```
public Cycle(Collection<Node> nodes)
```
- Method Detail
  - isValid
```
public boolean isValid()
```
    Tests if the cycle is valid. A valid cycle satisfies two conditions:
    
    1. Each pair of adjacent nodes share an edge.
    2. The first and last nodes share an edge. 3. The only node repetition is the first and last nodes.
    
    Specified by:
    
    isValid in interface NodeSequence
    
    Overrides:
    
    isValid in class Walk
    
    Returns:
    
    True if valid, otherwise false.
  - buildEdges
```
protected List<Edge> buildEdges()
```
    Description copied from class: Walk
    
    Internal method for building the edge set of the walk. This method calculated the edges upon every call.
    
    Overrides:
    
    buildEdges in class Walk
    
    Returns:
    
    The list of edges for the walk, or null if the edge set could not be calculated due to an invalid walk.
