Class Issue

Represents an Issue (currency + optional issuer, or MPT issuance ID). Supports XRP, IOU (currency+issuer), and MPT (mpt_issuance_id) formats. Binary format: XRP: 20 bytes (currency, all zeros) IOU: 40 bytes (20 currency + 20 issuer) MPT: 44 bytes (20 account + 20 noAccount marker + 4 sequence) MPT binary layout matches rippled's STIssue serialization:

  • 20 bytes: AccountID extracted from MPTokenIssuanceID
  • 20 bytes: noAccount() = uint160{1} (19 zeros + 0x01)
  • 4 bytes: token sequence (raw bytes from MPTID, effectively little-endian due to rippled's memcpy+add32 pattern on LE platforms)

FromParser(BinaryParser, int?)

Read from binary parser: supports XRP (20 bytes), IOU (40 bytes), and MPT (44 bytes). Reads 20 bytes as "currency" (or account for MPT), then 20 bytes as "issuer". If issuer == noAccount (uint160{1}), it's MPT: reads 4 more bytes as sequence.

Declaration
public static Issue FromParser(BinaryParser parser, int? hint = null)
Parameters
Type Name Description
BinaryParser parser
int? hint
Returns
