extend

Parameters

1. name {String}:

   Provides an optional name for this type that will show up nicely in debuggers.

2. static {Object}:

   Static properties that are set directly on the constructor function.

3. prototype {Object<String,function|PropDefinition>}:

   A definition of the properties or methods on this type.

   If the property definition is a plain function, it's considered a method.

   var Person = DefineMap.extend({
     sayHi: function(){ console.log("hi"); }
   });
   
   var me = new Person();
   me.sayHi();
   

   If the property definition is a string, it's considered a type setting to be looked up in can-define.types.

   var Person = DefineMap.extend({
     age: 'number',
     isCool: 'boolean',
     hobbies: 'observable'
   });
   
   var me = new Person({age: '33', isCool: 'false', hobbies: ['js','bball']});
   me.age    //-> 33
   me.isCool //-> false
   me.hobbies instanceof DefineList //-> true
   

   If the property definition is a Constructor function, it's considered a Type setting.

   var Address = DefineMap.extend({
     zip: 'number'
   });
   var Person = DefineMap.extend({
     address: Address
   });
   
   var me = new Person({address: {zip: '60048'}});
   me.address.zip //-> 60048
   

   If the property is an object, it's considered to be a PropDefinition.

   var Person = DefineMap.extend({
     fullName: {
       get: function() {
         return this.first+" "+this.last;
       },
       set: function(newVal) {
         var parts = newVal.split(" ");
         this.first = parts[0];
         this.last = parts[1];
       }
     },
     // slick way of creating an 'inline' type.
     address: {
       Type: {
         zip: "number"
       }
     }
   });
   
   var me = new Person({fullName: "Rami Myer", address: {zip: '60048'}});
   me.first       //-> "Rami"
   me.address.zip //-> 60048
