<h3 class="section">3.4 Cacheing and Dispatch Functions</h3>
|
|
|
|
<p><code>SB-PCL::CACHING</code> functions simply cache effective methods as a
|
|
function of argument wrappers, while <code>SB-PCL::DISPATCH</code> functions
|
|
have code that computes the actual dispatch. <code>SB-PCL::CHECKING</code>
|
|
functions have a cache, but on cache misses will recompute whether or
|
|
not to generate a <code>SB-PCL::CACHING</code> or <code>SB-PCL::DISPATCH</code>
|
|
function.
|
|
|
|
<p>(FIXME: I'm actually not certain about the above paragraph. Read the
|
|
code again and see if it makes any more sense.)
