Functions

checkOnERC1155Received

Performs an acceptance check for the provided operator by calling IERC1155Receiver-onERC1155Received 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 {IERC1155Receiver-onERC1155Received} and return the acceptance magic value to accept the transfer.

function checkOnERC1155Received(
    address operator,
    address from,
    address to,
    uint256 id,
    uint256 value,
    bytes memory data
) internal;

checkOnERC1155BatchReceived

Performs a batch acceptance check for the provided operator by calling IERC1155Receiver-onERC1155BatchReceived 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 {IERC1155Receiver-onERC1155Received} and return the acceptance magic value to accept the transfer.

function checkOnERC1155BatchReceived(
    address operator,
    address from,
    address to,
    uint256[] memory ids,
    uint256[] memory values,
    bytes memory data
) internal;
