Constructor & Destructor Documentation

ISOMLayout0()

grammarscope.jung2.layout.ISOMLayout0< V, E >.ISOMLayout0

(

final Graph< V, E >

Parameters

g

graph

Member Function Documentation

adjust()

synchronized void grammarscope.jung2.layout.ISOMLayout0< V, E >.adjust ( )

private

adjustVertex()

synchronized void grammarscope.jung2.layout.ISOMLayout0< V, E >.adjustVertex ( final V  v, final Point2D  tempXYD  )

private

done()

boolean grammarscope.jung2.layout.ISOMLayout0< V, E >.done

(

)

Returns true if the vertex positions are no longer being updated. Currently ISOMLayout stops updating vertex positions after a certain number of iterations have taken place.

Returns

true if the vertex position updates have stopped, false otherwise

getISOMVertexData()

ISOMVertexData grammarscope.jung2.layout.ISOMLayout0< V, E >.getISOMVertexData ( final V  v )

protected

getStatus()

String grammarscope.jung2.layout.ISOMLayout0< V, E >.getStatus

(

)

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

Returns

status string

initialize()

void grammarscope.jung2.layout.ISOMLayout0< V, E >.initialize

(

)

isIncremental()

boolean grammarscope.jung2.layout.ISOMLayout0< V, E >.isIncremental

(

)

This one is an incremental visualization.

Returns

true is the layout algorithm is incremental, false otherwise

reset()

void grammarscope.jung2.layout.ISOMLayout0< V, E >.reset

(

)

Resets the layout iteration count to 0, which allows the layout algorithm to continue updating vertex positions.

step()

void grammarscope.jung2.layout.ISOMLayout0< V, E >.step

(

)

Advances the current positions of the graph elements.

updateParameters()

synchronized void grammarscope.jung2.layout.ISOMLayout0< V, E >.updateParameters ( )

private
