TwitterValue
Provides a constructor function to be used to provide a default value for a certain property of a Map. This constructor will be invoked with new each time a new instance of the map is created.
constructorFunc
A constructor function can be provided that is called to create a default value used for this property, like:
define: {
prop: {
Value: Array
},
person: {
Value: Person
}
}
Similar to value, this uppercase version provides a mechanism for providing a default value. If the default value is an object, providing a constructor is a good way to ensure a copy is made for each instance.
