ERC1155Asset

Methods

DEFAULT_ADMIN_ROLE

function DEFAULT_ADMIN_ROLE() external view returns (bytes32)

Returns

MINTER_ROLE

function MINTER_ROLE() external view returns (bytes32)

Returns

balanceOf

function balanceOf(address account, uint256 id) external view returns (uint256)

See {IERC1155-balanceOf}. Requirements: - account cannot be the zero address.

Parameters

Returns

balanceOfBatch

function balanceOfBatch(address[] accounts, uint256[] ids) external view returns (uint256[])

See {IERC1155-balanceOfBatch}. Requirements: - accounts and ids must have the same length.

Parameters

Returns

baseURI

function baseURI() external view returns (string)

Returns the base URI set via {_setBaseURI}.

Returns

contractURI

function contractURI() external view returns (string)

returns contract-level-metadata, See https://docs.opensea.io/docs/contract-level-metadata

Returns

getRoleAdmin

function getRoleAdmin(bytes32 role) external view returns (bytes32)

Returns the admin role that controls role. See {grantRole} and {revokeRole}. To change a role's admin, use {_setRoleAdmin}.

Parameters

Returns

grantRole

function grantRole(bytes32 role, address account) external nonpayable

Grants role to account. If account had not been already granted role, emits a {RoleGranted} event. Requirements: - the caller must have role's admin role. May emit a {RoleGranted} event.

Parameters

hasRole

function hasRole(bytes32 role, address account) external view returns (bool)

Returns true if account has been granted role.

Parameters

Returns

isApprovedForAll

function isApprovedForAll(address account, address operator) external view returns (bool)

See {IERC1155-isApprovedForAll}.

Parameters

Returns

mint

function mint(address account, uint256 id, uint256 amount, bytes data) external nonpayable

Parameters

mintBatch

function mintBatch(address to, uint256[] ids, uint256[] amounts, bytes data) external nonpayable

Parameters

renounceRole

function renounceRole(bytes32 role, address account) external nonpayable

Revokes role from the calling account. Roles are often managed via {grantRole} and {revokeRole}: this function's purpose is to provide a mechanism for accounts to lose their privileges if they are compromised (such as when a trusted device is misplaced). If the calling account had been revoked role, emits a {RoleRevoked} event. Requirements: - the caller must be account. May emit a {RoleRevoked} event.

Parameters

revokeRole

function revokeRole(bytes32 role, address account) external nonpayable

Revokes role from account. If account had been granted role, emits a {RoleRevoked} event. Requirements: - the caller must have role's admin role. May emit a {RoleRevoked} event.

Parameters

safeBatchTransferFrom

function safeBatchTransferFrom(address from, address to, uint256[] ids, uint256[] amounts, bytes data) external nonpayable

See {IERC1155-safeBatchTransferFrom}.

Parameters

safeTransferFrom

function safeTransferFrom(address from, address to, uint256 id, uint256 amount, bytes data) external nonpayable

See {IERC1155-safeTransferFrom}.

Parameters

setApprovalForAll

function setApprovalForAll(address operator, bool approved) external nonpayable

See {IERC1155-setApprovalForAll}.

Parameters

setBaseURI

function setBaseURI(string baseURI_) external nonpayable

Parameters

setContractURI

function setContractURI(string contractURI_) external nonpayable

Parameters

setTokenURI

function setTokenURI(uint256 tokenId, string tokenURI_) external nonpayable

Parameters

supportsInterface

function supportsInterface(bytes4 interfaceId) external view returns (bool)

Parameters

Returns

uri

function uri(uint256 tokenId) external view returns (string)

Parameters

Returns

Events

ApprovalForAll

event ApprovalForAll(address indexed account, address indexed operator, bool approved)

Emitted when account grants or revokes permission to operator to transfer their tokens, according to approved.

Parameters

RoleAdminChanged

event RoleAdminChanged(bytes32 indexed role, bytes32 indexed previousAdminRole, bytes32 indexed newAdminRole)

Emitted when newAdminRole is set as role's admin role, replacing previousAdminRole DEFAULT_ADMIN_ROLE is the starting admin for all roles, despite {RoleAdminChanged} not being emitted signaling this. _Available since v3.1._

Parameters

RoleGranted

event RoleGranted(bytes32 indexed role, address indexed account, address indexed sender)

Emitted when account is granted role. sender is the account that originated the contract call, an admin role bearer except when using {AccessControl-_setupRole}.

Parameters

RoleRevoked

event RoleRevoked(bytes32 indexed role, address indexed account, address indexed sender)

Emitted when account is revoked role. sender is the account that originated the contract call: - if using revokeRole, it is the admin role bearer - if using renounceRole, it is the role bearer (i.e. account)

Parameters

TransferBatch

event TransferBatch(address indexed operator, address indexed from, address indexed to, uint256[] ids, uint256[] values)

Equivalent to multiple {TransferSingle} events, where operator, from and to are the same for all transfers.

Parameters

TransferSingle

event TransferSingle(address indexed operator, address indexed from, address indexed to, uint256 id, uint256 value)

Emitted when value tokens of token type id are transferred from from to to by operator.

Parameters

URI

event URI(string value, uint256 indexed id)

Emitted when the URI for token type id changes to value, if it is a non-programmatic URI. If an {URI} event was emitted for id, the standard https://eips.ethereum.org/EIPS/eip-1155#metadata-extensions[guarantees] that value will equal the value returned by {IERC1155MetadataURI-uri}.
