Method Details

getOrSetParam

public Object getOrSetParam(boolean getParam,
int index,
Object setValue)

Sets or gets a Parameter Threadsafe for the Algorithm.

Parameters:

getParam - If true, parameter with index "index" is returned, if false, the parameter is set (stored).

index - Index of Parameter to set or get

setValue - Object to store, if getParam is false

Returns:

Desired Parameter object or Paramter that was just stored.

storeOrSetNodePosition

public void storeOrSetNodePosition(boolean setAllNodePositions,
int index,
Node n,
double x,
double y)

Stores a node position (from the layout thread) or sets the node position of a node to a stored position (from the FrameMain thread). For synchronizing only one method stores or sets coordinates.

Parameters:

setAllNodePositions - If true all Nodepositions are actually modified.

index - Index of node

n - Node which should be modified or node that corespondends to the given coordinates.

x - Node position (X) for storage.

y - Node position (Y) for storage.
