Something like the following:
ref example:
void changeString(ref String str) {
str = "def";
}
void main() {
String abc = "abc";
changeString(ref abc);
System.out.println(abc); //prints "def"
}
out example:
void setString(out String str) {
str = "def";
}
void main() {
String abc;
changeString(out abc);
System.out.println(abc); //prints "def"
}
