    Returns:
    
    parsed criterion.
  - convertToMap
```
public abstract java.util.Map convertToMap(Criterion criterion)
```
    Convert criterion to map representation.
    
    Parameters:
    
    criterion - - criterion to convert.
    
    Returns:
    
    map representation of criterion.
