Detailed Description

Represents an NFT state at a particular ledger.

Gets written to nf_tokens table and the like.

The transaction index is only stored because we want to store only the final state of an NFT per ledger. Since we pull this from transactions we keep track of which tx index created this so we can de-duplicate, as it is possible for one ledger to have multiple txs that change the state of the same NFT.

We only set the uri if this is a mint tx, or if we are loading initial state from NFTokenPage objects.

Constructor & Destructor Documentation

NFTsData() [1/4]

NFTsData::NFTsData ( ripple::uint256 const & tokenID, ripple::AccountID const & owner, ripple::Blob const & uri, ripple::TxMeta const & meta )

inline

Construct a new NFTsData object.

Note

This constructor is used when parsing an NFTokenMint tx Unfortunately because of the extreme edge case of being able to re-mint an NFT with the same ID, we must explicitly record a null URI. For this reason, we always write this field as a result of this tx.

Parameters

tokenID	The token ID
owner	The owner
uri	The URI
meta	The transaction metadata

NFTsData() [2/4]

NFTsData::NFTsData ( ripple::uint256 const & tokenID, ripple::AccountID const & owner, ripple::TxMeta const & meta, bool isBurned )

inline

Construct a new NFTsData object.

Note

This constructor is used when parsing an NFTokenBurn or NFTokenAcceptOffer tx

Parameters

tokenID	The token ID
owner	The owner
meta	The transaction metadata
isBurned	Whether the NFT is burned

NFTsData() [3/4]

NFTsData::NFTsData ( ripple::uint256 const & tokenID, std::uint32_t const ledgerSequence, ripple::AccountID const & owner, ripple::Blob const & uri )

inline

Construct a new NFTsData object.

Note

This constructor is used when parsing an NFTokenPage directly from ledger state. Unfortunately because of the extreme edge case of being able to re-mint an NFT with the same ID, we must explicitly record a null URI. For this reason, we always write this field as a result of this tx.

Parameters

tokenID	The token ID
ledgerSequence	The ledger sequence
owner	The owner
uri	The URI

NFTsData() [4/4]

NFTsData::NFTsData ( ripple::uint256 const & tokenID, ripple::TxMeta const & meta, ripple::Blob const & uri )

inline

Construct a new NFTsData object with only the URI changed.

Parameters

tokenID	The token ID
meta	The transaction metadata
uri	The new URI
