TMAbstractNode

public TMAbstractNode(String id)

Method Detail

setVisible

public final void setVisible(boolean visible)

setVisible is not supported in Vizigator.

Overrides:

setVisible in class com.touchgraph.graphlayout.Node

removeMouseoverIcon

public void removeMouseoverIcon()

Workaround that avoids mouseover icon hanging around after hiding node.

textColourForBackground

public boolean hasPathTo(TMAbstractNode target,
                         Set visited)

getEdges

public Iterator getEdges()

Overrides:

getEdges in class com.touchgraph.graphlayout.Node

Returns:

An iterator on all the edges.

getVisibleEdges

public Iterator getVisibleEdges()

Returns:

An iterator on the edges that are currently visible.

getVisibleEdgesList

public List getVisibleEdgesList()

Returns:

A list of the edges that are currently visible.

setBackColor

public void setBackColor(Color bgColor)
