Package deltix.qsrv.hf.pub.codec

Class TimeCodec

java.lang.Object

deltix.qsrv.hf.pub.codec.TimeCodec

public class TimeCodec
extends java.lang.Object

Time is binary-encoded in the following ways, depending on scale

Scale	# Bytes	Head Bits	# Bits in Value	Range, Years
s*10-6	7	000	53	569
s*10-3	6	001	45	2225
s	5	010	37	8692
s*10	4	011	29	339
h	3	100	21	477

Method Detail

readTime

public static long readTime(deltix.util.memory.MemoryDataInput in)

readTime

public static void readTime(deltix.util.memory.MemoryDataInput in,
                            deltix.qsrv.hf.pub.TimeStamp time)

readNanoTime

public static long readNanoTime(deltix.util.memory.MemoryDataInput in)

skipTime

public static void skipTime(deltix.util.memory.MemoryDataInput in)

getFieldSize

public static int getFieldSize(long nanoSeconds)

getFieldSize

public static int getFieldSize(long milliseconds,
                               int nanosComponent)

writeNanoTime

public static void writeNanoTime(long nanos,
                                 deltix.util.memory.MemoryDataOutput out)

writeNanoTimeNoScale

public static void writeNanoTimeNoScale(long nanos,
                                        deltix.util.memory.MemoryDataOutput out)

Writes timestamp without value compression. Similar to writeNanoTime(long, deltix.util.memory.MemoryDataOutput) but will always use TIME_SCALE_LONG_NANOS scale so field size is always has MAX_SIZE size.

writeTime

public static void writeTime(deltix.qsrv.hf.pub.InstrumentMessageInfo msg,
                             deltix.util.memory.MemoryDataOutput out)

writeTime

public static void writeTime(long t,
                             deltix.util.memory.MemoryDataOutput out)

Write time in milliseconds

Parameters:

t - milliseconds

out - output
