function getPair(address tokenA, address tokenB) external view returns (address pair);Address for
tokenA and address for tokenB return address of pair contract (where one exists).tokenA and tokenB order is interchangeable.Returns
0x0000000000000000000000000000000000000000 as address where no pair exists.function allPairs(uint) external view returns (address pair);Returns the address of the
nth pair (0-indexed) created through the Factory contract.Returns
0x0000000000000000000000000000000000000000 where pair has not yet been created.Begins at
0 for first created pair.function allPairsLength() external view returns (uint);Displays the current number of pairs created through the Factory contract as an integer.
function feeTo() external view returns (address);The address to where non-LP-holder fees are sent.
function feeToSetter() external view returns (address);The address with permission to set the feeTo address.
function createPair(address tokenA, address tokenB) external returns (address pair);
Creates a pair for
tokenA and tokenB where a pair doesn't already exist.tokenA and tokenB order is interchangeable.Emits
PairCreated (see Events).Sets address for
feeTo.Sets address for permission to adjust
feeTo.event PairCreated(address indexed token0, address indexed token1, address pair, uint);Emitted whenever a
createPair creates a new pair.token0 will appear before token1 in sort order.The final
uint log value will be 1 for the first pair created, 2 for the second, etc.import '@uniswap/v2-core/contracts/interfaces/IPancakeFactory.sol';
