Method Detail

calculateLayout

public void calculateLayout()

Description copied from class: LayoutEngine

calculate the changes required to move the graph to a nicer layout. This method does not actually update the position of the nodes, rather this should be done by the LayoutEngine.applyLayout() method. Potentially, this means that the caller can calculate new positions (stored in the NodeLayouts), then opt not to apply the changes if it does not lead to an improvement. In practice this has not yet been utilised and such decisions are usually made internally to the layout engine.

Overrides:

applyLayout

public boolean applyLayout()

Description copied from class: LayoutEngine

apply the changes calculated by LayoutEngine.calculateLayout()

Specified by:

applyLayout in class LayoutEngine

Returns:

true when a stable state is reached

getName
