Interface Diagnostic<S>

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.

    • getSource

      S getSource()
      Returns the source object associated with this diagnostic.

      long getLineNumber()
      Returns the line number of the character offset returned by getPosition().
      Returns:
      a line number or NOPOS if and only if getPosition() returns NOPOS

    • getColumnNumber

    • getCode

      String getCode()
      Returns a diagnostic code indicating the type of diagnostic. The code is implementation-dependent and might be null.
      Returns:
      a diagnostic code

    • getMessage

      String getMessage(Locale locale)
      Returns a localized message for the given locale. The actual message is implementation-dependent. If the locale is null use the default locale.
