Class GraphLayouts

java.lang.Object

it.univr.di.cstnu.gui.layout.GraphLayouts

public final class GraphLayouts
extends Object

Registry of the graph layouts available to the user interface.

The ordered list returned by available() is the canonical source of truth for the UI menu: it defines both which layouts exist and the order in which they are presented to the user. Layout classes must not be instantiated elsewhere in the UI; use this factory instead so that adding or removing a layout requires only a change here.
