  newOwner - Represents the new owner of the contract.

• Upgraded

  event Upgraded(uint256 version, address implementation)

  ---

  Emitted by the `upgradeTo` function every time the implementation gets upgraded.

  Parameters:

  implementation - The new address of the upgraded implementation.

Functions

• fallback

  function (address _implementationAddress, address _ownerAddress) public

  ---

  Parameters:

  _implementationAddress - The address of the implementation. This must either be the address of an already-constructed contract, or `address(0)`. In the latter case, the implementation can be set later using the `upgradeTo` function.

  _ownerAddress - The owner of the contract. If set to `address(0)`, then `msg.sender` will be used instead.
