tcl7.6 User Commands - protected
NAME
protected - create commands/variables with "protected"
access
SYNOPSIS
protected command ?arg arg ...?
DESCRIPTION
Sets the protection level for new commands/variables to
"protected" and then evaluates the remaining arguments.
Note that the default protection level for
commands/variables is "public". Commands and variables can
also be "private".
The command argument may be a command name like proc or
variable, or a script full of command/variable declarations.
Any command that creates another command or variable can be
used in conjunction with the protected command. For exam-
ple, if widget commands are executed via "protected", the
widget access commands will be protected.
Protected commands/variables are accessible in the namespace
where they are defined, and in any other namespace that
imports the defining namespace in a "protected" mode. See
the import command for details concerning the import list.
EXAMPLE
namespace foo {
protected {
variable x 0
variable y 1
}
protected proc check {} {
global x y
return "$x $y"
}
}
import add {foo protected}
foo::check
