net.corda.core.crypto.SignatureMetadata

public class SignatureMetadata

SignatureMeta is required to add extra meta-data to a transaction's signature. It currently supports platformVersion only, but it can be extended to support a universal digital signature model enabling partial signatures and attaching extra information, such as a user's timestamp or other application-specific fields.

Constructor Detail

SignatureMetadata

public SignatureMetadata(int platformVersion,
                         int schemeNumberID)

SignatureMeta is required to add extra meta-data to a transaction's signature.
