readEntireMessage

public ucar.ma2.ArrayStructure readEntireMessage(ucar.nc2.Structure s,
                                                 Message proto,
                                                 Message m,
                                                 ucar.unidata.io.RandomAccessFile raf,
                                                 Formatter f)
                                          throws IOException

Read all datasets from a single message

Parameters:

s - outer variables

proto - prototype message, has been processed

m - read this message

raf - from this file

f - output bit count debugging info (may be null)

Returns:

ArrayStructure with all the data from the message in it.

Throws:

IOException - on read error

readData

public void readData(ucar.ma2.ArrayStructureMA ama,
                     Message m,
                     ucar.unidata.io.RandomAccessFile raf,
                     ucar.ma2.Range r,
                     Formatter f)
              throws IOException

Read some or all datasets from a single message

Parameters:

ama - place data into here in order (may be null). iterators must be already set.

m - read this message

raf - from this file

r - which datasets, relative to this message. null == all.

f - output bit count debugging info (may be null)

Throws:

IOException - on read error

setIterators

public static void setIterators(ucar.ma2.ArrayStructureMA ama)
