VersionedInitializable

Git Source

Author: Aave, inspired by the OpenZeppelin Initializable contract

Helper contract to implement initializer functions. To use it, replace the constructor with a function that has the initializer modifier.

WARNING: Unlike constructors, initializer functions must be manually invoked. This applies both to deploying an Initializable contract, as well as extending an Initializable contract via inheritance. WARNING: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or ensure that all initializers are idempotent, because this is not dealt with automatically as with constructors.

Functions

initializer

Modifier to use in the initializer function of a contract.

modifier initializer();

onlyInitializing

Modifier to use when a function is restricted to the initialization phase.

modifier onlyInitializing();

getRevision

Returns the revision number of the contract

Needs to be defined in the inherited class as a constant.

function getRevision() public pure virtual returns (uint256);

Returns

Name	Type	Description
<none>	uint256	The revision number

isConstructor

Returns true if and only if the function is running in the constructor

function isConstructor() private view returns (bool);

Returns

Name	Type	Description
<none>	bool	True if the function is running in the constructor

_getInitializableStorage

function _getInitializableStorage() private pure returns (VersionedInitializableStorage storage $);

_getLastInitializedRevision

function _getLastInitializedRevision() internal view returns (uint256);

_getInitializing

function _getInitializing() internal view returns (bool);

Structs

VersionedInitializableStorage

Indicates that the contract has been initialized.

struct VersionedInitializableStorage {
    uint256 lastInitializedRevision;
    bool initializing;
