copy(n) TclOO Commands copy(n)______________________________________________________________________________NAMEoo::copy - create copies of objects and classes
SYNOPSIS
package require TclOO
oo::copy sourceObject ?targetObject?
_________________________________________________________________DESCRIPTION
The oo::copy command creates a copy of an object or class. It takes the
name of the object or class to be copied, sourceObject, and optionally
the name of the object or class to create, targetObject, which will be
resolved relative to the current namespace if not an absolute qualified
name. If targetObject is omitted, a new name is chosen. The copied
object will be of the same class as the source object, and will have
all its per-object methods copied. If it is a class, it will also have
all the class methods in the class copied, but it will not have any of
its instances copied. The contents of the source object's private
namespace will not be copied; it is up to the caller to do this. The
result of this command will be the fully-qualified name of the new
object or class.
EXAMPLES
This example creates an object, copies it, modifies the source object,
and then demonstrates that the copied object is indeed a copy.
oo::object create src
oo::define src method msg {} {puts foo}
oo::copy src dst
oo::define src method msg {} {puts bar}
src msg → prints "bar"
dst msg → prints "foo"
