Transaction.calculateSignature介绍

[英]Calculates a signature that is valid for being inserted into the input at the given position. This is simply a wrapper around calling Transaction#hashForSignature(int,byte[],org.bitcoinj.core.Transaction.SigHash,boolean)followed by ECKey#sign(Sha256Hash) and then returning a new TransactionSignature.
[中]计算可在给定位置插入到输入中的有效签名。这是一个简单的包装器，用于调用Transaction#hashForSignature（int，byte[]，org.bitconj.core.Transaction.sigash，boolean），然后调用ECKey#sign（Sha256Hash），然后返回一个新的TransactionSignature。
