  - add
```
boolean add(Row row)
     throws AxionException
```
    Ensures that this row collection contains the specified row. Returns true if this row collection changed as a result of the call. (Returns false if this row collection does not permit duplicates and already contains the specified row.)
    
    Parameters:
    
    row - whose presence in this row collection is to be ensured.
    
    Returns:
    
    true if this row collection changed as a result of the call
    
    Throws:
    
    java.lang.UnsupportedOperationException - add is not supported by this row collection.
    
    AxionException
  - clear
```
void clear()
    throws AxionException
```
    Removes all of the rows from this row collection.
    
    Throws:
    
    java.lang.UnsupportedOperationException - if the clear method is not supported by this row collection.
    
    AxionException
  - contains
```
boolean contains(Row row)
          throws AxionException
```
    Returns true if this row collection contains the specified row. More formally, returns true if and only if this row collection contains at least one row e such that (o==null ? e==null : row.equals(e)).
    
    Parameters:
    
    row - whose presence in this row collection is to be tested.
    
    Returns:
    
    true if this row collection contains the specified row
    
    Throws:
    
    AxionException
  - isEmpty
```
boolean isEmpty()
```
    Returns true if this row collection contains no rows.
    
    Returns:
    
    true if this row collection contains no rows
  - rowIterator
```
RowIterator rowIterator()
                 throws AxionException
```
    Returns an iterator over the rows in this row collection. There are no guarantees concerning the order in which the rows are returned (unless this row collection is an instance of some class that provides a guarantee).
    
    Returns:
    
    an Iterator over the rows in this row collection
    
    Throws:
    
    AxionException
  - remove
```
boolean remove(Row row)
        throws AxionException
```
    Removes a single instance of the specified row from this row collection, if it is present.
    
    Parameters:
    
    row - to be removed from this row collection, if present.
    
    Returns:
    
    true if this row collection changed as a result of the call
    
    Throws:
    
    java.lang.UnsupportedOperationException - remove is not supported by this row collection.
    
    AxionException
  - size
```
int size()
```
    Returns the number of rows in this row collection.
