PropDefinition

By defining a wildcard property ("#") on the prototype, this will supply a default behavior for items in the list. The default wildcard ("#") definition makes every item run through the "observable" types converter. It looks like:

"#": {
  type: "observable"
}

Setting the wildcard is useful when items should be converted to a particular type.

var Person = DefineMap.extend({ ... });

var People = DefineList.extend({
  "#": Person
});

The wildcard property has optional added and removed functions that will be called after an item is added or removed from the list with this being the list.

var People = DefineList.extend({
  "#": {
    added: function(itemsAdded, index) { ... },
    removed: function(itemsRemoved, index) { ... }
  }
});
