PropDefinition

By defining a wildcard property like "*" on the prototype, this will supply a default behavior for every property. The default wildcard "*" definition makes every property run through the "observable" types converter. It looks like:

"*": {
  type: "observable"
}

Setting the wildcard is useful when every property on a map instance should behave in a particular way. For example, for map types used with can-route:

var MyMap = DefineMap.extend({
  "*": {
    type: "stringOrObservable"
  }
})

Or if you want to turn off implicit conversion of Objects and Arrays to DefineMap and DefineLists:

var MyMap = DefineMap.extend({
  "*": {
    type: "*"
  }
})
