Use Cases

redunderline

Assume that you have a module using e.g. Parsing API to parse the source files and wants to mark the errors in the editor to be shown as red underlined in the editor. Here is the pseudo code that achieves this: 
                Document doc = ...;
ArrayList<ErrorDescription> errors = new ArrayList<ErrorDescription>();
for (<all errors from the parser that have parsed the doc>) {
    errors.add(
        ErrorDescriptionFactory.createErrorDescription(
            Severity.ERROR,
            d.getMessage(Locale.getDefault()),
            doc,
            doc.createPosition(start),
            doc.createPosition(end)
        )
    );
}
HintsController.setErrors(doc, "myerrors", errors);

warningwithfix

Adding a warning with fixes: 
                static final class FixImpl implements Fix {
...
}
...
Document doc = ...;
List<Fix> fixes = Arrays.<Fix>asList(new FixImpl(...));
ArrayList<ErrorDescription> warnings = new ArrayList<ErrorDescription>();
for (<all places where the warning should be displayed>) {
    warnings.add(
        ErrorDescriptionFactory.createErrorDescription(
            Severity.WARNING,
            displayName,
            fixes,
            doc,
            doc.createPosition(start),
            doc.createPosition(end)
        )
    );
}
HintsController.setErrors(doc, "mywarnings", warnings);
