looking to optimize / generalize irule

looked around some more and found an alternative which will do the trick i believe, would this be acceptable code or is there something to change / make better?

 

 

please dont focus on the specifics, used variables might not make sense, it is the general idea.

 

class all_app_classes {
  class_app1
  class_app2
}

class class_app1 {
"ip" {"192.168.34.23"}
"port" {"45"}
"pool" {"pool_1"}
} 

class class_app2 {
{
"ip" {"192.145.224.23"}
"port" {"55"}
"pool" {"pool_2"}
} 

  set id [class startsearch all_app_classes]
  while { [class anymore all_app_classes $id] } {
    set x [class nextelement all_app_classes $id]
    set app_class [lindex $x 0]
    log local0. "$app_class"
    
    if { [TCP::local_port] == [class match -value port equals $app_class] and [IP::client_addr] == [class match -value ip equals $app_class] } {
      log local0. "$app_class is the right class"
      set saved_class $app_class
    }
  }

  pool [class match -value pool equals $saved_class]
