Methods
approve
function approve(address to, uint256 positionId) external nonpayableGives permission to to to transfer positionId token to another account. The approval is cleared when the token is transferred. Only a single account can be approved at a time, so approving the zero address clears previous approvals. Requirements: - The caller must own the token or be an approved operator. - positionId must exist. Emits an {Approval} event.
balanceOf
function balanceOf(address owner) external view returns (uint256 balance)Returns the number of position NFTs in owner's account.
burn
function burn(uint256 positionId, uint128 amount, address recipient, uint256 minimumOut0, uint256 minimumOut1, bool unwrap) external nonpayable returns (uint256 token0Amount, uint256 token1Amount)burn liquidity ( if burn all liquidity, delete position Id )

ownerOf
function ownerOf(uint256 positionId) external view returns (address owner)Returns the owner of the positionId token. Requirements: - positionId must exist.

safeTransferFrom
function safeTransferFrom(address from, address to, uint256 tokenId) external nonpayableSafely 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. Requirements: - from cannot be the zero address. - to cannot be the zero address. - tokenId token must exist and be owned by from. - If the caller is not from, it must be have been allowed to move this token by either {approve} or {setApprovalForAll}. - If to refers to a smart contract, it must implement {IERC721Receiver-onERC721Received}, which is called upon a safe transfer. Emits a {Transfer} event.
safeTransferFrom
function safeTransferFrom(address from, address to, uint256 tokenId, bytes data) external nonpayableSafely transfers tokenId token from from to to. Requirements: - from cannot be the zero address. - to cannot be the zero address. - tokenId token must exist and be owned by from. - If the caller is not from, it must be approved to move this token by either {approve} or {setApprovalForAll}. - If to refers to a smart contract, it must implement {IERC721Receiver-onERC721Received}, which is called upon a safe transfer. Emits a {Transfer} event.
setApprovalForAll
function setApprovalForAll(address operator, bool _approved) external nonpayableApprove or remove operator as an operator for the caller. Operators can call {transferFrom} or {safeTransferFrom} for any token owned by the caller. Requirements: - The operator cannot be the caller. Emits an {ApprovalForAll} event.
supportsInterface
function supportsInterface(bytes4 interfaceId) external view returns (bool)Returns true if this contract implements the interface defined by interfaceId. See the corresponding https://eips.ethereum.org/EIPS/eip-165#how-interfaces-are-identified[EIP section] to learn more about how these ids are created. This function call must use less than 30 000 gas.
tokenByIndex
function tokenByIndex(uint256 index) external view returns (uint256)Returns a token ID at a given index of all the tokens stored by the contract. Use along with {totalSupply} to enumerate all tokens.
tokenOfOwnerByIndex
function tokenOfOwnerByIndex(address owner, uint256 index) external view returns (uint256)Returns a token ID owned by owner at a given index of its token list. Use along with {balanceOf} to enumerate all of owner's tokens.
totalSupply
function totalSupply() external view returns (uint256)Returns the total amount of tokens stored by the contract.
transferFrom
function transferFrom(address from, address to, uint256 tokenId) external nonpayableTransfers tokenId token from from to to. WARNING: Usage of this method is discouraged, use {safeTransferFrom} whenever possible. Requirements: - from cannot be the zero address. - to cannot be the zero address. - tokenId token must be owned by from. - If the caller is not from, it must be approved to move this token by either {approve} or {setApprovalForAll}. Emits a {Transfer} event.
