A contract that constructs a pool must implement this to pass arguments to the pool

This is used to avoid having constructor arguments in the pool contract, which results in the init code hash of the pool being constant allowing the CREATE2 address of the pool to be cheaply computed on-chain



  function parameters(
) external view returns (address factory, address token0, address token1, uint24 fee, int24 tickSpacing)

Get the parameters to be used in constructing the pool, set transiently during pool creation.

Return Values :

factory addressThe factory address
token0addressThe first token of the pool by address sort order
token1addressThe second token of the pool by address sort order
fee uint24The fee collected upon every swap in the pool, denominated in hundredths of a bip
tickSpacingint24The minimum number of ticks between initialized ticks
