Constructor Detail

FutureGet

public FutureGet(DHTBuilder<?> builder)

Default constructor.

FutureGet

public FutureGet(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

setReceivedData

public void setReceivedData(Map<PeerAddress,Map<Number640,Data>> rawData)

Finish the future and set the keys and data that have been received.

Parameters:

rawData - The keys and data that have been received with information from which peer it has been received.

getRawData

public Map<PeerAddress,Map<Number640,Data>> getRawData()

Returns the raw data from the get operation.

Returns:

The raw data and the information which peer has been contacted

getDataMap

public Map<Number640,Data> getDataMap()

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

Returns:

The evaluated data that have been received.

getData

public Data getData()

Returns:

The first data object from get() after evaluation.

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.
