Abstract Value Members

  1. abstract def abort(pos: blackbox.Context.Position, msg: String): Nothing

    Abruptly terminates current macro expansion leaving a note about what happened.

    Abruptly terminates current macro expansion leaving a note about what happened. Use enclosingPosition if you're in doubt what position to pass to pos.

  2. abstract def echo(pos: blackbox.Context.Position, msg: String): Unit

    For sending a message which should not be labelled as a warning/error, but also shouldn't require -verbose to be visible.

    For sending a message which should not be labelled as a warning/error, but also shouldn't require -verbose to be visible. Use enclosingPosition if you're in doubt what position to pass to pos.

  3. abstract def error(pos: blackbox.Context.Position, msg: String): Unit

    Emits a compilation error.

    Emits a compilation error. Use enclosingPosition if you're in doubt what position to pass to pos.

  4. abstract def hasErrors: Boolean

    Does the compilation session have any errors?

  5. abstract def hasWarnings: Boolean

    Does the compilation session have any warnings?

  6. abstract def info(pos: blackbox.Context.Position, msg: String, force: Boolean): Unit

    Emits an informational message, suppressed unless -verbose or force=true.

    Emits an informational message, suppressed unless -verbose or force=true. Use enclosingPosition if you're in doubt what position to pass to pos.

  7. abstract def warning(pos: blackbox.Context.Position, msg: String): Unit

    Emits a warning.
