# IRamsesV3PoolOwnerActions

Contains pool methods that may only be called by the factory owner

## Functions

### setFeeProtocol

```solidity theme={null}
  function setFeeProtocol(
  ) external
```

Syncs the pool's protocol fee from the factory. Called by the factory when the global or pool-specific fee protocol is updated. Takes no parameters -- reads the fee directly from `IRamsesV3Factory.poolFeeProtocol(address(this))`.

### collectProtocol

```solidity theme={null}
  function collectProtocol(
    address recipient,
    uint128 amount0Requested,
    uint128 amount1Requested
  ) external returns (uint128 amount0, uint128 amount1)
```

Collect the protocol fee accrued to the pool

#### Parameters:

| `recipient`        | address | The address to which collected protocol fees should be sent                   |
| `amount0Requested` | uint128 | The maximum amount of token0 to send, can be 0 to collect fees in only token1 |
| `amount1Requested` | uint128 | The maximum amount of token1 to send, can be 0 to collect fees in only token0 |

#### Return Values:

| Name      | Type    | Description                          |
| :-------- | :------ | :----------------------------------- |
| `amount0` | uint128 | The protocol fee collected in token0 |

```solidity theme={null}
  function setFee(
    uint24 _fee
  ) external
