ICompareInputChangeListener (Eclipse Platform API Specification)

```
public interface ICompareInputChangeListener
```
Listener that gets informed if one (or more) of the three sides of an ICompareInput object changes its value.
For example when accepting an incoming addition the (non-null) left side of an ICompareInput is copied to the right side (which was null). This triggers a call to compareInputChanged(org.eclipse.compare.structuremergeviewer.ICompareInput) of registered ICompareInputChangeListener.
Note however, that listener are not informed if the content of one of the sides changes.
Clients may implement this interface. It is also implemented by viewers that take an ICompareInput as input.
