Interface IInvoice

Represents a pre-signed transaction request.
This structure is passed to each configured Signatory and signatory callback method to be given the opportunity to sign the request before submitting it to the netwwork. Typically, the signatory will use its private key to sign the TxBytes serialized representation of the transaciton request.
This is the same series of bytes that are sent to the network along with the signatures collected from the signatories.

Syntax

public interface IInvoice

Properties

Memo

The memo associated with this transaction, for convenience.

Declaration

string Memo { get; }

Property Value

Type	Description
String

TxBytes

The bytes created by serializing the request, including necessary cryptocurrency transfers, into the underlying network's protobuf format. This is the exact sequence of bytes that will be submitted to the network along side the signatures created authorizing the request.

Declaration

ReadOnlyMemory<byte> TxBytes { get; }

Property Value

Type	Description
ReadOnlyMemory<Byte>

TxId

The transaction ID assigned to this request. It, by its nature, contains a timestamp and expiration. Any callback methods must return from signing this transaction with enough time for the transaction to be submitted to the network with sufficient time to process before becomming invalid.

Declaration

TxId TxId { get; }

Property Value

Type	Description
TxId

Methods

AddSignature(KeyType, ReadOnlyMemory<Byte>, ReadOnlyMemory<Byte>)

Adds a signature to the internal list of signatures authorizing this request.

Declaration

void AddSignature(KeyType type, ReadOnlyMemory<byte> publicPrefix, ReadOnlyMemory<byte> signature)

Parameters

Type	Name	Description
KeyType	type	The type of signing key used for this signature.
ReadOnlyMemory<Byte>	publicPrefix	The first few bytes of the public key associated with this signature. This helps the system match signing requrements held internally in the form of public keys with the signatures provided.
ReadOnlyMemory<Byte>	signature	The bytes representing the signature corresponding to the associated private/public key.
