Functions
getInnerSecondsPerLiquidity
function getInnerSecondsPerLiquidity(int24 bottomTick, int24 topTick) external view returns (uint160 innerSecondsSpentPerLiquidity) view external
get seconds per liquidity inside range
| Name | Type | Description |
|---|---|---|
bottomTick | int24 | |
topTick | int24 |
Returns:
| Name | Type | Description |
|---|---|---|
innerSecondsSpentPerLiquidity | uint160 |
cross
function cross(int24 nextTick, bool zeroToOne) external external
Developer note: This function is called by the main pool when an initialized tick is crossed there. If the tick is also initialized in a virtual pool it should be crossed too
| Name | Type | Description |
|---|---|---|
nextTick | int24 | The crossed tick |
zeroToOne | bool | The direction |
increaseCumulative
function increaseCumulative(uint32 currentTimestamp) external returns (enum IAlgebraVirtualPool.Status) external
Developer note: This function is called from the main pool before every swap To increase seconds per liquidity cumulative considering previous timestamp and liquidity. The liquidity is stored in a virtual pool
| Name | Type | Description |
|---|---|---|
currentTimestamp | uint32 | The timestamp of the current swap |
Returns:
| Name | Type | Description |
|---|---|---|
[0] | enum IAlgebraVirtualPool.Status | Status The status of virtual pool |
applyLiquidityDeltaToPosition
function applyLiquidityDeltaToPosition(uint32 currentTimestamp, int24 bottomTick, int24 topTick, int128 liquidityDelta, int24 currentTick) external external
Developer note: This function is called when anyone farms their liquidity. The position in a virtual pool should be changed accordingly
| Name | Type | Description |
|---|---|---|
currentTimestamp | uint32 | The timestamp of current block |
bottomTick | int24 | The bottom tick of a position |
topTick | int24 | The top tick of a position |
liquidityDelta | int128 | The amount of liquidity in a position |
currentTick | int24 | The current tick in the main pool |
