I ran into this block of code, and there is this one line I don't quit understand the meaning or what it is doing.
public Digraph(In in) {
this(in.readInt());
int E = in.readInt();
for (int i = 0; i < E; i++) {
int v = in.readInt();
int w = in.readInt();
addEdge(v, w);
}
}
I understand what this.method()
or this.variable
are, but what is this()
?
