Functions

algebraSwapCallback

function algebraSwapCallback(int256 amount0Delta, int256 amount1Delta, bytes data) external external

Called to `msg.sender` after executing a swap via IAlgebraPool#swap. Developer note: In the implementation you must pay the pool tokens owed for the swap. The caller of this method must be checked to be a AlgebraPool deployed by the canonical AlgebraFactory. amount0Delta and amount1Delta can both be 0 if no tokens were swapped.

Name	Type	Description
amount0Delta	int256	The amount of token0 that was sent (negative) or must be received (positive) by the pool by
the end of the swap. If positive, the callback must send that amount of token0 to the pool.
amount1Delta	int256	The amount of token1 that was sent (negative) or must be received (positive) by the pool by
the end of the swap. If positive, the callback must send that amount of token1 to the pool.
data	bytes	Any data passed through by the caller via the IAlgebraPoolActions#swap call
