Diff (The Adobe AEM Quickstart and Web Application. 6.6.0)

java.lang.Object
- org.apache.commons.lang3.tuple.Pair<T,T>
- - org.apache.commons.lang3.builder.Diff<T>

Type Parameters:

T - The type of object contained within this Diff. Differences between primitive objects are stored as their Object wrapper equivalent.

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<Pair<T,T>>, java.util.Map.Entry<T,T>
```
public abstract class Diff<T>
extends Pair<T,T>
```
A Diff contains the differences between two Diffable class fields.
Typically, Diffs are retrieved by using a DiffBuilder to produce a DiffResult, containing the differences between two objects.
