GEdgeWeightMetric

Type Parameters:

E - the type of the edge
```
public interface GEdgeWeightMetric<E extends GEdge<?>>
```
A callback to get the weight of an edge Analogous to Java's Comparator, this provides a means to override the weight of an edge in a graph, or provide a weight in the absence of a natural weight, when executing various graph algorithms, e.g., shortest path.

`double`	`computeWeight(E e)`	Compute or retrieve the weight of the given edge
`static <V,E extends GEdge<V>> GEdgeWeightMetric<E>`	`naturalMetric()`	Use the natural weight of each edge The metric assumes every edge is a `GWeightedEdge`.

```
static <V,E extends GEdge<V>> GEdgeWeightMetric<E> unitMetric()
```
    Measure every edge as having a weight of 1
    
    Returns:
    
    the metric
  - naturalMetric
```
static <V,E extends GEdge<V>> GEdgeWeightMetric<E> naturalMetric()
```
    Use the natural weight of each edge The metric assumes every edge is a GWeightedEdge. If not, you will likely encounter a ClassCastException.
    
    Returns:
    
    the metric
  - computeWeight
```
double computeWeight(E e)
```
    Compute or retrieve the weight of the given edge
    
    Parameters:
    
    e - the edge
    
    Returns:
    
    the weight
