Modify/extend objects at runtime

[bmmptlgc]

I need modify/extend objects at runtime. For example,

I want to extend an Order object returned by an API, so that the serialized JSON response would go from:

{
	"orderId": "abc",
	"price": 100,
	"orderItems": [
		{
			"orderItemId": "def",
			"price": 55
		},
		{
			"orderItemId": "ghi",
			"price": 45
		}
	]
}

to:

{
	"@id": "https://someurl/api/orders/abc",
	"orderId": "abc",
	"price": 100,
	"orderItems": [
		{
			"@id": "https://someurl/api/orders/abc/order-item/def",
			"orderItemId": "def",
			"price": 55
		},
		{
			"@id": "https://someurl/api/orders/abc/order-item/ghi",
			"orderItemId": "ghi",
			"price": 45
		}
	]
}

I am able to accomplish this using reflection, but was wondering if I can simplify the code with fasterflect.

Essentially, I need to an Id field to OrderItem with a JsonPropertyName attribute with the value "@id". I need to do the same thing to the Order object, plus add a couple more fields I didn't include in the example above, for simplicity.

Can fasterflect do this?
