onlyRoleManager(uint256 roleId) modifier

Reverts unless the caller is a member of the manager role for the specified roleId.

onlyExclusive(uint256 roleId) modifier

Reverts unless the roleId represents an initialized, exclusive roleId.

onlyShared(uint256 roleId) modifier

Reverts unless the roleId represents an initialized, shared roleId.

onlyValidRole(uint256 roleId) modifier

Reverts if roleId is not initialized.

onlyInvalidRole(uint256 roleId) modifier

Reverts if roleId is initialized.

_transfer(address from, address to, uint256 value) internal

_mint(address account, uint256 value) internal

_burn(address account, uint256 value) internal

snapshot() → uint256 public

balanceOfAt(address account, uint256 snapshotId) → uint256 public

totalSupplyAt(uint256 snapshotId) → uint256 public

mint(address recipient, uint256 value) → bool external

Mints value tokens to recipient, returning true on success.

burn(uint256 value) external

Burns value tokens owned by msg.sender.

holdsRole(uint256 roleId, address memberToCheck) → bool public

Whether memberToCheck is a member of roleId.

Reverts if roleId does not correspond to an initialized role.

resetMember(uint256 roleId, address newMember) public

Changes the exclusive role holder of roleId to newMember.

Reverts if the caller is not a member of the managing role for roleId or if roleId is not an initialized, exclusive role.

getMember(uint256 roleId) → address public

Gets the current holder of the exclusive role, roleId.

Reverts if roleId does not represent an initialized, exclusive role.

addMember(uint256 roleId, address newMember) public

Adds newMember to the shared role, roleId.

Reverts if roleId does not represent an initialized, shared role or if the caller is not a member of the managing role for roleId.

removeMember(uint256 roleId, address memberToRemove) public

Removes memberToRemove from the shared role, roleId.

Reverts if roleId does not represent an initialized, shared role or if the caller is not a member of the managing role for roleId.

_createSharedRole(uint256 roleId, uint256 managingRoleId, address[] initialMembers) internal

Internal method to initialize a shared role, roleId, which will be managed by managingRoleId. initialMembers will be immediately added to the role.

Should be called by derived contracts, usually at construction time. Will revert if the role is already initialized.

_createExclusiveRole(uint256 roleId, uint256 managingRoleId, address initialMember) internal

Internal method to initialize a exclusive role, roleId, which will be managed by managingRoleId. initialMembers will be immediately added to the role.

Should be called by derived contracts, usually at construction time. Will revert if the role is already initialized.

totalSupply() → uint256 public

See {IERC20-totalSupply}.

balanceOf(address account) → uint256 public

See {IERC20-balanceOf}.

transfer(address recipient, uint256 amount) → bool public

See {IERC20-transfer}.

Requirements:

  • recipient cannot be the zero address.

  • the caller must have a balance of at least amount.

allowance(address owner, address spender) → uint256 public

See {IERC20-allowance}.

approve(address spender, uint256 amount) → bool public

See {IERC20-approve}.

Requirements:

  • spender cannot be the zero address.

transferFrom(address sender, address recipient, uint256 amount) → bool public

See {IERC20-transferFrom}.

Emits an {Approval} event indicating the updated allowance. This is not required by the EIP. See the note at the beginning of {ERC20};

Requirements: - sender and recipient cannot be the zero address. - sender must have a balance of at least amount. - the caller must have allowance for sender’s tokens of at least `amount.

increaseAllowance(address spender, uint256 addedValue) → bool public

Atomically increases the allowance granted to spender by the caller.

This is an alternative to {approve} that can be used as a mitigation for problems described in {IERC20-approve}.

Emits an {Approval} event indicating the updated allowance.

Requirements:

  • spender cannot be the zero address.

decreaseAllowance(address spender, uint256 subtractedValue) → bool public

Atomically decreases the allowance granted to spender by the caller.

This is an alternative to {approve} that can be used as a mitigation for problems described in {IERC20-approve}.

Emits an {Approval} event indicating the updated allowance.

Requirements:

  • spender cannot be the zero address.

  • spender must have allowance for the caller of at least subtractedValue.

_approve(address owner, address spender, uint256 amount) internal

Sets amount as the allowance of spender over the `owner`s tokens.

This is internal function is equivalent to approve, and can be used to e.g. set automatic allowances for certain subsystems, etc.

Emits an {Approval} event.

Requirements:

  • owner cannot be the zero address.

  • spender cannot be the zero address.

_burnFrom(address account, uint256 amount) internal

Destroys amount tokens from account.amount is then deducted from the caller’s allowance.

See _burn and {_approve}.

_beforeTokenTransfer(address from, address to, uint256 amount) internal

Hook that is called before any transfer of tokens. This includes minting and burning.

Calling conditions:

  • when from and to are both non-zero, amount of from’s tokens will be to transferred to `to.

  • when from is zero, amount tokens will be minted for to.

  • when to is zero, amount of `from’s tokens will be burned.

  • from and to are never both zero.

Snapshot(uint256 id) event

Transfer(address from, address to, uint256 value) event

Emitted when value tokens are moved from one account (from) to another (to).

Note that value may be zero.

Approval(address owner, address spender, uint256 value) event

Emitted when the allowance of a spender for an owner is set by a call to {approve}. value is the new allowance.
