ConnectedComponentsAlgo.Result (JGAlgo - Parent 0.2.0 API)

Enclosing interface:

ConnectedComponentsAlgo
```
public static interface ConnectedComponentsAlgo.Result
```
Result object for connectivity components calculation.
The result object contains the partition of the vertices into the connectivity components (strongly for directed graph). Each connectivity component (CC) is assigned a unique integer number in range [0, ccNum), and each vertex can be queried for its CC using getVertexCc(int).

- Method Detail
  - getVertexCc
```
int getVertexCc(int vertex)
```
    Get the connectivity component containing a vertex.
    
    Parameters:
    
    vertex - a vertex in the graph
    
    Returns:
    
    index of the connectivity component containing the vertex, in range [0, ccNum)
  - getNumberOfCcs
```
int getNumberOfCcs()
```
    Get the number of connectivity components in the graph.
    
    Returns:
    
    the number of connectivity components in the graph, non negative number
  - getCcVertices
```
IntCollection getCcVertices(int ccIdx)
```
    Get all the vertices that are part of a connectivity component.
    
    Parameters:
    
    ccIdx - index of a connectivity component
    
    Returns:
    
    the vertices that are part of the connectivity components
    
    Throws:
    
    IndexOutOfBoundsException - if ccIdx is negative or greater than the number of connectivity components
  - getCcEdges
```
IntCollection getCcEdges(int ccIdx)
```
    Get all the edges that are part of a connectivity component.
    An edge \((u,v)\) is part of a connectivity component if both \(u\) and \(v\) are part of the connectivity component.
    
    Parameters:
    
    ccIdx - index of a connectivity component
    
    Returns:
    
    the edges that are part of the connectivity components
    
    Throws:
    
    IndexOutOfBoundsException - if ccIdx is negative or greater than the number of connectivity components
