Functions

Address of the non-delayed price source

Assumes that the price source is a valid IBaseOracle

function priceSource() external view returns (IBaseOracle _priceSource);

The next valid price feed, taking effect at the next updateResult call

function getNextResultWithValidity() external view returns (uint256 _result, bool _validity);

Returns

Name	Type	Description
`_result`	`uint256`	The value in 18 decimals format of the next price feed
`_validity`	`bool`	Whether the next price feed is valid or not

The delay in seconds that should elapse between updates

function updateDelay() external view returns (uint256 _updateDelay);

The timestamp of the last update

function lastUpdateTime() external view returns (uint256 _lastUpdateTime);

Indicates if a delay has passed since the last update

function shouldUpdate() external view returns (bool _ok);

Returns

Name	Type	Description
`_ok`	`bool`	Whether the oracle should be updated or not

Updates the current price with the last next price, and reads the next price feed

Will revert if the delay since last update has not elapsed

function updateResult() external returns (bool _success);

Returns

Name	Type	Description
`_success`	`bool`	Whether the update was successful or not

Emitted when the oracle is updated

event UpdateResult(uint256 _newMedian, uint256 _lastUpdateTime);

Throws if the provided price source address is null

error DelayedOracle_NullPriceSource();

Throws if the provided delay is null

error DelayedOracle_NullDelay();

Throws when trying to update the oracle before the delay has elapsed

error DelayedOracle_DelayHasNotElapsed();

Throws when trying to read the current value and it is invalid

error DelayedOracle_NoCurrentValue();
