Method Detail

getAtomics

public static Vector getAtomics(Vertex p)

advancePositions

public void advancePositions()

?

Specified by:

advancePositions in interface Layout

Specified by:

advancePositions in class AbstractLayout

See Also:

Layout.advancePositions()

applyFilter

public void applyFilter(Graph g)

Description copied from class: AbstractLayout

Applies the filter to the current graph. The default implementation merely makes fewer vertices available to the getVisibleVertices and getVisibleEdges methods.

Specified by:

applyFilter in interface Layout

Overrides:

applyFilter in class AbstractLayout

Parameters:

g - a filtered graph that is a subgraph of the Graph returned by getGraph

See Also:

Layout.applyFilter(Graph g)

getDepth

public int getDepth(Vertex v)

getRootVertex

public Vertex getRootVertex()

Returns:

Returns the rootVertex_.

incrementsAreDone

public boolean incrementsAreDone()

?

Specified by:

incrementsAreDone in interface Layout

See Also:

Layout.incrementsAreDone()

initialize

public void initialize(Dimension size)

Description copied from class: AbstractLayout

Initializer, calls intialize_local and initializeLocations to start construction process.

Specified by:

initialize in interface Layout

Overrides:

initialize in class AbstractLayout

initialize_local_vertex

protected void initialize_local_vertex(Vertex v)

?

Specified by:

initialize_local_vertex in class AbstractLayout

See Also:

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

initializeLocations

protected void initializeLocations()

Description copied from class: AbstractLayout

This method calls initialize_local_vertex for each vertex, and also adds initial coordinate information for each vertex. (The vertex's initial location is set by calling initializeLocation.

Overrides:

initializeLocations in class AbstractLayout

isIncremental

public boolean isIncremental()

?

Specified by:

isIncremental in interface Layout

See Also:

Layout.isIncremental()

setRootVertex

public void setRootVertex(Vertex rootVertex_)

Parameters:

rootVertex_ - The rootVertex_ to set.
