# PoolTicksCounter

### Functions <a href="#functions" id="functions"></a>

#### countInitializedTicksCrossed <a href="#countinitializedtickscrossed" id="countinitializedtickscrossed"></a>

*This function counts the number of initialized ticks that would incur a gas cost between tickBefore and tickAfter. When tickBefore and/or tickAfter themselves are initialized, the logic over whether we should count them depends on the direction of the swap. If we are swapping upwards (tickAfter > tickBefore) we don't want to count tickBefore but we do want to count tickAfter. The opposite is true if we are swapping downwards.*

```solidity
function countInitializedTicksCrossed(IDragonswapV2Pool self, int24 tickBefore, int24 tickAfter)
    internal
    view
    returns (uint32 initializedTicksCrossed);
```

#### countOneBits <a href="#countonebits" id="countonebits"></a>

```solidity
function countOneBits(uint256 x) private pure returns (uint16);
```
