Method Detail

initSelector

public void initSelector(int numPieces)

Description copied from interface: PieceSelector

Init any structures to iterate through numPieces pieces in some iteration order

Parameters:

numPieces - the number of pieces total

getIterationIdx

protected int getIterationIdx(int i)

Overrides:

getIterationIdx in class RarestFirstSelector

getNextPieces

public IntStream getNextPieces(BitSet relevantChunks,
                               PieceStatistics pieceStatistics)

Description copied from interface: PieceSelector

Select pieces based on the chunks which are relevant. Relevant means that the peer we are selecting pieces for has this chunk and we do not have this chunk locally

Specified by:

getNextPieces in interface PieceSelector

Overrides:

getNextPieces in class RarestFirstSelector

Parameters:

relevantChunks - the relevant chunks to chose (in the peer's completed list,

pieceStatistics - the piece statistics

Returns:

the stream of the next pieces to get
