checkInvariant close compressedVectorNode dump isOpen read read seek

void seek ( int64_t  recordNumber ) Set record number of CompressedVectorNode where next read will start. Parameters: [in] recordNumber The index of record in ComressedVectorNode where next read using this CompressedVectorReader will start. This function may be called at any time (as long as ImageFile and CompressedVectorReader are open). The next read will start at the given recordNumber. It is not an error to seek to recordNumber = childCount() (i.e. to one record past end of CompressedVectorNode). Precondition: recordNumber <= childCount() of CompressedVectorNode. The associated ImageFile must be open. This CompressedVectorReader must be open (i.e isOpen()) Exceptions: E57_ERROR_BAD_API_ARGUMENT E57_ERROR_IMAGEFILE_NOT_OPEN E57_ERROR_READER_NOT_OPEN E57_ERROR_BAD_CV_PACKET E57_ERROR_LSEEK_FAILED E57_ERROR_READ_FAILED E57_ERROR_BAD_CHECKSUM E57_ERROR_INTERNAL All objects in undocumented state See also: SourceDestBufferNumericCreate.cpp example, CompressedVectorNode::reader
