How This API Document Is Organized
This API (Application Programming Interface) document has pages corresponding to the items in the navigation bar, described as follows.
Overview
The Overview page is the front page of this API document and provides a list of all packages with a summary for each. This page can also contain an overall description of the set of packages.
Package
Each package has a page that contains a list of its classes and interfaces, with a summary for each. This page can contain six categories:
Interfaces (italic)
Classes
Enums
Exceptions
Errors
Annotation Types
Class/Interface
Each class, interface, nested class and nested interface has its own separate page. Each of these pages has three sections consisting of a class/interface description, summary tables, and detailed member descriptions:
Class inheritance diagram
Direct Subclasses
All Known Subinterfaces
All Known Implementing Classes
Class/interface declaration
Class/interface description
Nested Class Summary
Field Summary
Constructor Summary
Method Summary
Field Detail
Constructor Detail
Method Detail
Each summary entry contains the first sentence from the detailed description for that item. The summary entries are alphabetical, while the detailed descriptions are in the order they appear in the source code. This preserves the logical groupings established by the programmer.
Annotation Type
Each annotation type has its own separate page with the following sections:
Annotation Type declaration
Annotation Type description
Required Element Summary
Optional Element Summary
Element Detail
Enum
Each enum has its own separate page with the following sections:
Enum declaration
Enum description
Enum Constant Summary
Enum Constant Detail
Tree (Class Hierarchy)
There is a Class Hierarchy page for all packages, plus a hierarchy for each package. Each hierarchy page contains a list of classes and a list of interfaces. The classes are organized by inheritance structure starting with java.lang.Object. The interfaces do not inherit from java.lang.Object.
When viewing the Overview page, clicking on "Tree" displays the hierarchy for all packages.
When viewing a particular package, class or interface page, clicking "Tree" displays the hierarchy for only that package.
Deprecated API
The Deprecated API page lists all of the API that have been deprecated. A deprecated API is not recommended for use, generally due to improvements, and a replacement API is usually given. Deprecated APIs may be removed in future implementations.
Index
The Index contains an alphabetic list of all classes, interfaces, constructors, methods, and fields.
Prev/Next
These links take you to the next or previous class, interface, package, or related page.
Frames/No Frames
These links show and hide the HTML frames. All pages are available with or without frames.
Serialized Form
Each serializable or externalizable class has a description of its serialization fields and methods. This information is of interest to re-implementors, not to developers using the API. While there is no link in the navigation bar, you can get to this information by going to any serialized class and clicking "Serialized Form" in the "See also" section of the class description.
