How can i access values in DList?
I save different objects of type "Property" in my DList, but
if i want to access them this way:
this.properties[0].value.start
i get:
Error: no [] operator overload for type DList!(Property)
Fixed, i just used Array!Property
DList implements what is known as a "(doubly) linked list". It is
a container type that is not capable of providing random acess.
As such, you cannot do "properties[0]". You can either access the
first ("front") value individually, or iterate your DList (via
its range interface "foreach(val; this.properties[]) {...}").
Array implements a basic contiguous sequence of elements (hence
provides RA).
It is important you understand what you are using, and which
container best fits your needs.
