Interface for binary input stream classes.
virtual sal_Int32 readData(StreamDataSequence &orData, sal_Int32 nBytes, size_t nAtomSize=1)=0
Derived classes implement reading nBytes bytes to the passed sequence.
bool isEof() const
Returns true, if the stream position is invalid (EOF).

bool readDirRecord(sal_uInt16 &rnRecId, StreamDataSequence &rRecData, BinaryInputStream &rInStrm)
Reads the next record from the VBA directory stream 'dir'.
