```
public static TStream<java.lang.String> contains(TStream<java.lang.String> stream,
                                                 java.lang.String term)
```
    Create a filtered stream that contains String tuples containing a specific term. An input tuple t is present on the filtered stream if t.contains(term) returns true.
    
    Parameters:
    
    stream - Input stream
    
    term - Term to
    
    Returns:
    
    Filtered stream of tuples that contain term.
  - startsWith
```
public static TStream<java.lang.String> startsWith(TStream<java.lang.String> stream,
                                                   java.lang.String term)
```
    Create a filtered stream that contains String tuples starting with a specific term. An input tuple t is present on the filtered stream if t.startsWith(term) returns true.
    
    Parameters:
    
    stream - Input stream
    
    term - Term to
    
    Returns:
    
    Filtered stream of tuples that contain term.
  - toString
```
public static <T> TStream<java.lang.String> toString(TStream<T> stream)
```
    Create a stream that converts each input tuple to its String representation using toString().
    
    Parameters:
    
    stream - Stream to be converted to String values
    
    Returns:
    
    Stream containing String representations of each tuple on stream.
