      • skipBytes

        public void skipBytes​(long count)
        Description copied from class: DataInput
        Skip over numBytes bytes. This method may skip bytes in whatever way is most optimal, and may not have the same behavior as reading the skipped bytes. In general, negative numBytes are not supported.
        Specified by:
        skipBytes in class DataInput
      • readVInt

        public int readVInt()
        Description copied from class: DataInput
        Reads an int stored in variable-length format. Reads between one and five bytes. Smaller values take fewer bytes. Negative numbers are supported, but should be avoided.

        The format is described further in DataOutput.writeVInt(int).

                              int len)
        Description copied from class: DataInput
        Reads a specified number of bytes into an array at the specified offset.
        Specified by:
        readBytes in class DataInput
        b - the array to read bytes into
        offset - the offset in the array to start storing bytes
        len - the number of bytes to read
