```
public class SbChannelList
extends Inventor
```
List of channel to extract. Specify a list of channel to extract. For instance: {0, 1, 2} represent 3 first channels. SbChannelList is an ordered set. Channels are present only one time and are sorted by order.
Channels can be accessed with operator[]. Number of channel can be accessed with getNumChannel().
Note: Because it is an ordered set, for a given SoImageDataAdapter if channelList.getNumChannel() == image.getNumChannel(), this imply that channelList contains all the channels of image.

```
public SbChannelList(long nbChannel)
```
    Construct channelList corresponding to all channel from 0 to n-1: {0, 1, 2, ..., n-1}.
  - SbChannelList
```
public SbChannelList(long n,
                     int[] channels)
```
    SbChannelList(1, {0}) means extract only the 1st channel. SbChannelList(3, {0, 1, 2}) means extract the 3 first channels. For performances reasons, the given list must be an ordered set. Each element must appears only 1 time and must be in order. If it is not the case, an exception error will be thrown.
    example of invalid arguments: SbChannelList(3, {1, 1, 2}) SbChannelList(3, {3, 2, 1})
    
    Parameters:
    
    n - number of elements in channels array.
    
    channels - and ordered set of int listing channel indices.
