  instantiation 
 
    Producing  a  more  defined  version  of  some  object 
  by  replacing  variables  with  values  (or  other  variables). 
 
  1.  In  {object-oriented  programming},  producing  a  particular 
  {object}  from  its  {class  template}.  This  involves  allocation 
  of  a  structure  with  the  types  specified  by  the  template,  and 
  initialisation  of  {instance  variable}s  with  either  default 
  values  or  those  provided  by  the  class's  {constructor} 
  function. 
 
  2.  In  {unification},  (as  used  in  {logic  programming},  {type 
  checking}  and  {type  inference}),  binding  a  {logic  variable} 
  ({type  variable})  to  some  value  (type).
