NAME¶
delete - delete things in the interpreter
SYNOPSIS¶
itcl::delete option ?
arg arg ...?
DESCRIPTION¶
The
delete command is used to delete things in the interpreter. It is
implemented as an ensemble, so extensions can add their own options and extend
the behavior of this command. By default, the
delete command handles
the destruction 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 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.
