# Module

[Git Source](https://github.com/EntreDevelopers-Lab-Inc/Mezz-Companies/blob/f7a3e84e3dd5bb33c4bd7f77283983f9e8ba20b2/src/core/modules/Module.sol)

**Inherits:** Initializable, ERC165Upgradeable, TeamControlled, IModule

**Author:** Daniel Yamagata & Naveen Ailawadi

A base contract for modules, which are 'children' of departments and treasuries with bespoke logic and spending capabilities

\*Modules should be deployed as proxies. If ERC1967 proxies, their storage layout should use EIP7201 storage slots Reference:

* [EIP7201](https://eips.ethereum.org/EIPS/eip-7201)
* [ERC1967 Proxies](https://github.com/OpenZeppelin/openzeppelin-contracts/blob/b5a7f977d8a57b6854545522e36d91a0c11723cd/contracts/proxy/ERC1967/ERC1967Proxy.sol*)

## Functions

### constructor

```solidity
constructor();
```

### init

Initializes the state of the module. This initialization is bespoke to each module

```solidity
function init(address initTeam, bytes memory params) external virtual;
```

**Parameters**

| Name       | Type      | Description                                                                 |
| ---------- | --------- | --------------------------------------------------------------------------- |
| `initTeam` | `address` | The team that controls the module                                           |
| `params`   | `bytes`   | The abi-encoded params to be decoded and passed to the module's initializer |

### \_\_Module\_init

```solidity
function __Module_init(address initTeam) internal virtual onlyInitializing;
```

### supportsInterface

*ERC165 support*

```solidity
function supportsInterface(bytes4 interfaceId)
    public
    view
    virtual
    override(ERC165Upgradeable, IERC165)
    returns (bool);
```

### getParent

Returns the parent of 'this'. If 'this' is a department or module, returns the team that directly controls 'this'. If 'this' is the Treasury, returns the sentinel parent, which is address(0x1)

```solidity
function getParent() public view virtual returns (address);
```

**Returns**

| Name     | Type      | Description                                                                              |
| -------- | --------- | ---------------------------------------------------------------------------------------- |
| `<none>` | `address` | The parent, which is either the treasury, a department, a module, or the sentinel parent |
