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.
