Row (LearnLib 0.17.0 API)

Type Parameters:

I - input symbol type
```
public interface Row<I>
```
A row in an observation table. Minimally, a row consists of a prefix (the row label) and a unique identifier in its observation table which remains constant throughout the whole process.
Apart from that, a row is also associated with contents (via an integer id). The prefix of a row may be either a short or long prefix. In the former case, the row will also have successor rows (one-step futures) associated with it.

  - getRowContentId
```
int getRowContentId()
```

  - getLabel
```
Word<I> getLabel()
```

    Returns:
    
    the label of this row
  - isShortPrefixRow
```
boolean isShortPrefixRow()
```
    Retrieves whether this row is a short or a long prefix row.
    
    Returns:
    
    true if this row is a short prefix row, false otherwise.
  - getSuccessor
```
Row<I> getSuccessor(int pos)
```
    Retrieves the successor row for this short label row and the given alphabet symbol (by index). If this is no short label row, an exception might occur.
    
    Parameters:
    
    pos - the index of the alphabet symbol.
