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
