  `IOException` - if an I/O error occurs

#### Row

    public Row()

The default constructor for the Row object.

#### Row

    public Row(Row old)

Construct a Row using the cells of the given Row.

Parameters:
  `old` - the Row to copy

### Method Detail

#### setCmd

    public void setCmd(Character way,
                       int cmd)

Set the command in the Cell of the given Character to the given integer.

Parameters:
  `way` - the Character defining the Cell
  `cmd` - the new command

#### setRef

    public void setRef(Character way,
                       int ref)

Set the reference to the next row in the Cell of the given Character to the given integer.

Parameters:
  `way` - the Character defining the Cell
  `ref` - The new ref value

#### getCells

    public int getCells()

Return the number of cells in use.

Returns:
  the number of cells in use

#### getCellsPnt

    public int getCellsPnt()

Return the number of references (how many transitions) to other rows.

Returns:
  the number of references

#### getCellsVal

    public int getCellsVal()

Return the number of patch commands saved in this Row.

Returns:
  the number of patch commands

#### getCmd

    public int getCmd(Character way)

Return the command in the Cell associated with the given Character.

Parameters:
  `way` - the Character associated with the Cell holding the desired command
Returns:
  the command

#### getCnt

    public int getCnt(Character way)

Return the number of patch commands were in the Cell associated with the given Character before the Trie containing this Row was reduced.

Parameters:
  `way` - the Character associated with the desired Cell
Returns:
  the number of patch commands before reduction

#### getRef

    public int getRef(Character way)

Return the reference to the next Row in the Cell associated with the given Character.

Parameters:
  `way` - the Character associated with the desired Cell
Returns:
  the reference, or -1 if the Cell is `null`

#### store
