.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
package require TclOO
|
||
|
|
|
||
|
|
\fBmy\fI methodName\fR ?\fIarg ...\fR?

.SH DESCRIPTION
|
||
|
|
.PP
|
||
|
|
The \fBmy\fR command is used to allow methods of objects to invoke any method
|
||
|
|
of the object (or its class). In particular, the set of valid values for
|
||
|
|
\fImethodName\fR is the set of all methods supported by an object and its
|
||
|
|
superclasses, including those that are not exported. The object upon which the
|
||
|
|
method is invoked is always the one that is the current context of the method
|
||
|
|
(i.e. the object that is returned by \fBself object\fR) from which the
|
||
|
|
\fBmy\fR command is invoked.
|
||
|
|
.PP
|
||
|
|
Each object has its own \fBmy\fR command, contained in its instance namespace.
|
||
|
|
.SH EXAMPLES
|
||
|
|
.PP
|
||
|
|
This example shows basic use of \fBmy\fR to use the \fBvariables\fR method of
|
||
|
|
the \fBoo::object\fR class, which is not publicly visible by default:
|
||
|
|
.PP
|
||
|
|
.CS
|
||
|
|
oo::class create c {
|
||
|
|
method count {} {
|
||
|
|
\fBmy\fR variable counter
|
||
|
|
puts [incr counter]
|
||
|
|
}
|
||
|
|
}
|
||
|
|
c create o
|
||
|
|
o count \fI\(-> prints "1"\fR
|
||
|
|
o count \fI\(-> prints "2"\fR
|
