    Description copied from interface: MutableObjectIterator
    
    Gets the next element from the collection. The contents of that next element is put into the given reuse object, if the type is mutable.
    
    Specified by:
    
    next in interface MutableObjectIterator<BinaryRowData>
    
    Overrides:
    
    next in class BinaryRowChannelInputViewIterator
    
    Parameters:
    
    reuse - The target object into which to place next element if E is mutable.
    
    Returns:
    
    The filled object or null if the iterator is exhausted.
    
    Throws:
    
    IOException - Thrown, if a problem occurred in the underlying I/O layer or in the serialization / deserialization logic
