protected GraphParms(int[] index,
                     int[] edges)
```
    Constructs a graph topology information object.
    
    Parameters:
    
    index - node degrees.
    
    edges - graph edges.
- Method Detail
  - getIndexCount
```
public int getIndexCount()
```
    Returns the number of nodes.
    
    Returns:
    
    number of nodes.
  - getIndex
```
public int getIndex(int i)
```
    Returns the index of the node i.
    getIndex(0) returns the degree of the node 0, and getIndex(i)-getIndex(i-1) is the degree of the node i.
    
    Parameters:
    
    i - position of the node.
    
    Returns:
    
    the index.
  - getEdgeCount
```
public int getEdgeCount()
```
    Returns the number of edges.
    
    Returns:
    
    number of edges.
  - getEdge
```
public int getEdge(int i)
```
    Returns the edge i.
    The list of neighbors of node zero is stored in getEdge(j), for 0 ≤ j ≤ getIndex(0)-1 and the list of neighbors of node i, i > 0, is stored in getEdge(j), getIndex(i-1) ≤ j ≤ getIndex(i)-1.
    
    Parameters:
    
    i - index of the edge.
    
    Returns:
    
    the edge.
