This extension adds a _afterTokenTransfer hook to all transfer functions, including _mint/Batch and _burn/Batch
This extensions makes use of ERC1155AfterTransfer and allows to track an account holdings, in order to be able to enumerate all tokens of an account
It adds three getters:
function getAccountTokensCount(address account) returns (uint256 count)returns the number of different tokens accountholds
function getAccountTokensByIndex(address account, uint256 index) returns (uint256 tokenId)returns the tokenId at index in the holdings of account
function getAccountTokensPaginated(address account, uint256 cursor, uint256 limit) returns (uint256[] ids, uint256[] balances, uint256 nextCursor)returns a paginated list of ids and balance of tokens held by an account
ids: the list of tokenId held byaccountfor this pagebalances: the balance held for each token inidsnextCursor: the cursor the next page starts at
