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

  - getKind
```
Diagnostic.Kind getKind()
```
    Returns the kind of this diagnostic, for example, error or warning.
    Returns:
    the kind of this diagnostic
  - getSource
```
S getSource()
```
    Returns 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()
```
    Returns 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()
```
    Returns 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()
```
    Returns 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()
```
    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
```
long getColumnNumber()
```
    Returns 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()
```
    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.
    Parameters:
    locale - a locale; might be null
    Returns:
    a localized message
