NAME
local - create an object local to a procedure
SYNOPSIS
local className objName ?arg arg ...?
DESCRIPTION
The local command creates an [incr Tcl] object that is local to the current call frame. When the call frame goes away, the object is auto- matically deleted. This command is useful for creating objects that are local to a procedure. As a side effect, this command creates a variable named "itcl-local-xxx", where xxx is the name of the object that is created. This vari- able detects when the call frame is destroyed and automatically deletes the associated object.
EXAMPLE
In the following example, a simple "counter" object is used within the procedure "test". The counter is created as a local object, so it is automatically deleted each time the procedure exits. The puts statements included in the constructor/destructor show the object coming and going as the procedure is called. class counter { private variable count 0 constructor {} { puts "created: $this" } destructor { puts "deleted: $this" } method bump {{by 1}} { incr count $by } method get {} { return $count } } proc test {val} { local counter x for {set i 0} {$i < $val} {incr i} { x bump } return [x get] } set result [test 5] puts "test: $result" set result [test 10] puts "test: $result" puts "objects: [info objects]"
