<p>The procedure <code class="code">goops-error</code> is called to raise an appropriate error
|
|
by the default methods of the following generic functions:
|
|
</p>
|
|
<ul class="itemize mark-bullet">
|
|
<li><code class="code">slot-missing</code> (see <a class="pxref" href="Accessing-Slots.html">slot-missing</a>)
|
|
|
|
</li><li><code class="code">slot-unbound</code> (see <a class="pxref" href="Accessing-Slots.html">slot-unbound</a>)
|
|
|
|
</li><li><code class="code">no-method</code> (see <a class="pxref" href="Handling-Invocation-Errors.html">no-method</a>)
|
|
|
|
</li><li><code class="code">no-applicable-method</code> (see <a class="pxref" href="Handling-Invocation-Errors.html">no-applicable-method</a>)
|
|
|
|
</li><li><code class="code">no-next-method</code> (see <a class="pxref" href="Handling-Invocation-Errors.html">no-next-method</a>)
|
|
</li></ul>
|
|
|
|
<p>If you customize these functions for particular classes or metaclasses,
|
|
you may still want to use <code class="code">goops-error</code> to signal any error
|
|
conditions that you detect.
