11The Meta Object Protocol (MOP), which isn't part of the language standard but is
supported by most Common Lisp implementations, provides a function, class-prototype, that returns an instance of a class that can be used to access class slots.
9One consequence of defining a SETF function--say, (setf
foo)--is that if you also define the corresponding accessor
function, foo in this case, you can use all the modify macros built
upon SETF, such as INCF, DECF, PUSH, and POP, on the new
kind of place. In the latter case, the slot shared by instances
of the sub-subclass is different than the slot shared by the
original superclass. This can happen either because a subclass includes a slot specifier with the same
name as a slot specified in a superclass or because multiple
superclasses specify slots with the same name. Inherited :reader,
:writer, and :accessor options aren't included in the merged slot specifier since the methods created by the superclass's
DEFCLASS will already apply to the new class.
While they were in high school, lead vocalist and guitarist Adam Levine,
keyboardist Jesse Carmichael, bass guitarist Mickey Madden, and drummer
Ryan Dusick formed a garage band called Kara's Flowers and released one album
in 1997. After a brief period they re-formed with guitarist
James Valentine, and pursued a new, more pop-oriented direction as Maroon 5.
In 2004 they released their debut album Songs About Jane, which
contained four hit singles: "Harder to Breathe", "This Love", "She Will Be Loved" and "Sunday Morning"; it also enjoyed major chart
success, going gold, platinum, and triple platinum in many countries around the world. |
