Annotation Interface OnlineDocumentation

@Target(TYPE)
@Retention(SOURCE)
public @interface OnlineDocumentation

Signals that a Refaster rule or group of Refaster rules comes with online documentation.

The provided value may be a full URL, or a URL pattern containing either or both of the "${topLevelClassName}" and "${nestedClassName}" placeholders.

By default it is assumed that the Refaster rule(s) are documented on the Error Prone Support website. Annotations on nested classes override the documentation URL associated with any enclosing class.

NESTED_CLASS_URL_PLACEHOLDER

static final String NESTED_CLASS_URL_PLACEHOLDER

The URL placeholder value that will be replaced with the name of the nested class in which the annotated Refaster rule is located, if applicable.

If the Refaster rule is not defined in a nested class then this placeholder will be replaced with the empty string. In case the Refaster rule is syntactically nested inside a deeper hierarchy of classes, then this placeholder will be replaced with concatenation of the names of all these classes (except the top-level class name), separated by dots.
