Functions

constructor

constructor(address _factory, address _WNativeToken, address _tokenDescriptor_, address _poolDeployer) public public

positions

function positions(uint256 tokenId) external view returns (uint88 nonce, address operator, address token0, address token1, int24 tickLower, int24 tickUpper, uint128 liquidity, uint256 feeGrowthInside0LastX128, uint256 feeGrowthInside1LastX128, uint128 tokensOwed0, uint128 tokensOwed1) view external

Returns the position information associated with a given token ID. Developer note: Throws if the token ID is not valid.

Returns:

mint

function mint(struct INonfungiblePositionManager.MintParams params) external payable returns (uint256 tokenId, uint128 liquidity, uint256 amount0, uint256 amount1) payable external

Creates a new position wrapped in a NFT Developer note: Call this when the pool does exist and is initialized. Note that if the pool is created but not initialized a method does not exist, i.e. the pool is assumed to be initialized.

Returns:

tokenURI

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

Returns:

baseURI

function baseURI() public pure returns (string) pure public

Returns:

increaseLiquidity

function increaseLiquidity(struct INonfungiblePositionManager.IncreaseLiquidityParams params) external payable returns (uint128 liquidity, uint256 amount0, uint256 amount1) payable external

Increases the amount of liquidity in a position, with tokens paid by the `msg.sender`

Collects up to a maximum amount of fees owed to a specific position to the recipient

Returns:

burn

function burn(uint256 tokenId) external payable payable external

setFarmingCenter

function setFarmingCenter(address newFarmingCenter) external external

Changes address of farmingCenter Developer note: can be called only by factory owner or NONFUNGIBLE_POSITION_MANAGER_ADMINISTRATOR_ROLE
