| /** | |
| * @dev Contract module that allows children to implement role-based access | |
| * control mechanisms. This is a lightweight version that doesn't allow enumerating role | |
| * members except through off-chain means by accessing the contract event logs. Some | |
| * applications may benefit from on-chain enumerability, for those cases see | |
| * {AccessControlEnumerable}. | |
| * | |
| * Roles are referred to by their `bytes32` identifier. These should be exposed | |
| * in the external API and be unique. The best way to achieve this is by | |
| * using `public constant` hash digests: | |
| * | |
| * ``` | |
| * bytes32 public constant MY_ROLE = keccak256("MY_ROLE"); | |
| * ``` | |
| * | |
| * Roles can be used to represent a set of permissions. To restrict access to a | |
| * function call, use {hasRole}: | |
| * | |
| * ``` | |
| * function foo() public { | |
| * require(hasRole(MY_ROLE, msg.sender)); | |
| * ... | |
| * } | |
| * ``` | |
| * | |
| * Roles can be granted and revoked dynamically via the {grantRole} and | |
| * {revokeRole} functions. Each role has an associated admin role, and only | |
| * accounts that have a role's admin role can call {grantRole} and {revokeRole}. | |
| * | |
| * By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means | |
| * that only accounts with this role will be able to grant or revoke other | |
| * roles. More complex role relationships can be created by using | |
| * {_setRoleAdmin}. | |
| * | |
| * WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to | |
| * grant and revoke this role. Extra precautions should be taken to secure | |
| * accounts that have been granted it. | |
