Available since v3.1.
Methods
onERC1155BatchReceived
function onERC1155BatchReceived(address operator, address from, uint256[] ids, uint256[] values, bytes data) external nonpayable returns (bytes4)
Handles the receipt of a multiple ERC1155 token types. This function is called at the end of a safeBatchTransferFrom after the balances have been updated. NOTE: To accept the transfer(s), this must return bytes4(keccak256("onERC1155BatchReceived(address,address,uint256[],uint256[],bytes)")) (i.e. 0xbc197c81, or its own function selector).
Parameters
| Name | Type | Description |
|---|---|---|
| operator | address | The address which initiated the batch transfer (i.e. msg.sender) |
| from | address | The address which previously owned the token |
| ids | uint256[] | An array containing ids of each token being transferred (order and length must match values array) |
| values | uint256[] | An array containing amounts of each token being transferred (order and length must match ids array) |
| data | bytes | Additional data with no specified format |
Returns
| Name | Type | Description |
|---|---|---|
| _0 | bytes4 | bytes4(keccak256("onERC1155BatchReceived(address,address,uint256[],uint256[],bytes)")) if transfer is allowed |
