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.
