Value

function

Provides a constructor function to be used to provide a default value for a property.

`Value`

A constructor function can be provided that is called to create a default value used for this property. This constructor will be invoked with new for each created instance. The default value is created on demand when the property is read for the first time.

Specify Value like:

prop: {
    Value: Array
},
person: {
    Value: Person
}

Use

var Address = DefineMap.extend({
    street: {type: "string", value: "321 Longbow"},
    city: {type: "string", value: "Dallas"}
});

var Direction = DefineMap.extend({
    from: {Type: Address, Value: Address},
    to: {Type: Address, Value: Address}
});

var direction = new Direction({
    to: {street: "2070 N. Stave"}
});

direction.from.street //-> "321 Longbow"
direction.to.street   //-> "2070 N. Stave"
