Explanation needed

[AntonAleksandrov13]

In this file following line is present: for (int i = 0; i < numPieces / 2; i++) { tracker.setComplete(i, true); }

I would like some explanation what it actually does, since docs for this method are not present.

[gubatron]

simply tracks the piece as complete/incomplete:

private final boolean[] complete;

public void setComplete(int pieceIndex, boolean complete) {
        this.complete[pieceIndex] = complete;
}

As the name of the class implies "PieceTracker" it's just to track piece status.

Hope this helps.

@gubatron Suppose I am completely new to world of torrents, how should I go about learning how to use your library? Are there any resources that I can use for reference?
