calcRepulsion

public void calcRepulsion(NodeView nv1)

Finds the replusive forces for a node

setMaxIterations

public void setMaxIterations(int maxIterations)

getFRData

public FRLayout.FRVertexData getFRData(NodeView v)

getFRData

public FRLayout.FRVertexData getFRData(int v)

isIncremental

public boolean isIncremental()

This one is an incremental visualization.

incrementsAreDone

public boolean incrementsAreDone()

Returns true once the current iteration has passed the maximum count, MAX_ITERATIONS.
