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.

Since:

1.6

Nested Class Summary

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

Returns:

a localized message
