    address _core,
    contract ICollateralizationOracleWrapper _oracleWrapper,
    uint256 _frequency,
    uint256 _deviationThresholdBasisPoints
) public

The constructor for CollateralizationOracleGuardian @param _core the core address to reference @param _oracleWrapper the instance of CollateralizationOracleWrapper @param _frequency the maximum frequency a guardian can update the cache @param _deviationThresholdBasisPoints the maximum percent change in a cache value for a given update

Parameters

Name	Type	Description
_core	address
_oracleWrapper	contract ICollateralizationOracleWrapper
_frequency	uint256
_deviationThresholdBasisPoints	uint256

setCache

function setCache(
    uint256 protocolControlledValue,
    uint256 userCirculatingFei
) external

guardian set the cache values on collateralization oracle

make sure to pause the CR oracle wrapper or else the set value would be overwritten on next update
