Read functions

getPair

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.

allPairs

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.

allPairsLength

function allPairsLength() external view returns (uint);

Displays the current number of pairs created through the Factory contract as an integer.

feeTo

function feeTo() external view returns (address);

The address to where non-LP-holder fees are sent.

feeToSetter

function feeToSetter() external view returns (address);

The address with permission to set the feeTo address.

Write functions

createPair

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).

setFeeTo

Sets address for feeTo.

setFeeToSetter

Sets address for permission to adjust feeTo.

Events

PairCreated

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.
