Class TeeBCPGInputStream

java.lang.Object

org.pgpainless.decryption_verification.TeeBCPGInputStream

public class TeeBCPGInputStream
extends java.lang.Object

Since we need to update signatures with data from the underlying stream, this class is used to tee out the data. Unfortunately we cannot simply override BCPGInputStream.read() to tee the data out though, since BCPGInputStream.readPacket() inconsistently calls a mix of BCPGInputStream.read() and InputStream.read() of the underlying stream. This would cause the second length byte to get swallowed up. Therefore, this class delegates the teeing to an TeeBCPGInputStream.DelayedTeeInputStream which wraps the underlying stream. Since calling BCPGInputStream.nextPacketTag() reads up to and including the next packets tag, we need to delay teeing out that byte to signature verifiers. Hence, the reading methods of the TeeBCPGInputStream handle pushing this byte to the output stream using TeeBCPGInputStream.DelayedTeeInputStream.squeeze().
