SafeCallback

Inherits: ImmutableState, IUnlockCallback

A contract that only allows the v4 PoolManager to call the unlockCallback

Functions

constructor(IPoolManager _poolManager) ImmutableState(_poolManager);

Called by the pool manager on msg.sender when the manager is unlocked

We force the onlyPoolManager modifier by exposing a virtual function after the onlyPoolManager check.

function unlockCallback(bytes calldata data) external onlyPoolManager returns (bytes memory);

Parameters

Name	Type	Description
`data`	`bytes`	The data that was passed to the call to unlock

Returns

Name	Type	Description
`<none>`	`bytes`	Any data that you want to be returned from the unlock call

to be implemented by the child contract, to safely guarantee the logic is only executed by the PoolManager

function _unlockCallback(bytes calldata data) internal virtual returns (bytes memory);
