public interface Diagnostic
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.Line terminator is as defined in ECMAScript specification which is one of { \u000A, \u000B, \u2028, \u2029 }.
