Method Summary

Modifier and Type	Method and Description
int	getActualLength() Actual PDU length (may be less than declared length if fewer bytes are actually available.)
int	getDeclaredLength() PDU length from header
int	getEndIndex() End index within byte buffer of PDU
int	getStartIndex() Start index within byte buffer of PDU This is the start of the payload data that starts after the length and the type, so the PDU actually starts two bytes earlier
byte	getType() PDU type field
static Pdu	parse(byte[] bytes, int startIndex) Parse a PDU from a byte array looking offset by startIndex
