 <h5 class="subsubsection">15.4.4.1 Method Names in Commands</h5>

 <p>The following commands have been extended to accept Objective-C method
 names as line specifications:

    <p><a name="index-clear_0040r_007b_002c-and-Objective_002dC_007d-1020"></a><a name="index-break_0040r_007b_002c-and-Objective_002dC_007d-1021"></a><a name="index-info-line_0040r_007b_002c-and-Objective_002dC_007d-1022"></a><a name="index-jump_0040r_007b_002c-and-Objective_002dC_007d-1023"></a><a name="index-list_0040r_007b_002c-and-Objective_002dC_007d-1024"></a>
      <ul>
 <li><code>clear</code>
 <li><code>break</code>
 <li><code>info line</code>
 <li><code>jump</code>
 <li><code>list</code>
 </ul>

    <p>A fully qualified Objective-C method name is specified as

 <pre class="smallexample">     -[<var>Class</var> <var>methodName</var>]
 </pre>
    <p>where the minus sign is used to indicate an instance method and a
 plus sign (not shown) is used to indicate a class method.  The class
 name <var>Class</var> and method name <var>methodName</var> are enclosed in
 brackets, similar to the way messages are specified in Objective-C
 source code.  For example, to set a breakpoint at the <code>create</code>
 instance method of class <code>Fruit</code> in the program currently being
 debugged, enter:

 <pre class="smallexample">     break -[Fruit create]
 </pre>
    <p>To list ten program lines around the <code>initialize</code> class method,
 enter:

 <pre class="smallexample">     list +[NSText initialize]
 </pre>
    <p>In the current version of <span class="sc">gdb</span>, the plus or minus sign is
 required.  In future versions of <span class="sc">gdb</span>, the plus or minus
 sign will be optional, but you can use it to narrow the search.  It
 is also possible to specify just a method name:

 <pre class="smallexample">     break create
 </pre>
    <p>You must specify the complete method name, including any colons.  If
 your program's source files contain more than one <code>create</code> method,
 you'll be presented with a numbered list of classes that implement that
 method.  Indicate your choice by number, or type &lsquo;<samp><span class="samp">0</span></samp>&rsquo; to exit if
 none apply.

    <p>As another example, to clear a breakpoint established at the
 <code>makeKeyAndOrderFront:</code> method of the <code>NSWindow</code> class, enter:

 <pre class="smallexample">     clear -[NSWindow makeKeyAndOrderFront:]
 </pre>
