Suggestion:
=========
A class wrapper for the string type in Vala, in order to avoid
duplication of data in assignments (which would yield an unnecessarily
huge memory usage when processing a large amount of text with a lot of
assignments).
if you compare the C code generated by Vala for:
1)
///
class String {
public string s;
}
void main (string[] argv) {
String a = new String();
a.s = "hello";
String b = a;
stdout.printf("a.s = %s\n", a.s);
stdout.printf("b.s = %s\n", b.s);
}
///
To :
2) the C code generated by Vala for:
///
void main (string[] argv) {
string a = "hello";
string b = a;
stdout.printf("a = %p\n", &a);
stdout.printf("b = %p\n", &b);
}
///
You will notice that in the second case (the naive straightforward
formulation) the data is duplicated (passed by value in the
assignment) whereas in the first case (which uses a class wrapper) the
object a is assigned to b by reference (not by value, i.e. the data is
not duplicated)
