Detailed Description

read FORTRAN binary data ,

This class reads FORTRAN binary data. FORTRAN binary data is always written in chunks of several bytes, where each chunk is preceded and followed by a 4-byte integer byte-count. This class takes care of this structure of byte-counts an returns only the real data (omitting the counts).

No buffering is done, because we rely on stream-buffering.

By creating the object the reading process is initialized. For convenient access I/O operators are provided.

No checking for block alignment is performed. This means, the class does not complain in case the first three bytes of a double are at the end of one block and the next five bytes are at the beginning of the next block. The class just ensures that block byte-counts are skipped.
