public DataRecord(DataRecord record)

Method Detail

addBlockette

public void addBlockette(Blockette b)
                  throws SeedFormatException

Adds a blockette to the record. The number of blockettes in the header is incremented automatically.

Overrides:

addBlockette in class SeedRecord

Throws:

SeedFormatException

recheckDataOffset

protected void recheckDataOffset()
                          throws SeedFormatException

Throws:

SeedFormatException

getData

public byte[] getData()

returns the data from this data header unparsed, as a byte array in the format from blockette 1000. The return type is byte[], so the caller must decode the data based on its format.

decompress

public edu.iris.dmc.seedcodec.DecompressedData decompress()
                                                   throws SeedFormatException,
                                                          edu.iris.dmc.seedcodec.UnsupportedCompressionType,
                                                          edu.iris.dmc.seedcodec.CodecException

Decompress the data in this record according to the compression type in the header.

Returns:

Throws:

SeedFormatException - if no blockette 1000 present

edu.iris.dmc.seedcodec.UnsupportedCompressionType

edu.iris.dmc.seedcodec.CodecException

setData

public void setData(byte[] data)
             throws SeedFormatException

Throws:

SeedFormatException

getDataSize

public int getDataSize()

getSampleRate

public float getSampleRate()

getPredictedNextStartBtime

public Btime getPredictedNextStartBtime()

returns the predicted start time of the next record, ie begin + numSample*period Note that this will use the more accurate sample rate in a blockette100 if it exists.

getBtimeRange

public BtimeRange getBtimeRange()

getLastSampleBtime

public Btime getLastSampleBtime()

return a Btime structure containing the derived last sample time for this record. Note that this will use the more accurate sample rate in a blockette100 if it exists.

getStartBtime

public Btime getStartBtime()

Gets start Btime from header, convenience method.

getStartTime

public java.lang.String getStartTime()

Gets start time from header, convenience method.

getEndTime

public java.lang.String getEndTime()

get the value of end time. derived from Start time, sample rate, and number of samples. Note this is not the time of the last sample, but rather the predicted begin time of the next record. Note that this will use the more accurate sample rate in a blockette100 if it exists.

Returns:

the value of end time

getLastSampleTime

public java.lang.String getLastSampleTime()

get the value of end time. derived from Start time, sample rate, and number of samples. Note that this will use the more accurate sample rate in a blockette100 if it exists.

Returns:

the value of end time

getHeader

public DataHeader getHeader()

toByteArray

public byte[] toByteArray()

write

public void write(java.io.DataOutputStream dos)
           throws java.io.IOException

Throws:

java.io.IOException

printData

public void printData(java.io.PrintWriter out)

readDataRecord

public static SeedRecord readDataRecord(java.io.DataInput inStream,
                                        DataHeader header,
                                        int defaultRecordSize)
                                 throws java.io.IOException,
                                        SeedFormatException

Throws:

java.io.IOException

SeedFormatException

setRecordSize

public void setRecordSize(int recordSize)
                   throws SeedFormatException

Throws:

SeedFormatException

public static java.lang.String oneLineSummaryKey()

oneLineSummary

public java.lang.String oneLineSummary()

toString

public java.lang.String toString()

Overrides:

toString in class SeedRecord
