itcl User Commands - delete
NAME
delete - delete things in the interpreter
SYNOPSIS
delete option ?arg arg ...?
DESCRIPTION
The delete command is used to delete things in the inter-
preter. It is implemented as an ensemble, so extensions can
add their own options and extend the behavior of this com-
mand. By default, the delete command handles the destruc-
tion of namespaces.
The option argument determines what action is carried out by
the command. The legal options (which may be abbreviated)
are:
delete class name ?name...?
Deletes one or more [incr Tcl] classes called name.
This deletes all objects in the class, and all derived
classes as well.
If an error is encountered while destructing an object,
it will prevent the destruction of the class and any
remaining objects. To destroy the entire class without
regard for errors, use the "delete namespace" command.
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 com-
mand from the interpreter.
If the access command for an object resides in another
namespace, then its qualified name can be used:
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.
