Interface Diagnostic<S>

Contents
  • 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.

    Since:
    1.6

    • Field Detail

      • NOPOS

        static final long NOPOS
        Used to signal that no position is available.

    • Method Detail

      • getKind

        Diagnostic.Kind getKind()
        Gets the kind of this diagnostic, for example, error or warning.
        Returns:
        the kind of this diagnostic

      • getSource

        S getSource()
        Gets the source object associated with this diagnostic.
        Returns:
        the source object associated with this diagnostic. null if no source object is associated with the diagnostic.

      • getPosition

        long getPosition()
        Gets a character offset from the beginning of the source object associated with this diagnostic that indicates the location of the problem. In addition, the following must be true:

        getStartPostion() <= getPosition()

        getPosition() <= getEndPosition()

        Returns:
        character offset from beginning of source; NOPOS if getSource() would return null or if no location is suitable

      • getStartPosition

        long getStartPosition()
        Gets the character offset from the beginning of the file associated with this diagnostic that indicates the start of the problem.
        Returns:
        offset from beginning of file; NOPOS if and only if getPosition() returns NOPOS

      • getEndPosition

        long getEndPosition()
        Gets the character offset from the beginning of the file associated with this diagnostic that indicates the end of the problem.
        Returns:
        offset from beginning of file; NOPOS if and only if getPosition() returns NOPOS

      • getLineNumber

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

      • getColumnNumber

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

      • getCode

        String getCode()
        Gets 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)
        Gets a localized message for the given locale. The actual message is implementation-dependent. If the locale is null use the default locale.
        Parameters:
        locale - a locale; might be null
