Examples of com.extentech.formats.LEO.BlockByteReader

com.extentech.formats.LEO.BlockByteReader
Provide a translation layer between the block vector and a byte array. A record (Storage, XLSRecord) can retrieve bytes from Scattered blocks transparently. The BlockByteReader Allocates a ByteBuffer containing only byte references contained within Blocs assigned to the implementation class. A Class using this reader will either subclass the reader and manage its blocks, or interact with a shared reader. In the case of a shared reader,

    
    while (child!=null) {
      if (wbh!=null)
      caches.put(Integer.valueOf(child.getName()), child);
      ArrayList<BiffRec> curRecs= new ArrayList();
      BlockByteReader bytes= child.getBlockReader();
      int len= bytes.getLength();
      for (int i = 0; i <= len - 4;) {
        byte[] headerbytes = bytes.getHeaderBytes(i);
        short opcode = ByteTools.readShort(headerbytes[0], headerbytes[1]);
        int reclen = ByteTools.readShort(headerbytes[2], headerbytes[3]);
        BiffRec rec = XLSRecordFactory.getBiffRecord( opcode );
        if (wbh!=null) rec.setDebugLevel(wbh.getDebugLevel()); // KSC: added to propogate debug level
