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.

Method Details
-
initialize
void initialize()Initializes fields in the node that may not have been set during the constructor. Must be called before the iterations begin. -
setInitializer
- Parameters:
initializer
- a function that specifies initial locations for all vertices
-
setGraph
- Parameters:
graph
- the graph that this algorithm is to operate on
-
getGraph
- Returns:
- the graph that this Layout refers to
-
reset
void reset() -
setSize
- Parameters:
d
- the space to use to lay out this graph
-
getSize
Dimension getSize()- Returns:
- the current size of the visualization's space
-
lock
Locks or unlocks the specified vertex. Locking the vertex fixes it at its current position, so that it will not be affected by the layout algorithm. Unlocking it allows the layout algorithm to change the vertex's position.- Parameters:
v
- the vertex to lock/unlockstate
-true
to lock the vertex,false
to unlock it
-
isLocked
- Parameters:
v
- the vertex whose locked state is being queried- Returns:
true
if the position of vertexv
is locked
-
setLocation
Changes the layout coordinates ofv
tolocation
.- Parameters:
v
- the vertex whose location is to be specifiedlocation
- the coordinates of the specified location
