tokenIdsOfOwner

function tokenIdsOfOwner(address _owner) external view returns (uint256[] tokenIds_)

totalSupply

function totalSupply() external view returns (uint256)

tokenByIndex

function tokenByIndex(uint256 _index) external view returns (uint256 tokenId_)

Enumerate valid NFTs

Throws if _index >= totalSupply().

Parameters

Name	Type	Description
_index	uint256	A counter less than totalSupply()

Return Values

Name	Type	Description
tokenId_	uint256	The token identifier for the _indexth NFT, (sort order not specified)

balanceOf

function balanceOf(address _owner) external view returns (uint256 balance_)

Count all NFTs assigned to an owner

NFTs assigned to the zero address are considered invalid, and this. function throws for queries about the zero address.

Parameters

Name	Type	Description
_owner	address	An address for whom to query the balance

Return Values

Name	Type	Description
balance_	uint256	The number of NFTs owned by _owner, possibly zero

ownerOf

function ownerOf(uint256 _tokenId) external view returns (address owner_)

Find the owner of an NFT

NFTs assigned to zero address are considered invalid, and queries about them do throw.

Parameters

Name	Type	Description
_tokenId	uint256	The identifier for an NFT

Return Values

Name	Type	Description
owner_	address	The address of the owner of the NFT

getApproved

function getApproved(uint256 _tokenId) external view returns (address approved_)

Get the approved address for a single NFT

Throws if _tokenId is not a valid NFT.

Parameters

Name	Type	Description
_tokenId	uint256	The NFT to find the approved address for

Return Values

Name	Type	Description
approved_	address	The approved address for this NFT, or the zero address if there is none

isApprovedForAll

function isApprovedForAll(address _owner, address _operator) external view returns (bool approved_)

Query if an address is an authorized operator for another address

Parameters

Name	Type	Description
_owner	address	The address that owns the NFTs
_operator	address	The address that acts on behalf of the owner

Return Values

Name	Type	Description

safeTransferFrom

function safeTransferFrom(address _from, address _to, uint256 _tokenId, bytes _data) public

Transfers the ownership of an NFT from one address to another address

Throws unless msg.sender is the current owner, an authorized operator, or the approved address for this NFT. Throws if _from is not the current owner. Throws if _to is the zero address. Throws if _tokenId is not a valid NFT. When transfer is complete, this function checks if _to is a smart contract (code size > 0). If so, it calls onERC721Received on _to and throws if the return value is not bytes4(keccak256("onERC721Received(address,address,uint256,bytes)")).

Parameters

Name	Type	Description
_from	address	The current owner of the NFT
_to	address	The new owner
_tokenId	uint256	The NFT to transfer
_data	bytes	Additional data with no specified format, sent in call to _to

safeTransferFrom

function safeTransferFrom(address _from, address _to, uint256 _tokenId) external

Transfers the ownership of an NFT from one address to another address

This works identically to the other function with an extra data parameter, except this function just sets data to "".

Parameters

Name	Type	Description
_from	address	The current owner of the NFT
_to	address	The new owner
_tokenId	uint256	The NFT to transfer

transferFrom

function transferFrom(address _from, address _to, uint256 _tokenId) external

Transfer ownership of an NFT -- THE CALLER IS RESPONSIBLE TO CONFIRM THAT _to IS CAPABLE OF RECEIVING NFTS OR ELSE THEY MAY BE PERMANENTLY LOST

Throws unless msg.sender is the current owner, an authorized operator, or the approved address for this NFT. Throws if _from is not the current owner. Throws if _to is the zero address. Throws if _tokenId is not a valid NFT.

Parameters

Name	Type	Description

_to	address	The new owner
_tokenId	uint256	The NFT to transfer

approve

function approve(address _approved, uint256 _tokenId) external

Change or reaffirm the approved address for an NFT

The zero address indicates there is no approved address. Throws unless msg.sender is the current NFT owner, or an authorized operator of the current owner.

Parameters

Name	Type	Description
_approved	address	The new approved NFT controller
_tokenId	uint256	The NFT to approve

setApprovalForAll

function setApprovalForAll(address _operator, bool _approved) external

Enable or disable approval for a third party ("operator") to manage all of msg.sender's assets
