I thinking if the Object type will be deprecated in the future... I hope
not.
As Free Pascal still writes on its flag that it is compatible to Turbo
Pascal I doubt that it will be deprecated (also there is quite some code in
the compiler and also in some packages which use object).
Good to know ;)
And, as somebody asked, what the advantages (performance?) using
Object instead Class?
They are basically similar to "records with methods" (which we now have
as well...) if you use them directly (this means: not as pointer types):
they are located on the stack and nested objects are part of the memory
structure of the object. But if you use references to objects you work
more like with classes as you have constructors, virtual methods and the
objects are then located on the heap (thus you need to care for the
memory management yourself).
I like to use Object to group routines instead of using
procedure/functions... as a 'namespace' to not use the unit name as a
prefix.
I would to know what do you, guys, think about it.
I haven't implemented objects yet myself (besides testing whether some
feature that was implemented for classes works for objects as well -
which many features do!) and I also haven't used the new advanced
records, so I'm the wrong person to ask this question ;)
