Layout

All Superinterfaces:

org.apache.commons.collections4.Transformer<V,java.awt.geom.Point2D>

All Known Implementing Classes:

AbstractLayout, AggregateLayout, BalloonLayout, CircleLayout, DAGLayout, FRLayout, FRLayout2, ISOMLayout, KKLayout, LayoutDecorator, RadialTreeLayout, SpringLayout, SpringLayout2, StaticLayout, TreeLayout
```
public interface Layout<V,E>
extends org.apache.commons.collections4.Transformer<V,java.awt.geom.Point2D>
```
A generalized interface is a mechanism for returning (x,y) coordinates from vertices. In general, most of these methods are used to both control and get information from the layout algorithm.

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`edu.uci.ics.jung.graph.Graph<V,E>`	`getGraph()`	Returns the full graph (the one that was passed in at construction time) that this Layout refers to.
`java.awt.Dimension`	`getSize()`	Returns the current size of the visualization's space.
`void`	`initialize()`	Initializes fields in the node that may not have been set during the constructor.
`boolean`	`isLocked(V v)`	Returns `true` if the position of vertex `v` is locked.
`void`	`lock(V v, boolean state)`	Sets a flag which fixes this vertex in place.
`void`	`reset()`

    Parameters:
    
    v - vertex
  - isLocked
```
boolean isLocked(V v)
```
    Returns true if the position of vertex v is locked.
