isApprovedForAll

function isApprovedForAll(address account, address operator) public view returns (bool operators_)

safeTransferFrom

function safeTransferFrom(address _from, address _to, uint256 _id, uint256 _value, bytes _data) external

Transfers _value amount of an _id from the _from address to the _to address specified (with safety call). @dev Caller must be approved to manage the tokens being transferred out of the _from account (see "Approval" section of the standard). MUST revert if _to is the zero address. MUST revert if balance of holder for token _id is lower than the _value sent. MUST revert on any other error. MUST emit the TransferSingle event to reflect the balance change (see "Safe Transfer Rules" section of the standard). After the above conditions are met, this function MUST check if _to is a smart contract (e.g. code size > 0). If so, it MUST call onERC1155Received on _to and act appropriately (see "Safe Transfer Rules" section of the standard). @param _from Source address @param _to Target address @param _id ID of the token type @param _value Transfer amount @param _data Additional data with no specified format, MUST be sent unaltered in call to onERC1155Received on _to

safeBatchTransferFrom

function safeBatchTransferFrom(address _from, address _to, uint256[] _ids, uint256[] _values, bytes _data) external

Transfers _values amount(s) of _ids from the _from address to the _to address specified (with safety call). @dev Caller must be approved to manage the tokens being transferred out of the _from account (see "Approval" section of the standard). MUST revert if _to is the zero address. MUST revert if length of _ids is not the same as length of _values. MUST revert if any of the balance(s) of the holder(s) for token(s) in _ids is lower than the respective amount(s) in _values sent to the recipient. MUST revert on any other error. MUST emit TransferSingle or TransferBatch event(s) such that all the balance changes are reflected (see "Safe Transfer Rules" section of the standard). Balance changes and events MUST follow the ordering of the arrays (_ids[0]/_values[0] before _ids[1]/_values[1], etc). After the above conditions for the transfer(s) in the batch are met, this function MUST check if _to is a smart contract (e.g. code size > 0). If so, it MUST call the relevant ERC1155TokenReceiver hook(s) on _to and act appropriately (see "Safe Transfer Rules" section of the standard). @param _from Source address @param _to Target address @param _ids IDs of each token type (order and length must match _values array) @param _values Transfer amounts per token type (order and length must match _ids array) @param _data Additional data with no specified format, MUST be sent unaltered in call to the ERC1155TokenReceiver hook(s) on _to
