Interface IDiffProvider

All Superinterfaces:

IProvider

public interface IDiffProvider
extends IProvider

A IDiffProvider provides character based diff services to other components.

A character based diff provides a hint at how the differences between two given text fragments may have occurred. There is no guarantee that the returned IDiffResults correspond to the real modifications made.

The actual diff algorithm used is not specified and it is up to the implementation how diffs are generated.

The most prominent user of this provider is the CPC Reconciler module.
