blessREF
,CLASSNAME
blessREF
This function looks up the item pointed to by reference
REF
and tells the item that it is now an object in the
CLASSNAME
package - or the current package if no
CLASSNAME
is specified, which is often the case. It returns the reference for convenience, since a
bless
is often the last thing in a constructor function. (Always use the two-argument version if the constructor doing the blessing might be inherited by a derived class. In such cases, the class you want to bless your object into will normally be found as the first argument to the constructor in question.) See "Objects" in
Chapter 5,
Packages, Modules, and Object Classes
for more about the blessing (and blessings) of objects.
