class without regard for errors, use the " delete
- delete object name ?name...?
- Deletes one or more [incr Tcl] objects called name.
An object is deleted by invoking all destructors in its class hierarchy,
in order from most- to least-specific. If all destructors are successful,
data associated with the object is deleted and the name is removed
as a command from the interpreter.
If the access command for an object resides in another namespace, then its
qualified name can be used:
itcl::delete object foo::bar::x
If an error is encountered while destructing an object, the delete
command is aborted and the object remains alive. To destroy an object without
regard for errors, use the " rename
" command to destroy the
object access command.
- delete namespace name ?name...?
- Deletes one or more namespaces called name. This deletes all
commands and variables in the namespace, and deletes all child namespaces
as well. When a namespace is deleted, it is automatically removed from the
import lists of all other namespaces.
