EdgeIter (JGAlgo - Core 0.1.1.2 API)

All Superinterfaces:

it.unimi.dsi.fastutil.ints.IntIterator, Iterator<Integer>, PrimitiveIterator<Integer,IntConsumer>, PrimitiveIterator.OfInt
```
public interface EdgeIter
extends it.unimi.dsi.fastutil.ints.IntIterator
```
Iterator used to iterate over edges of a vertex.
Each int returned by IntIterator.nextInt() is an ID of an edge iterated by the iterator. The source and target of the last iterated edge are available by source() and target().
```
 
 Graph g = ...;
 int vertex = ...;
 for (EdgeIter eit = g.outEdges(vertex).iterator(); eit.hasNext();) {
 	int e = eit.nextInt();
 	int u = eit.source();
 	int v = eit.target();
 	assert vertex == u;
 	System.out.println("Out edge of " + vertex + ": " + e + "(" + u + ", " + v + ")");
 }
 
```

- Method Detail
  - source
```
int source()
```
    Get the source vertex of the last returned edge.
    The behavior is undefined if IntIterator.nextInt() was not called yet.
    
    Returns:
    
    the source vertex of the last returned edge
  - target
```
int target()
```
    Get the target vertex of the last returned edge.
    The behavior is undefined if IntIterator.nextInt() was not called yet.
    
    Returns:
    
    the target vertex of the last returned edge
