Method Details

exists

public static SubQuery exists(String path,
 Junction.Type junction)

existsNested

public static SubQuery existsNested(String path,
 Junction.Type junction)

If `path` involves multiple paths (like relFoo.relBar), create nested exists. Otherwise it is the same as exists(String). Example: instead of `exists(relFoo.relBar where …` do `exists(relFoo where exists(relBar where –))` A special SubQuery class is returned, where each condition that is added via `where` calls is appended to the innermost subquery. Calls to `isTrue` apply to all subqueries. All other (reading) operations are applied to the root subquery.
