the function allows the user to increase the payout for a specific request
addTip(uint _requestId, uint _tip)
where: * _requestId is the ID for the value to be mined * _tip is the amount the requester is willing to pay to get on the queue
To read data, users will need to call these two functions:
the function allows the user to read the data for the given request ID and timestamp
retrieveData(uint _requestId, uint _timestamp)
where:
_requestId -- is the request ID
_timestamp -- is the unix timestamp to retrieve a value from
the function allows the user to read data from the latest request ID and timestamp mined.
getLastNewValue()
This is an example of a function that would need to be added to a contract so that it can read data from an oracle contact if the contract holds Tributes:
contract Oracle is usingTellor {...function getLastNewValue() public returns(uint,bool) {(value,ifRetrieve) = getLastNewValue();return (value, ifRetreive);...}
