Class RandomGroupsHDU

java.lang.Object
  nom.tam.fits.BasicHDU
      nom.tam.fits.RandomGroupsHDU

public class RandomGroupsHDU

extends BasicHDU

Random groups HDUs. Note that the internal storage of random groups is a Object[ngroup][2] array. The first element of each group is the parameter data from that group. The second element is the data. The parameters should be a one dimensional array of the primitive types byte, short, int, long, float or double. The second element is a n-dimensional array of the same type. When analyzing group data structure only the first group is examined, but for a valid FITS file all groups must have the same structure.

isHeader

public static boolean isHeader(Header myHeader)

Is the a random groups header?

Parameters:

myHeader - The header to be tested.

isHeader

public boolean isHeader()

Check that this HDU has a valid header.

Returns:

true if this HDU has a valid header.

manufactureData

public Data manufactureData()

Create a FITS Data object corresponding to this HDU header.

Specified by:

manufactureData in class BasicHDU

Returns:

An unfilled Data object which can be used to read in the data for this HDU.
