Methods for the generic function <tt>reinitialize-instance</tt> may be defined to specify
|
||
|
|
actions to be taken when an instance is updated. If only <tt>:after</tt>
|
||
|
|
methods for <tt>reinitialize-instance</tt> are defined, they will be run
|
||
|
|
after the system-supplied primary method for initialization and
|
||
|
|
therefore will not interfere with the default behavior of
|
||
|
|
<tt>reinitialize-instance</tt>.
|

<P>

|

Methods for <tt>shared-initialize</tt> may be defined to customize class
|
||
|
|
redefinition (see section <A HREF="node297.html#SharedInitializeSECTION">28.1.9.5</A>).
