The Checker Framework enhances Java's type system to make it more powerful and useful. This lets software developers detect and prevent errors in their Java programs. The Checker Framework includes compiler plug-ins ("checkers") that find bugs or verify their absence. It also permits you to write your own compiler plug-ins.

There is a newer version: 3.42.0-eisop4

/**
 * An annotation used to indicate what lint options a checker supports. For example, if a checker
 * class (one that extends BaseTypeChecker) is annotated with
 * {@code @SupportedLintOptions({"dotequals"})}, then the checker accepts the command-line option
 * {@code -Alint=-dotequals}.
 *
 * This annotation is optional and many checkers do not contain an {@code @SupportedLintOptions}
 * annotation.
 *
 * The {@link SourceChecker#getSupportedLintOptions} method can construct its result from the
 * value of this annotation.
