Tellor Functions

Available Tellor Functions

When your contract inherits the usingtellor helper contract, it has access to the following functions:

getDataAfter

Retrieves the next value for a given queryId after a given timestamp
function getDataAfter(bytes32 _queryId, uint256 _timestamp)
public
view
returns (bytes memory _value, uint256 _timestampRetrieved);

getDataBefore

Finds the most recent submission for a given queryId before a specific timestamp.
  • It is recommended that you use this function with a buffer time when retrieving oracle values. This allows time for bad values to be disputed.
function getDataBefore(bytes32 _queryId, uint256 _timestamp)
public
view
returns (bytes memory _value, uint256 _timestampRetrieved);

getIndexForDataAfter

Returns the index of the next value reported for a given queryId after a given timestamp.
function getIndexForDataAfter(bytes32 _queryId, uint256 _timestamp)
public
view
returns (bool _found, uint256 _index);

getIndexForDataBefore

Returns the index of the most recent value reported for a given queryId before a given timestamp.
function getIndexForDataBefore(bytes32 _queryId, uint256 _timestamp)
public
view
returns (bool _found, uint256 _index);

getMultipleValuesBefore

Returns the multiple most recent values for a given queryId before a given timestamp.
function getMultipleValuesBefore(
bytes32 _queryId,
uint256 _timestamp,
uint256 _maxAge,
uint256 _maxCount
)
public
view
returns (bytes[] memory _values, uint256[] memory _timestamps);

getNewValueCountbyQueryId

Returns the total number of values submitted for a given queryId
function getNewValueCountbyQueryId(bytes32 _queryId)
public
view
returns (uint256);

getReporterByTimestamp

Retrieves the address of the reporter for a given queryId and timestamp.
function getReporterByTimestamp(bytes32 _queryId, uint256 _timestamp)
public
view
returns (address);

getTimestampbyQueryIdandIndex

Returns the timestamp at a specific index for a given queryId.
  • Values start at the 0 index
function getTimestampbyQueryIdandIndex(bytes32 _queryId, uint256 _index)
public
view
returns (uint256);

isInDispute

Determines whether a specific value with a given queryId and timestamp has been disputed
function isInDispute(bytes32 _queryId, uint256 _timestamp)
public
view
returns (bool);

retrieveData

Retrieves a specific value by queryId and timestamp
function retrieveData(bytes32 _queryId, uint256 _timestamp)
public
view
returns (bytes memory);
