package require XOTcl 1 1; namespace import -force xotcl::*
package require xotcl::actiweb::htmlPlace
package require xotcl::actiweb::webDocument

### Instantiate an Html place with the name receiver
HtmlPlace ::receiver -port 8093  -allowExit exit

### Define a class solely for counting
Class Counter -parameter {{count 1}}
Counter instproc increment {} {    ;### counter method
  my incr count
}

### Define a special WebCounter as a specialization of the Counter class 
Class WebCounter -superclass {Counter HtmlDocument}
WebCounter instproc init args {    ;### Constructor
  next
  my persistent count              ;### make count variable persistent
  ::receiver exportObjs [self]     ;### export the counter object
  my exportProcs increment         ;### export increment method
}
WebCounter instproc default {} {  ;### Method for updating HTML page
  set objName [string trimleft [self] :]
  return "The value in $objName is [my set count].<p>
	Increment Counter<p>
	
Last Update: [clock format [clock seconds] -format %m/%d/%y-%H:%M]
	\n"
}
WebCounter instproc increment {} { ;### exported increment method
  next                             ;### call superclasses' increment
  my default                      ;### display the result as HTML
}

### Create two web counter instances with the names c1 and c2
WebCounter c1
WebCounter c2

### Start event loop and handle connections
receiver startEventLoop
