dispatch algorithm used in Java 5. In AspectJ 5, the target method
of a call is selected according to the following algorithm:</p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem">Attempt to locate a matching method or inter-type declared
method without considering
autoboxing, unboxing, or vararg invocations.</li><li class="listitem">If no match is found, try again considering autoboxing
and unboxing.</li><li class="listitem">Finally try again considering both autoboxing, unboxing,
and varargs.</li></ol></div><p>One consequence is that a directly matching inter-type declared
method will take precedence over a method declared locally in the
target class but that only matches via autoboxing.</p></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="autoboxing-in-aspectj5.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="autoboxing.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="covariance.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Autoboxing and Join Point matching in AspectJ 5 </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> Chapter 5.
