BlossomVNode.IncidentEdgeIterator

java.lang.Object
- org.jgrapht.alg.matching.blossom.v5.BlossomVNode.IncidentEdgeIterator

All Implemented Interfaces:

java.util.Iterator<BlossomVEdge>

Enclosing class:

BlossomVNode
```
public class BlossomVNode.IncidentEdgeIterator
extends java.lang.Object
implements java.util.Iterator<BlossomVEdge>
```
An iterator for traversing the edges incident to this node.
This iterator has a feature that during every step it knows the next edge it'll return to the caller. That's why it is safe to modify the current edge (move it to another node, for example).

Field Summary

Fields
Modifier and Type	Field	Description
`private int`	`currentDir`	The direction of the current edge
`private int`	`nextDir`	Direction of the `nextEdge`
`private BlossomVEdge`	`nextEdge`	The edge that will be returned after the next call to `next()`.

- Field Detail
  - currentDir
```
private int currentDir
```
    The direction of the current edge
  - nextDir
```
private int nextDir
```
    Direction of the nextEdge
  - nextEdge
```
private BlossomVEdge nextEdge
```
    The edge that will be returned after the next call to next(). Is null if all incident edges of the current node have been traversed.
- Constructor Detail
  - IncidentEdgeIterator
```
public IncidentEdgeIterator()
```
    Constructs a new instance of the IncidentEdgeIterator.
- Method Detail
  - getDir
```
public int getDir()
```
    Returns the direction of the edge returned by this iterator
    
    Returns:
    
    the direction of the edge returned by this iterator
  - hasNext
```
public boolean hasNext()
```
    Specified by:
    
    hasNext in interface java.util.Iterator<BlossomVEdge>
  - next
```
public BlossomVEdge next()
```
    Specified by:
    
    next in interface java.util.Iterator<BlossomVEdge>
  - advance
```
private void advance()
```
    Advances this iterator to the next incident edge. If previous edge was the last one with direction 0, then the direction of this iterator changes. If previous edge was the last incident edge, then nextEdge becomes null.
