java.lang.Object
- net.imglib2.transform.integer.permutation.AbstractPermutationTransform

All Implemented Interfaces:

InvertibleTransform, Transform

Direct Known Subclasses:

PermutationTransform, SingleDimensionPermutationTransform
```
public abstract class AbstractPermutationTransform
extends Object
implements InvertibleTransform
```
Bijective integer transform mapping between integer coordinates in [0,n-1]. Currently, this transform handles only coordinates in the integer range because it is implemented using primitive arrays with integer indices for efficiency reasons. Expect this permutation to be transferred to long coordinates some time in more distant future.
