## Functions

### getConditionId

```solidity
function getConditionId(address oracle, bytes32 questionId, uint256 outcomeSlotCount) internal pure returns (bytes32)
```

*Constructs a condition ID from an oracle, a question ID, and the outcome slot count for the question.*

**Parameters**

| Name             | Type    | Description                                                                               |
| ---------------- | ------- | ----------------------------------------------------------------------------------------- |
| oracle           | address | The account assigned to report the result for the prepared condition.                     |
| questionId       | bytes32 | An identifier for the question to be answered by the oracle.                              |
| outcomeSlotCount | uint256 | The number of outcome slots which should be used for this condition. Must not exceed 256. |

### getCollectionId

```solidity
function getCollectionId(bytes32 parentCollectionId, bytes32 conditionId, uint256 indexSet) internal view returns (bytes32)
```

*Constructs an outcome collection ID from a parent collection and an outcome collection.*

**Parameters**

| Name               | Type    | Description                                                                           |
| ------------------ | ------- | ------------------------------------------------------------------------------------- |
| parentCollectionId | bytes32 | Collection ID of the parent outcome collection, or bytes32(0) if there's no parent.   |
| conditionId        | bytes32 | Condition ID of the outcome collection to combine with the parent outcome collection. |
| indexSet           | uint256 | Index set of the outcome collection to combine with the parent outcome collection.    |

### getPositionId

```solidity
function getPositionId(contract IERC20 collateralToken, bytes32 collectionId) internal pure returns (uint256)
```

*Constructs a position ID from a collateral token and an outcome collection. These IDs are used as the ERC-1155 ID for this contract.*

**Parameters**

| Name            | Type            | Description                                                 |
| --------------- | --------------- | ----------------------------------------------------------- |
| collateralToken | contract IERC20 | Collateral token which backs the position.                  |
| collectionId    | bytes32         | ID of the outcome collection associated with this position. |
