                                     Number160 domainKey,

                                     boolean forceTCP)

Requests close neighbors from the remote peer. The remote peer may idicate if the data is present on that peer. This is an RPC.

Parameters:

remotePeer - The remote peer to send this request

locationKey - The location key

domainKey - The domain key

contentKeys - For get() and remove() one can provide the content keys and the remote peer indicates if those keys are on that peer.

type - The type of the neigbor request:

• REQUEST_1 for NEIGHBORS means check for put (no digest) for tracker and storage
• REQUEST_2 for NEIGHBORS means check for get (with digest) for storage
• REQUEST_3 for NEIGHBORS means check for get (with digest) for tracker
• REQUEST_4 for NEIGHBORS means check for put (with digest) for task

isDigest - Set to true to return a digest of the remote content

channelCreator - The channel creator that creates connections

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

Returns:

The future response to keep track of future events
