                                         throws java.io.IOException
        Description copied from class: Message
        Serializes this message to the provided stream. If you just want the raw bytes use bitcoinSerialize().

      • getConnectedOutput

        @Nullable
        public TransactionOutput getConnectedOutput()
        An outpoint is a part of a transaction input that points to the output of another transaction. If we have both sides in memory, and they have been linked together, this returns a pointer to the connected output, or null if there is no such connection.
      • getConnectedPubKeyScript

        public byte[] getConnectedPubKeyScript()
        Returns the pubkey script from the connected output.
        Throws:
        java.lang.NullPointerException - if there is no connected output.
      • getConnectedKey

        @Nullable
        public ECKey getConnectedKey​(KeyBag keyBag)
                              throws ScriptException
        Returns the ECKey identified in the connected output, for either P2PKH, P2WPKH or P2PK scripts. For P2SH scripts you can use getConnectedRedeemData(KeyBag) and then get the key from RedeemData. If the script form cannot be understood, throws ScriptException.
        Returns:
        an ECKey or null if the connected key cannot be found in the wallet.
        Throws:
        ScriptException

        Returns the RedeemData identified in the connected output, for either P2PKH, P2WPKH, P2PK or P2SH scripts. If the script forms cannot be understood, throws ScriptException.
        Returns:
        a RedeemData or null if the connected data cannot be found in the wallet.
