The search box on the top left narrows the list of classes to those that
match a string search to your typing, use this to home in quickly on the class,
trait or object you are trying to find.
The letters underneath the search box list all fields, methods and other
tokens found during the creation of the Scaladoc. E.g. if you want to find
where the .reverse method you are using is defined, click on R in the
list of letters there, and then find in page to locate the .reverse method and
the list of implementing classes/traits.
The small icons on the left of the list of classes denote object O, class C
and/or trait T. Two icons show that this class or trait has a companion as
well. Clicking on the O takes you directly to the companion object instead
of the class or trait.
The same (but larger) icons at the top of the right pane in the title indicate
the same information (i.e. you are looking at the class, trait or object). If
the icon has a “peel over” corner on it, clicking will flip you between the
class/trait and its companion.
Methods and values may have information folded away that can be accessed by
clicking on the triangle to the left of the definition.
In the title bar, at the very top, is a breadcrumb list of the parent packages
and each package is a link to the package object documentation which sometimes
holds an overview of the package or API as a whole.
You can use the Hide and Focus links next to the packages to ignore a package
you no longer want to see in searches, or to concentrate only on that package
By expanding linear supertypes triangle, you can see the linearized trait
definitions for the current class, trait or object.
Known subclasses lists all subclasses for this entity within the current
Type hierarchy shows a graphical view of this class related to its super
classes and traits, immediate sub-types, and important related entities. The
graphics themselves are links to the various entities.
The link in the Source section takes you to the online source for the class
assuming it is available (and it certainly is for the core libraries and for
many other libraries).
