- Type Parameters:
S
- the type of source object used by this diagnostic
public interface Diagnostic<S>
Interface for diagnostics from tools. A diagnostic usually reports
a problem at a specific position in a source file. However, not
all diagnostics are associated with a position or a file.
A position is a zero-based character offset from the beginning of
a file. Negative values (except NOPOS
) are not valid
positions.
Line and column numbers begin at 1. Negative values (except
NOPOS
) and 0 are not valid line or column numbers.
