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.
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.

exactInputSingle
function exactInputSingle(struct ISwapRouter.ExactInputSingleParams params) external payable returns (uint256 amountOut) payable external
Swaps `amountIn` of one token for as much as possible of another token
params
struct ISwapRouter.ExactInputSingleParams
The parameters necessary for the swap, encoded as `ExactInputSingleParams` in calldata
Returns:
amountOut
uint256
The amount of the received token
exactInput
function exactInput(struct ISwapRouter.ExactInputParams params) external payable returns (uint256 amountOut) payable external
Swaps `amountIn` of one token for as much as possible of another along the specified path
params
struct ISwapRouter.ExactInputParams
The parameters necessary for the multi-hop swap, encoded as `ExactInputParams` in calldata
Returns:
amountOut
uint256
The amount of the received token
exactInputSingleSupportingFeeOnTransferTokens
function exactInputSingleSupportingFeeOnTransferTokens(struct ISwapRouter.ExactInputSingleParams params) external returns (uint256 amountOut) external
Swaps `amountIn` of one token for as much as possible of another along the specified path Developer note: Unlike standard swaps, handles transferring from user before the actual swap.
