Class SignableData

net.corda.core.crypto.SignableData

public class SignableData

A class SignableData object is the packet actually signed. It works as a wrapper over transaction id and signature metadata. Note that when multi-transaction signing (signing a block of transactions) is used, the root of the Merkle tree (having transaction IDs as leaves) is actually signed and thus txId refers to this root and not a specific transaction.
