Stores data on a remote peer. Overwrites data if the data already exists. This is an RPC.

Parameters:

remotePeer - The remote peer to store the data

locationKey - The location of the data

domainKey - The domain of the data

dataMap - The map with the content key and data

protectDomain - Set to true if the domain should be set to protected. This means that this domain is flagged an a public key is stored for this entry. An update or removal can only be made with the matching private key.

protectEntry - Set to true if the entry should be set to protected. This means that this domain is flagged an a public key is stored for this entry. An update or removal can only be made with the matching private key.

                                    boolean forceUDP)

Compares and puts data on a peer. It first compares the hashes that the user provided on the remote peer, and if the hashes match, the data is stored. If the flag partial put has been set, then it will store those data where the hashes match and ignore the others. This is an RPC.

Parameters:

remotePeer - The remote peer to store the data

locationKey - The location key

domainKey - The domain key

hashDataMap - The map with the data and the hashes to compare to

futureSuccessEvaluator - The evaluator that determines if a future was a success.

protectDomain - Protect the domain

protectEntry - Protect the entry

signMessage - Set to true if the message should be signed. For protecting an entry, this needs to be set to true.

partialPut - Set to true if partial puts should be allowed. If set to false, then the complete map must match the hash, otherwise it wont be stored.

channelCreator - The channel creator

forceUDP - Set to true if the communication should be UDP, default is TCP

Returns:

FutureResponse that stores which content keys have been stored.

add

public FutureResponse add(PeerAddress remotePeer,
                          Number160 locationKey,
                          Number160 domainKey,
                          Collection<Data> dataSet,
                          boolean protectDomain,
                          boolean signMessage,
                          boolean list,
                          ChannelCreator channelCreator,
                          boolean forceUDP,
                          SenderCacheStrategy senderCacheStrategy)

Adds data on a remote peer. The main difference to #put(PeerAddress, Number160, Number160, Map, Type, boolean, ChannelCreator, boolean) and #putIfAbsent(PeerAddress, Number160, Number160, Map, boolean, boolean, boolean, ChannelCreator, boolean) is that it will convert the data collection to map. The key for the map will be the SHA-1 hash of the data. This is an RPC.

Parameters:

remotePeer - The remote peer to store the data

locationKey - The location key

domainKey - The domain key

dataSet - The set with data. This will be converted to a map. The key for the map is the SHA-1 of the data.

protectDomain - Set to true if the domain should be set to protected. This means that this domain is flagged an a public key is stored for this entry. An update or removal can only be made with the matching private key.

signMessage - Set to true if the message should be signed. For protecting an entry, this needs to be set to true.

channelCreator - The channel creator

forceUDP - Set to true if the communication should be UDP, default is TCP

Returns:

FutureResponse that stores which content keys have been stored.
