MethodWhitelist

Managing and retrieving whitelisted method selectors

SENTINEL_SELECTOR

bytes4 SENTINEL_SELECTOR

Special selector value threated as sentinel

_restrictedMethods

mapping(bytes4 => bool) _restrictedMethods

This is applied to all tokens in collection

Method selector to boolean if method whitelisting is restricted

_whitelistedMethods

mapping(uint256 => struct IMethodWhitelist.Whitelisted[]) _whitelistedMethods

This is applied per token

Token ID to array of whitelisted method selectors

_selectorToIndex

mapping(uint256 => mapping(bytes4 => uint256)) _selectorToIndex

If index is bigger then sentinel index is threated as invalid value
