| <p>This module provides a collection of utilities for working with |
| pretty-printers. |
| </p> |
| <dl compact="compact"> |
| <dt><code>PrettyPrinter (<var>name</var>, <var>subprinters</var>=None)</code></dt> |
| <dd><p>This class specifies the API that makes ‘<samp>info pretty-printer</samp>’, |
| ‘<samp>enable pretty-printer</samp>’ and ‘<samp>disable pretty-printer</samp>’ work. |
| Pretty-printers should generally inherit from this class. |
| </p> |
| </dd> |
| <dt><code>SubPrettyPrinter (<var>name</var>)</code></dt> |
| <dd><p>For printers that handle multiple types, this class specifies the |
| corresponding API for the subprinters. |
| </p> |
| </dd> |
| <dt><code>RegexpCollectionPrettyPrinter (<var>name</var>)</code></dt> |
| <dd><p>Utility class for handling multiple printers, all recognized via |
| regular expressions. |
| See <a href="Writing-a-Pretty_002dPrinter.html#Writing-a-Pretty_002dPrinter">Writing a Pretty-Printer</a>, for an example. |
| </p> |
| </dd> |
| <dt><code>FlagEnumerationPrinter (<var>name</var>)</code></dt> |
| <dd><p>A pretty-printer which handles printing of <code>enum</code> values. Unlike |
| <small>GDB</small>’s built-in <code>enum</code> printing, this printer attempts to |
| work properly when there is some overlap between the enumeration |
| constants. The argument <var>name</var> is the name of the printer and |
| also the name of the <code>enum</code> type to look up. |
| </p> |
| </dd> |
| <dt><code>register_pretty_printer (<var>obj</var>, <var>printer</var>, <var>replace</var>=False)</code></dt> |
| <dd><p>Register <var>printer</var> with the pretty-printer list of <var>obj</var>. |
| If <var>replace</var> is <code>True</code> then any existing copy of the printer |
| is replaced. Otherwise a <code>RuntimeError</code> exception is raised |
| if a printer with the same name already exists. |
