<h1 class="title">How This API Document Is Organized</h1>
<div class="sub-title">This API (Application Programming Interface) document has pages corresponding to the items in the navigation bar, described as follows.</div>
</div>
<section class="help-section">
<h2>Module</h2>
<p>Each module has a page that contains a list of its packages, dependencies on other modules, and services, with a summary for each. These pages may contain three categories:</p>
<ul class="help-section-list">
<li>Packages</li>
<li>Modules</li>
<li>Services</li>
</ul>
</section>
<section class="help-section">
<h2>Package</h2>
<p>Each package has a page that contains a list of its classes and interfaces, with a summary for each. These pages may contain six categories:</p>
<ul class="help-section-list">
<li>Interfaces</li>
<li>Classes</li>
<li>Enums</li>
<li>Exceptions</li>
<li>Errors</li>
<li>Annotation Types</li>
</ul>
</section>
<section class="help-section">
<h2>Class or Interface</h2>
<p>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:</p>
<ul class="help-section-list">
<li>Class Inheritance Diagram</li>
<li>Direct Subclasses</li>
<li>All Known Subinterfaces</li>
<li>All Known Implementing Classes</li>
<li>Class or Interface Declaration</li>
<li>Class or Interface Description</li>
</ul>
<br>
<ul class="help-section-list">
<li>Nested Class Summary</li>
<li>Field Summary</li>
<li>Property Summary</li>
<li>Constructor Summary</li>
<li>Method Summary</li>
</ul>
<br>
<ul class="help-section-list">
<li>Field Details</li>
<li>Property Details</li>
<li>Constructor Details</li>
<li>Method Details</li>
</ul>
<p>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.</p>
</section>
<section class="help-section">
<h2>Annotation Type</h2>
<p>Each annotation type has its own separate page with the following sections:</p>
<ul class="help-section-list">
<li>Annotation Type Declaration</li>
<li>Annotation Type Description</li>
<li>Required Element Summary</li>
<li>Optional Element Summary</li>
<li>Element Details</li>
</ul>
</section>
<section class="help-section">
<h2>Enum</h2>
<p>Each enum has its own separate page with the following sections:</p>
<ul class="help-section-list">
<li>Enum Declaration</li>
<li>Enum Description</li>
<li>Enum Constant Summary</li>
<li>Enum Constant Details</li>
</ul>
</section>
<section class="help-section">
<h2>Tree (Class Hierarchy)</h2>
<p>There is a <a href="overview-tree.html">Class Hierarchy</a> page for all packages, plus a hierarchy for each package. Each hierarchy page contains a list of classes and a list of interfaces. Classes are organized by inheritance structure starting with <code>java.lang.Object</code>. Interfaces do not inherit from <code>java.lang.Object</code>.</p>
<ul class="help-section-list">
<li>When viewing the Overview page, clicking on "Tree" displays the hierarchy for all packages.</li>
<li>When viewing a particular package, class or interface page, clicking on "Tree" displays the hierarchy for only that package.</li>
</ul>
</section>
<section class="help-section">
<h2>Deprecated API</h2>
<p>The <a href="deprecated-list.html">Deprecated API</a> page lists all of the API that have been deprecated. A deprecated API is not recommended for use, generally due to shortcomings, and a replacement API is usually given. Deprecated APIs may be removed in future implementations.</p>
</section>
<section class="help-section">
<h2>Index</h2>
<p>The <a href="index-all.html">Index</a> contains an alphabetic index of all classes, interfaces, constructors, methods, and fields, as well as lists of all packages and all classes.</p>
</section>
<section class="help-section">
<h2>Serialized Form</h2>
<p>Each serializable or externalizable class has a description of its serialization fields and methods. This information is of interest to those who implement rather than use 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.</p>
</section>
<section class="help-section">
<h2>Constant Field Values</h2>
<p>The <a href="constant-values.html">Constant Field Values</a> page lists the static final fields and their values.</p>
</section>
<section class="help-section">
<h2>Search</h2>
<p>You can search for definitions of modules, packages, types, fields, methods, system properties and other terms defined in the API, using some or all of the name, optionally using "camel-case" abbreviations. For example:</p>
<ul class="help-section-list">
<li><code>j.l.obj</code> will match "java.lang.Object"</li>
<li><code>InpStr</code> will match "java.io.InputStream"</li>
