latestAnswer
int256 latestAnswer
The latest answer reported by the aggregator.
latestTimestamp
uint256 latestTimestamp
The timestamp of the latest answer.
latestRound
uint256 latestRound
The latest round ID.
minAnswer
int192 minAnswer
The minimum answer the aggregator is allowed to report.
maxAnswer
int192 maxAnswer
The maximum answer the aggregator is allowed to report.
getAnswer
mapping(uint256 => int256) getAnswer
Mapping to get the answer for a specific round ID.
getTimestamp
mapping(uint256 => uint256) getTimestamp
Mapping to get the timestamp for a specific round ID.
