 | <h1 class="epydoc"> API Documentation </h1> | 
 |  | 
 | <p> This document contains the API (Application Programming Interface) | 
 | documentation for this project.  Documentation for the Python | 
 | objects defined by the project is divided into separate pages for each | 
 | package, module, and class.  The API documentation also includes two | 
 | pages containing information about the project as a whole: a trees | 
 | page, and an index page.  </p> | 
 |  | 
 | <h2> Object Documentation </h2> | 
 |  | 
 |   <p>Each <strong>Package Documentation</strong> page contains: </p> | 
 |   <ul> | 
 |     <li> A description of the package. </li> | 
 |     <li> A list of the modules and sub-packages contained by the | 
 |     package.  </li> | 
 |     <li> A summary of the classes defined by the package. </li> | 
 |     <li> A summary of the functions defined by the package. </li> | 
 |     <li> A summary of the variables defined by the package. </li> | 
 |     <li> A detailed description of each function defined by the | 
 |     package. </li> | 
 |     <li> A detailed description of each variable defined by the | 
 |     package. </li> | 
 |   </ul> | 
 |    | 
 |   <p>Each <strong>Module Documentation</strong> page contains:</p> | 
 |   <ul> | 
 |     <li> A description of the module. </li> | 
 |     <li> A summary of the classes defined by the module. </li> | 
 |     <li> A summary of the functions defined by the module. </li> | 
 |     <li> A summary of the variables defined by the module. </li> | 
 |     <li> A detailed description of each function defined by the | 
 |     module. </li> | 
 |     <li> A detailed description of each variable defined by the | 
 |     module. </li> | 
 |   </ul> | 
 |    | 
 |   <p>Each <strong>Class Documentation</strong> page contains: </p> | 
 |   <ul> | 
 |     <li> A class inheritance diagram. </li> | 
 |     <li> A list of known subclasses. </li> | 
 |     <li> A description of the class. </li> | 
 |     <li> A summary of the methods defined by the class. </li> | 
 |     <li> A summary of the instance variables defined by the class. </li> | 
 |     <li> A summary of the class (static) variables defined by the | 
 |     class. </li>  | 
 |     <li> A detailed description of each method defined by the | 
 |     class. </li> | 
 |     <li> A detailed description of each instance variable defined by the | 
 |     class. </li>  | 
 |     <li> A detailed description of each class (static) variable defined | 
 |     by the class. </li>  | 
 |   </ul> | 
 |  | 
 | <h2> Project Documentation </h2> | 
 |  | 
 |   <p> The <strong>Trees</strong> page contains the module and class hierarchies: </p> | 
 |   <ul> | 
 |     <li> The <em>module hierarchy</em> lists every package and module, with | 
 |     modules grouped into packages.  At the top level, and within each | 
 |     package, modules and sub-packages are listed alphabetically. </li> | 
 |     <li> The <em>class hierarchy</em> lists every class, grouped by base | 
 |     class.  If a class has more than one base class, then it will be | 
 |     listed under each base class.  At the top level, and under each base | 
 |     class, classes are listed alphabetically. </li> | 
 |   </ul> | 
 |    | 
 |   <p> The <strong>Index</strong> page contains indices of terms and | 
 |   identifiers: </p> | 
 |   <ul> | 
 |     <li> The <em>term index</em> lists every term indexed by any object's | 
 |     documentation.  For each term, the index provides links to each | 
 |     place where the term is indexed. </li> | 
 |     <li> The <em>identifier index</em> lists the (short) name of every package, | 
 |     module, class, method, function, variable, and parameter.  For each | 
 |     identifier, the index provides a short description, and a link to | 
 |     its documentation. </li> | 
 |   </ul> | 
 |  | 
 | <h2> The Table of Contents </h2> | 
 |  | 
 | <p> The table of contents occupies the two frames on the left side of | 
 | the window.  The upper-left frame displays the <em>project | 
 | contents</em>, and the lower-left frame displays the <em>module | 
 | contents</em>: </p> | 
 |  | 
 | <table class="help summary" border="1" cellspacing="0" cellpadding="3"> | 
 |   <tr style="height: 30%"> | 
 |     <td align="center" style="font-size: small"> | 
 |        Project<br />Contents<hr />...</td> | 
 |     <td align="center" style="font-size: small" rowspan="2" width="70%"> |

 |       Module<br />Contents<hr /> <br />...<br />  | 
 |     </td> | 
 |   </tr> | 
 | </table><br /> | 
 |  | 
 | <p> The <strong>project contents frame</strong> contains a list of all packages | 
 | and modules that are defined by the project.  Clicking on an entry | 
 | will display its contents in the module contents frame.  Clicking on a | 
 | special entry, labeled "Everything," will display the contents of | 
 | the entire project. </p> | 
 |  | 
 | <p> The <strong>module contents frame</strong> contains a list of every | 
 | submodule, class, type, exception, function, and variable defined by a | 
 | module or package.  Clicking on an entry will display its | 
 | documentation in the API documentation frame.  Clicking on the name of | 
 | the module, at the top of the frame, will display the documentation | 
 | for the module itself. </p> | 
 |  | 
 | <p> The "<strong>frames</strong>" and "<strong>no frames</strong>" buttons below the top | 
 | navigation bar can be used to control whether the table of contents is | 
 | displayed or not. </p> | 
 |  | 
 | <h2> The Navigation Bar </h2> | 
 |  | 
 | <p> A navigation bar is located at the top and bottom of every page. | 
 | It indicates what type of page you are currently viewing, and allows | 
 | you to go to related pages.  The following table describes the labels | 
 | on the navigation bar.  Note that not some labels (such as | 
 | [Parent]) are not displayed on all pages. </p> | 
 |  | 
 | <table class="summary" border="1" cellspacing="0" cellpadding="3" width="100%"> | 
 | <tr class="summary"> | 
 |   <th>Label</th> | 
 |   <th>Highlighted when...</th> |

 |       <td valign="top">viewing the help page</td> | 
 |       <td valign="top"> the help page </td></tr> | 
 | </table> | 
 |  | 
 | <p> The "<strong>show private</strong>" and "<strong>hide private</strong>" buttons below | 
 | the top navigation bar can be used to control whether documentation | 
 | for private objects is displayed.  Private objects are usually defined | 
 | as objects whose (short) names begin with a single underscore, but do | 
 | not end with an underscore.  For example, "<code>_x</code>", | 
 | "<code>__pprint</code>", and "<code>epydoc.epytext._tokenize</code>" | 
 | are private objects; but "<code>re.sub</code>", | 
 | "<code>__init__</code>", and "<code>type_</code>" are not.  However, | 
 | if a module defines the "<code>__all__</code>" variable, then its | 
 | contents are used to decide which objects are private. </p> | 
 |  | 
 | <p> A timestamp below the bottom navigation bar indicates when each | 
 | page was last updated. </p> |
