Method Detail

getIsomKey

public Object getIsomKey()

getStatus

public String getStatus()

Returns the current number of epochs and execution status, as a string.

Specified by:

getStatus in interface Layout

Overrides:

getStatus in class AbstractLayout

Returns:

the status, as a string

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.

Overrides:

initialize_local in class AbstractLayout

initialize_local_vertex

protected void initialize_local_vertex(Vertex v)

(non-Javadoc)

Specified by:

initialize_local_vertex in class AbstractLayout

See Also:

AbstractLayout.initialize_local_vertex(edu.uci.ics.jung.graph.Vertex)

advancePositions

public void advancePositions()

Advances the current positions of the graph elements.

Specified by:

advancePositions in interface Layout

Specified by:

advancePositions in class AbstractLayout

See Also:

Layout.advancePositions()

getISOMVertexData

public ISOMLayout.ISOMVertexData getISOMVertexData(Vertex v)

isIncremental

public boolean isIncremental()

This one is an incremental visualization.

Returns:

true is the layout algorithm is incremental, false otherwise

incrementsAreDone

public boolean incrementsAreDone()

For now, we pretend it never finishes.

Returns:

true is the increments are done, false otherwise
