Constructor Detail

Grib1Record

public Grib1Record(byte[] header,
           Grib1SectionIndicator is,
           Grib1SectionGridDefinition gdss,
           Grib1SectionProductDefinition pdss,
           Grib1SectionBitMap bitmap,
           Grib1SectionBinaryData dataSection)

Construction for Grib1Record.

Parameters:

header - Grib header

is - Grib1IndicatorSection

gdss - Grib1GridDefinitionSection

pdss - Grib1ProductDefinitionSection

bitmap - Grib1SectionBitMap

dataSection - Grib1SectionData

Grib1Record

public Grib1Record(RandomAccessFile raf)
            throws IOException

Construct record by reading raf, no checking

Parameters:

raf - positioned at start of message: the 'G' in "GRIB"

Throws:

IOException - on read error

Method Detail

getHeader

getDataSection

public Grib1SectionBinaryData getDataSection()

getReferenceDate

public CalendarDate getReferenceDate()

getFile

public int getFile()

setFile

public void setFile(int file)

readData

public float[] readData(RandomAccessFile raf)
                 throws IOException

Throws:

IOException

readDataRaw

public float[] readDataRaw(RandomAccessFile raf,
                  GribData.InterpolationMethod method)
                    throws IOException

showDataInfo

public void showDataInfo(RandomAccessFile raf,
                Formatter f)
                  throws IOException

Throws:

IOException

readData

public static float[] readData(RandomAccessFile raf,
               long startPos)
                        throws IOException

Read data array by first reading in GribRecord. All sections are read in, so scanMode is from the datafile, not the index.

Parameters:

raf - from this RandomAccessFile

startPos - message starts here

Returns:

data as float[] array

Throws:

IOException - on read error

Throws:

IOException

readRawData

public int[] readRawData(RandomAccessFile raf)
                  throws IOException

Throws:

IOException
