```
public State(java.lang.String name)
```
    Construct a vertex. (The name should be unique!)
    
    Parameters:
    
    name - The name associated with this vertex.
- Method Detail
  - addNeighbor
```
public void addNeighbor(State neighbor)
```
    Add a neighbor to the adjacency list for this vertex.
    
    Parameters:
    
    neighbor - A vertex to add to the adjacency list.
  - getNeighbors
```
public java.util.ArrayList<State> getNeighbors()
```
    Return the adjacency list for this vertex.
    
    Returns:
    
    The list of adjacent vertices.
  - isVisited
```
public boolean isVisited()
```
    Check to see if the current vertex has been visited. This value is not set automatically -- it must be set by by calling setVisited. (This could be useful in conducting recursive graph traversals.)
    
    Returns:
    
    True if the vertex has been visited, false otherwise.
  - setVisited
```
public void setVisited(boolean visited)
```
    Set or un-set the visited flag for this vertex.
    
    Parameters:
    
    visited - New value for the visited flag.
  - getName
```
public java.lang.String getName()
```
    Return the name associated with this vertex.
    
    Returns:
    
    The name.
  - toString
```
public java.lang.String toString()
```
    Overrides:
    
    toString in class java.lang.Object
