checkOnERC721Received

function checkOnERC721Received(address operator, address from, address to, uint256 tokenId, bytes data) internal

_Performs an acceptance check for the provided operator by calling {IERC721-onERC721Received} on the to address. The operator is generally the address that initiated the token transfer (i.e. msg.sender).

The acceptance call is not executed and treated as a no-op if the target address doesn't contain code (i.e. an EOA). Otherwise, the recipient must implement {IERC721Receiver-onERC721Received} and return the acceptance magic value to accept the transfer._
