  - openStream
```
java.io.PrintStream openStream(java.lang.String label)
                        throws java.io.IOException
```
    Retrieve a print stream for output using the given label. Note that multiple labels MAY result in the same PrintStream, so you should be printing to only one stream at a time to avoid mixing outputs.
    
    Parameters:
    
    label - Output label.
    
    Returns:
    
    stream object for the given label
    
    Throws:
    
    java.io.IOException - on IO error
  - closeStream
```
void closeStream(java.io.PrintStream stream)
```
    Close the given output stream (Note: when writing to a single stream output, it will actually not be closed!)
    
    Parameters:
    
    stream - Stream to close
  - close
```
void close()
    throws java.io.IOException
```
    Close stream factory.
