List

A can.Model's List property is the type of List returned from findAll. For example:

Task = can.Model.extend({
  findAll: "/tasks"
},{})

Task.findAll({}, function(tasks){
  tasks instanceof Task.List //-> true
})

Overwrite a Model's List property to add custom behavior to the lists provided to findAll like:

Task = can.Model.extend({
  findAll: "/tasks"
},{})
Task.List = Task.List.extend({
  completed: function(){
    var count = 0;
    this.each(function(task){
      if( task.attr("completed") ) count++;
    })
    return count;
  }
})

Task.findAll({}, function(tasks){
  tasks.completed() //-> 3
})

When can.Model is extended, can.Model.List is extended and set as the extended Model's List property. The extended list's Map property is set to the extended Model. For example:

Task = can.Model.extend({
  findAll: "/tasks"
},{})
Task.List.Map //-> Task
