Constructor Detail

FutureSend

public FutureSend(DHTBuilder<?> builder)

Default constructor.

FutureSend

public FutureSend(DHTBuilder<?> builder,
          int min,
          EvaluatingSchemeDHT evaluationScheme)

Creates a new DHT future object that keeps track of the status of the DHT operations.

Parameters:

min - The minimum of expected results

evaluationScheme - The scheme to evaluate results from multiple peers

Method Detail

directData1

public void directData1(Map<PeerAddress,io.netty.buffer.ByteBuf> rawChannels)

Finish the future and set the keys and data that have send directly using the Netty buffer.

Parameters:

rawChannels - The raw data that have been sent directly with information on which peer it has been sent

directData2

public void directData2(Map<PeerAddress,Object> rawObjects)

Finish the future and set the keys and data that have send directly using an object.

Parameters:

rawObjects - The objects that have been sent directly with information on which peer it has been sent

rawDirectData1

public Map<PeerAddress,io.netty.buffer.ByteBuf> rawDirectData1()

Return raw data from send_dircet (Netty buffer).

Returns:

The raw data from send_dircet and the information which peer has been contacted

rawDirectData2

public Map<PeerAddress,Object> rawDirectData2()

Return raw data from send_dircet (Object).

Returns:

The raw data from send_dircet and the information which peer has been contacted

object

public Object object()

Return the data from send_direct (Object) after evaluation. The evaluation gets rid of the PeerAddress information, by either a majority vote or cumulation.

Returns:

The data that have been received.

channelBuffer

public io.netty.buffer.ByteBuf channelBuffer()

Return the data from send_direct (Netty buffer) after evaluation. The evaluation gets rid of the PeerAddress information, by either a majority vote or cumulation.

Returns:

The data that have been received.

isMinReached

public boolean isMinReached()

Checks if the minimum of expected results have been reached. This flag is also used for determining the success or failure of this future for put and send_direct.

Returns:

True, if expected minimum results have been reached.
