-/**
- * InputStream for handshake data, used internally only. Contains the
- * handshake message buffer and methods to parse them.
- *
- * Once a new handshake record arrives, it is buffered in this class until
- * processed by the Handshaker. The buffer may also contain incomplete
- * handshake messages in case the message is split across multiple records.
- * Handshaker.processRecord deals with all that. It may also contain
- * handshake messages larger than the default buffer size (e.g. large
- * certificate messages). The buffer is grown dynamically to handle that.
- *
- * Note that this class only handles Handshake messages in TLS format.
- * DTLS Handshake messages should be converted into TLS format before
- * calling into this method.
