↘ Derived Contracts: ERC165
IERC165
Interface of the ERC165 standard, as defined in the https://eips.ethereum.org/EIPS/eip-165[EIP]. Implementers can declare support of contract interfaces, which can then be queried by others ({ERC165Checker}). For an implementation, see {ERC165}.
Returns true if this contract implements the interface defined by
interfaceId. See the corresponding
https://eips.ethereum.org/EIPS/eip-165#how-interfaces-are-identified[EIP section]
to learn more about how these ids are created.
This function call must use less than 30 000 gas.
