Ownable
Inherits: Context
Contract module which provides a basic access control mechanism, where
there is an account (an owner) that can be granted exclusive access to
specific functions.
By default, the owner account will be the one that deploys the contract. This
can later be changed with {transferOwnership}.
This module is used through inheritance. It will make available the modifier
onlyOwner
, which can be applied to your functions to restrict their use to
the owner.
State Variables
_owner
address private _owner;
Functions
constructor
Initializes the contract setting the deployer as the initial owner.
constructor();
owner
Returns the address of the current owner.
function owner() public view virtual returns (address);
onlyOwner
Throws if called by any account other than the owner.
modifier onlyOwner();
renounceOwnership
Leaves the contract without owner. It will not be possible to call
onlyOwner
functions anymore. Can only be called by the current owner.
NOTE: Renouncing ownership will leave the contract without an owner,
thereby removing any functionality that is only available to the owner.
function renounceOwnership() public virtual onlyOwner;
transferOwnership
Transfers ownership of the contract to a new account (newOwner
).
Can only be called by the current owner.
function transferOwnership(address newOwner) public virtual onlyOwner;
_setOwner
function _setOwner(address newOwner) private;
Events
OwnershipTransferred
event OwnershipTransferred(address indexed previousOwner, address indexed newOwner);
