BBStorage¶

Contract BBStorage is Ownable

BBStorage is key-value type storage:

    mapping(bytes32 => uint256)    private uIntStorage;
    mapping(bytes32 => string)     private stringStorage;
    mapping(bytes32 => address)    private addressStorage;
    mapping(bytes32 => bytes)      private bytesStorage;
    mapping(bytes32 => bool)       private boolStorage;
    mapping(bytes32 => int256)     private intStorage;
