Method Detail

getData

public final float[] getData()

Grib2 data unpacked as floats.

Returns:

data

isStaticMissingValueInUse

public static boolean isStaticMissingValueInUse()

flag to signifly if a static Missing Value is used. Since it's possible to have different missing values in a Grib file, the first record's missing value might not be the correct missing value for the current record. If a static missing value is used (float.NaN) then there will be no conflict of missing value processing.

Returns:

staticMissingValueInUse boolean

setStaticMissingValueInUse

public static void setStaticMissingValueInUse(boolean staticMissingValueInUse)

flag to signifly if a static Missing Value is used. Since it's possible to have different missing values in a Grib file, the first record's missing value might not be the correct missing value for the current record. If a static missing value is used (float.NaN) then there will be no conflict of missing value processing.

Parameters:

staticMissingValueInUse - boolean
