# IAlgebraVirtualPool

The interface for the virtual pool

*Developer note: Used to calculate active liquidity in farmings*

## Functions

### crossTo

`function crossTo(int24 targetTick, bool zeroToOne) external returns (bool success)` external

*Developer note: This function is called by the main pool if an initialized ticks are crossed by swap. If any one of crossed ticks is also initialized in a virtual pool it should be crossed too*
