Method Detail

resolve

TResolved resolve()
                  throws DigestMismatchException

This Method resolves the responses that are passed in . for example : if its write response then all we get is true or false return values which implies if the writes were successful but for reads its more complicated you need to look at the responses and then based on differences schedule repairs . Hence you need to derive a response resolver based on your needs from this interface.

Throws:

DigestMismatchException

isDataPresent

boolean isDataPresent()

getData

TResolved getData()

returns the data response without comparing with any digests

preprocess

void preprocess(MessageIn<TMessage> message)

getMessages

java.lang.Iterable<MessageIn<TMessage>> getMessages()
