Specman e: How to use deep_copy on a structure list?
I have a my_list_1
(list of structures) which is defined like this:
struct my_struct {
something[2] : list of int;
something_else[2] : list of uint;
};
...
my_list_1[10] : list of my_struct;
I need to copy this list to a local variable in a method:
foo_method() is {
var my_list_2 : list of my_struct;
my_list_2 = deep_copy(my_list_1);
...
};
Compilation error:
*** Error: 'my_list_1' is of type 'list of my_struct', while
expecting type 'any_struct'.
...
my_list_2 = deep_copy(my_list_1);
All spellings deep_copy()
I tried to cause a compilation error ... How do I copy a list of structures into a local variable? Thank you for your help.

You cannot directly use deep_copy(...)
to copy a list. If you look in the docs, deep_copy(...)
takes a single type parameter any_struct
and returns one instance of a struct. You have to use it in a loop for each
:
extend sys {
my_list_1[10] : list of my_struct;
run() is also {
foo_method();
};
foo_method() is {
var my_list_2 : list of my_struct;
for each (elem) in my_list_1 {
my_list_2.add(deep_copy(elem));
};
print my_list_1[0], my_list_2[0];
print my_list_1[1], my_list_2[1];
};
};
