public final class HourMinute extends AbstractLazyEncodedByteArray implements FastSerializable
Class HourMinute represents a time HH:MM in two octets, BCD encoded.The API offered by this class is as if the type were specified in ASN.1 as follows.
HourMinute ::= SEQUENCE { hour INTEGER, minute INTEGER, }
The class takes care of encoding the field values into a byte-array and decoding field values from a byte-array, the encoded representation being as tabulated below. The digits are encoded separately in BCD.Data Encoding - based on comment in ASN.1 module Core-INAP-CS1-DataTypes 8 7 6 5 4 3 2 1 Octet 0 Hours units Hours tens Octet 1 Minutes units Minutes tens
For example, 12:15 is encoded as 2151 (assuming the high nibble is written before the low nibble).- See Also:
