Method Detail

readEntireMessage

public ArrayStructure readEntireMessage(Structure s,
                                        Message proto,
                                        Message m,
                                        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(ArrayStructureMA ama,
                     Message m,
                     RandomAccessFile raf,
                     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(ArrayStructureMA ama)
