FungibleFractionsWithTransferCallbackDO

Data Object that extends the FungibleFractionsDO functionality with transfer callback handlers

This contract extends the FungibleFractionsDO contract with the ability to register and unregister transfer callback handlers that will be called after fungible fractions transfers are performed (mint, burn, transferFrom and their batch variants) NOTE: This contract does not emit register and unregister events, it is expected that the DataManager contract will emit the events for register and unregister operations

ZeroAddressHandler

error ZeroAddressHandler()

Error thrown when the handler is the zero address

HandlerAlreadyRegistered

error HandlerAlreadyRegistered()

Error thrown when handler couldn't be added.

HandlerNotRemoved

error HandlerNotRemoved()

Error thrown when handler couldn't be removed.

DpData2

Data structure for storing transfer callback handlers

Parameters

Name	Type	Description

struct DpData2 {
  mapping(uint256 => struct EnumerableSet.AddressSet) singleIdHandlers;
  struct EnumerableSet.AddressSet allIdHandlers;
}

_dispatchWrite

function _dispatchWrite(DataPoint dp, bytes4 operation, bytes data) internal virtual returns (bytes)

_registerSingleIdFungibleFractionTransferCallback

function _registerSingleIdFungibleFractionTransferCallback(DataPoint dp, uint256 id, address handler) internal virtual

Function used to register a callback for a single id token transfer

Parameters

Name	Type	Description
dp	DataPoint	DataPoint identifier
id	uint256	The id of the token
handler	address	The handler address NOTE: The handler MUST implement the IFungibleFractionsTransferCallback interface or it will revert when the callback is called

_unregisterSingleIdFungibleFractionTransferCallback

function _unregisterSingleIdFungibleFractionTransferCallback(DataPoint dp, uint256 id, address handler) internal virtual

Function used to unregister a callback for a single id token transfer

Parameters

Name	Type	Description
dp	DataPoint	DataPoint identifier
id	uint256	The id of the token
handler	address	The handler address

_registerAllIdFungibleFractionTransferCallback

function _registerAllIdFungibleFractionTransferCallback(DataPoint dp, address handler) internal virtual

Function used to register a callback for all id token transfers

Parameters

Name	Type	Description
dp	DataPoint	DataPoint identifier
handler	address	The handler address NOTE: The handler MUST implement the IFungibleFractionsTransferCallback interface or it will revert when the callback is called

_unregisterAllIdFungibleFractionTransferCallback

function _unregisterAllIdFungibleFractionTransferCallback(DataPoint dp, address handler) internal virtual

Function used to unregister a callback for all id token transfers

Parameters

Name	Type	Description
dp	DataPoint	DataPoint identifier
handler	address	The handler address
