.SH SYNOPSIS
|
| 16 |
|
|
\fBdelete \fIoption\fR ?\fIarg arg ...\fR?

.SH DESCRIPTION
|
| 20 |
|
|
.PP
|
| 21 |
|
|
The \fBdelete\fR command is used to delete things in the interpreter.
|
| 22 |
|
|
It is implemented as an ensemble, so extensions can add their own
|
| 23 |
|
|
options and extend the behavior of this command. By default, the
|
| 24 |
|
|
\fBdelete\fR command handles the destruction of namespaces.
|
| 25 |
|
|
.PP
|
| 26 |
|
|
The \fIoption\fR argument determines what action is carried out
|
| 27 |
|
|
by the command. The legal \fIoptions\fR (which may be abbreviated)
|
| 28 |
|
|
are:
|
| 29 |
|
|
.TP
|
| 30 |
|
|
\fBdelete class \fIname\fR ?\fIname...\fR?
|
| 31 |
|
|
Deletes one or more \fB[incr\ Tcl]\fR classes called \fIname\fR.
|
| 32 |
|
|
This deletes all objects in the class, and all derived classes
|
| 33 |
|
|
as well.
|
| 34 |
|
|
.sp
|
| 35 |
|
|
If an error is encountered while destructing an object, it will
|
| 36 |
|
|
prevent the destruction of the class and any remaining objects.
|
| 37 |
|
|
To destroy the entire class without regard for errors, use the
|
| 38 |
|
|
"\fBdelete namespace\fR" command.
|
| 39 |
|
|
.TP
|
| 40 |
|
|
\fBdelete object \fIname\fR ?\fIname...\fR?
|
| 41 |
|
|
Deletes one or more \fB[incr\ Tcl]\fR objects called \fIname\fR.
|
| 42 |
|
|
An object is deleted by invoking all destructors in its class
|
| 43 |
|
|
hierarchy, in order from most- to least-specific. If all destructors
|
| 44 |
|
|
are successful, data associated with the object is deleted and
|
| 45 |
|
|
the \fIname\fR is removed as a command from the interpreter.
|
| 46 |
|
|
.sp
|
| 47 |
|
|
If the access command for an object resides in another namespace,
|
| 48 |
|
|
then its qualified name can be used:
|
| 49 |
|
|
.CS
|
| 50 |
|
|
delete object foo::bar::x
|
| 51 |
|
|
.CE
|
| 52 |
|
|
If an error is encountered while destructing an object, the
|
| 53 |
|
|
\fBdelete\fR command is aborted and the object remains alive.
|
| 54 |
|
|
To destroy an object without regard for errors, use the
|
| 55 |
|
|
"\fBrename\fR" command to destroy the object access command.
|
| 56 |
|
|
.TP
|
| 57 |
|
|
\fBdelete namespace \fIname\fR ?\fIname...\fR?
|
| 58 |
|
|
Deletes one or more namespaces called \fIname\fR. This deletes
|
| 59 |
|
|
all commands and variables in the namespace, and deletes all
|
| 60 |
|
|
child namespaces as well. When a namespace is deleted, it is
|
| 61 |
|
|
automatically removed from the import lists of all other namespaces.
