Basic ERC721 implementation
_ERC721Data
Copy struct MintableERC721Data _ERC721Data onlyPoolAdmin
Copy modifier onlyPoolAdmin () Only pool admin can call functions marked by this modifier.
onlyPool
Only pool can call functions marked by this modifier.
_addressesProvider
Copy contract IPoolAddressesProvider _addressesProvider UserState - additionalData is a flexible field. PTokens and VariableDebtTokens use this field store the index of the user's last supply/withdrawal/borrow/repayment. StableDebtTokens use this field to store the user's stable rate.
POOL
ATOMIC_PRICING
_underlyingAsset
Copy address _underlyingAsset constructor
Copy constructor (contract IPool pool , string name_ , string symbol_ , bool atomic_pricing) internal Constructor.
Parameters
name
Copy function name () public view returns ( string ) Returns the token collection name.
symbol
Copy function symbol () external view returns ( string ) Returns the token collection symbol.
balanceOf
Copy function balanceOf ( address account) public view virtual returns ( uint256 ) getIncentivesController
Copy function getIncentivesController () external view virtual returns (contract IRewardController ) Returns the address of the Incentives Controller contract
Return Values
setIncentivesController
Copy function setIncentivesController (contract IRewardController controller) external Sets a new Incentives Controller
Parameters
setBalanceLimit
Copy function setBalanceLimit ( uint64 limit) external Sets new Balance Limit
Parameters
_setName
Copy function _setName ( string newName) internal Update the name of the token
Parameters
_setSymbol
Copy function _setSymbol ( string newSymbol) internal Update the symbol for the token
Parameters
ownerOf
Copy function ownerOf ( uint256 tokenId) public view virtual returns ( address ) See {IERC721-ownerOf}.
tokenURI
Copy function tokenURI ( uint256 ) external view virtual returns ( string ) See {IERC721Metadata-tokenURI}.
approve
Copy function approve ( address to , uint256 tokenId) external virtual See {IERC721-approve}.
getApproved
Copy function getApproved ( uint256 tokenId) public view virtual returns ( address ) See {IERC721-getApproved}.
setApprovalForAll
Copy function setApprovalForAll ( address operator , bool approved) external virtual See {IERC721-setApprovalForAll}.
isApprovedForAll
Copy function isApprovedForAll ( address owner , address operator) public view virtual returns ( bool ) See {IERC721-isApprovedForAll}.
transferFrom
Copy function transferFrom ( address from , address to , uint256 tokenId) external virtual See {IERC721-transferFrom}.
safeTransferFrom
Copy function safeTransferFrom ( address from , address to , uint256 tokenId) external virtual See {IERC721-safeTransferFrom}.
safeTransferFrom
Copy function safeTransferFrom ( address from , address to , uint256 tokenId , bytes _data ) external virtual See {IERC721-safeTransferFrom}.
_safeTransferFrom
Copy function _safeTransferFrom ( address from , address to , uint256 tokenId , bytes _data ) internal _safeTransfer
Copy function _safeTransfer ( address from , address to , uint256 tokenId , bytes ) internal virtual _Safely transfers tokenId token from from to to, checking first that contract recipients are aware of the ERC721 protocol to prevent tokens from being forever locked.
_data is additional data, it has no specified format and it is sent in call to to.
This internal function is equivalent to {safeTransferFrom}, and can be used to e.g. implement alternative mechanisms to perform token transfer, such as signature-based.
Requirements:
from cannot be the zero address.
to cannot be the zero address.
tokenId token must exist and be owned by from.
Emits a {Transfer} event._
_exists
Copy function _exists ( uint256 tokenId) internal view virtual returns ( bool ) _Returns whether tokenId exists.
Tokens can be managed by their owner or approved accounts via {approve} or {setApprovalForAll}.
Tokens start existing when they are minted (_mint), and stop existing when they are burned (_burn)._
_isApprovedOrOwner
Copy function _isApprovedOrOwner ( address spender , uint256 tokenId) internal view virtual returns ( bool ) _Returns whether spender is allowed to manage tokenId.
Requirements:
_mintMultiple
Copy function _mintMultiple(address to, struct DataTypes.ERC721SupplyParams[] tokenData) internal virtual returns (uint64 oldCollateralizedBalance, uint64 newCollateralizedBalance) _burnMultiple
Copy function _burnMultiple(address user, uint256[] tokenIds) internal virtual returns (uint64 oldCollateralizedBalance, uint64 newCollateralizedBalance) _transfer
Copy function _transfer ( address from , address to , uint256 tokenId) internal virtual _Transfers tokenId from from to to. As opposed to {transferFrom}, this imposes no restrictions on msg.sender.
Requirements:
to cannot be the zero address.
tokenId token must be owned by from.
Emits a {Transfer} event._
_transferCollateralizable
Copy function _transferCollateralizable(address from, address to, uint256 tokenId) internal virtual returns (bool isUsedAsCollateral_) update collateral information on transfer
collateralizedBalanceOf
Copy function collateralizedBalanceOf ( address account) public view virtual returns ( uint256 ) get the collateralized balance of a specific user
setIsUsedAsCollateral
Copy function setIsUsedAsCollateral ( uint256 tokenId , bool useAsCollateral , address sender) external virtual returns ( bool ) changes the collateral state/config of a token
Return Values
batchSetIsUsedAsCollateral
Copy function batchSetIsUsedAsCollateral(uint256[] tokenIds, bool useAsCollateral, address sender) external virtual returns (uint256 oldCollateralizedBalance, uint256 newCollateralizedBalance) the ids of the token want to change the collateral state
Return Values
isUsedAsCollateral
Copy function isUsedAsCollateral ( uint256 tokenId) external view returns ( bool ) get the the collateral configuration of a specific token
isAuctioned
Copy function isAuctioned ( uint256 tokenId) external view returns ( bool ) get the auction configuration of a specific token
startAuction
Copy function startAuction ( uint256 tokenId) external virtual start auction
endAuction
Copy function endAuction ( uint256 tokenId) external virtual end auction
getAuctionData
Copy function getAuctionData ( uint256 tokenId) external view returns (struct DataTypes . Auction auction) get auction data
supportsInterface
Copy function supportsInterface ( bytes4 interfaceId) external view virtual returns ( bool ) See {IERC165-supportsInterface}.
tokenOfOwnerByIndex
Copy function tokenOfOwnerByIndex ( address owner , uint256 index) external view virtual returns ( uint256 ) See {IERC721Enumerable-tokenOfOwnerByIndex}.
totalSupply
Copy function totalSupply () public view virtual returns ( uint256 ) See {IERC721Enumerable-totalSupply}.
