[Git Source](https://github.com/thrackle-io/liquidity-altbc/blob/a089af3d235b9241cf0ed6c700a259b616853515/src/common/FactoryDeployHelper.sol)

## Functions

### setPoolByteCode

the setByteCode function is expected to receive only bytes as its only parameter

the makeByteCodeImmutable function is expected to receive no parameters

*helper function to send the byte code in chunks to the factory and then make it immutable*

```solidity theme={null}
function setPoolByteCode(
    address factoryAddress,
    bytes memory bytecode,
    uint256 chunks,
    bytes4 setByteCodeSelector,
    bytes4 makeImmutableSelector
) internal;
```

**Parameters**

| Name                    | Type      | Description                                       |
| ----------------------- | --------- | ------------------------------------------------- |
| `factoryAddress`        | `address` | address of the factory where to set the byte code |
| `bytecode`              | `bytes`   | the full byte code to set                         |
| `chunks`                | `uint256` | number of chunks to split the byte code into      |
| `setByteCodeSelector`   | `bytes4`  | selector of the setByteCode function              |
| `makeImmutableSelector` | `bytes4`  | selector of the makeByteCodeImmutable function    |

*helper function to slice bytes arrays*

```solidity theme={null}
function slice(bytes memory _bytes, uint256 _start, uint256 _length) private pure returns (bytes memory);
```

**Parameters**

| Name      | Type      | Description              |
| --------- | --------- | ------------------------ |
| `_bytes`  | `bytes`   | the bytes array to slice |
| `_start`  | `uint256` | the starting index       |
| `_length` | `uint256` | the length of the slice  |

**Returns**

| Name     | Type    | Description                      |
| -------- | ------- | -------------------------------- |
| `<none>` | `bytes` | tempBytes the sliced bytes array |
