NAME

my — invoke any method of current object

SYNOPSIS

package require TclOO

my methodName ?arg ...?

DESCRIPTION

The my 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 methodName 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 self object) from which the my command is invoked.

Each object has its own my command, contained in its instance namespace.

EXAMPLES

This example shows basic use of my to use the variables method of the oo::object class, which is not publicly visible by default: 

oo::class create c {
    method count {} {
        my variable counter
        puts [incr counter]
    }
}
c create o
o count              → prints "1"
o count              → prints "2"
o count              → prints "3"
