wNFT1155

Wrapper contract for original ERC-1155 collection contract

_owners

mapping(uint256 => address) _owners

Mapping from token ID to owner address

InvalidTokenId

error InvalidTokenId(uint256 tokenId)

Trigged when non existing tokenId is queried

Parameters

Name	Type	Description
tokenId	uint256	Token identifier

MultipleOwnersNotAllowed

error MultipleOwnersNotAllowed(uint256 tokenId)

Trigged when minting of already minted ERC-1155 token is attempted This is due to limitation of the sistem that only unique (non-fungible) tokens are supported by protocol

Parameters

Name	Type	Description
tokenId	uint256	Token identifier

initialize

function initialize(address renfter_) external

Initializer method

Parameters

Name	Type	Description
renfter_	address	renfter contract address

uri

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

balanceOf

function balanceOf(address account, uint256 id) public view virtual returns (uint256)

Please be aware that balanceOf may be invalid due to token not being moved immitiatly after rent expiration but only after token is rented again or resetOwnership is called

_See {IERC1155-balanceOf}.

Requirements:

• account cannot be the zero address._

balanceOfBatch

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

Please be aware that balanceOf may be invalid due to token not being moved immitiatly after rent expiration but only after token is rented again or resetOwnership is called

_See {IERC1155-balanceOfBatch}.

Requirements:

• accounts and ids must have the same length._

safeTransferFrom

function safeTransferFrom(address from, address to, uint256 id, uint256 amount, bytes data) public virtual

See {IERC1155-safeTransferFrom}.

safeBatchTransferFrom

function safeBatchTransferFrom(address from, address to, uint256[] ids, uint256[] amounts, bytes data) public virtual

See {IERC1155-safeBatchTransferFrom}.

adminTransfer

function adminTransfer(address to, uint256 tokenId) public virtual

Transfers tokenId from current owner to to

Parameters

Name	Type	Description
to	address	Receiver address
tokenId	uint256	Token identifier

mint

function mint(address to, uint256 tokenId, uint256 amount) external virtual

Mints new token

Parameters

Name	Type	Description
to	address	Address token is minted for
tokenId	uint256	Token identifier
amount	uint256	Amount of tokens minted

burn

function burn(uint256 tokenId, uint256 amount) external virtual

Burns token from owners account

Parameters

Name	Type	Description
tokenId	uint256	Token identifier
amount	uint256	Amount of token burnt

exists

function exists(uint256 tokenId) public view virtual returns (bool)

Checks if token with passed ID exists

Return Values

Name	Type	Description
[0]	bool	Flag determinating if token exists

ownerOf

function ownerOf(uint256 tokenId) public view virtual returns (address)

Returns owner of token with given identifier

Parameters

Name	Type	Description
tokenId	uint256	Token identifier

Return Values

Name	Type	Description
[0]	address	Owner address

_beforeTokenTransfer

function _beforeTokenTransfer(address operator, address from, address to, uint256[] ids, uint256[] amounts, bytes data) internal virtual

_afterTokenTransfer

function _afterTokenTransfer(address operator, address from, address to, uint256[] ids, uint256[] amounts, bytes data) internal virtual

_Hook that is called after any token transfer. This includes minting and burning, as well as batched variants.

The same hook is called on both single and batched variants. For single transfers, the length of the id and amount arrays will be 1.

Calling conditions (for each id and amount pair):

• When from and to are both non-zero, amount of from's tokens of token type id will be transferred to to.

• When from is zero, amount tokens of token type id will be minted for to.

• when to is zero, amount of from's tokens of token type id will be burned.

• from and to are never both zero.

• ids and amounts have the same, non-zero length.
