- Field Detail
  - public final boolean ansiSupported
    
    Whether ansi support is available
  - public final PrintWriter err
    
    Preferred error output writer.
  - public final OutputStream errorStream
    
    Raw error output stream.
  - public final Reader in
    
    Preferred input reader.
  - public final InputStream inputStream
    
    Raw input stream.
  - public final PrintWriter out
    
    Preferred output writer.
  - public final OutputStream outputStream
    
    Raw output stream.
- Constructor Detail
  - public IO(InputStream inputStream, OutputStream outputStream, OutputStream errorStream)
    
    Construct a new IO container.
  - public IO()
    
    Construct a new IO container using system streams.
- Method Detail
  - public void close()
    
    Close all streams.
  - public void flush()
    
    Flush both output streams.
  - public IO.Verbosity getVerbosity()
    
    Returns the verbosity level.
  - public boolean isDebug()
    
    Check if the verbosity level is set to Verbosity.DEBUG.
    For general usage, when debug output is required, it is better to use the logging facility instead.
  - public boolean isInfo()
    
    Check if the verbosity level is set to Verbosity.INFO.
  - public boolean isQuiet()
    
    Check if the verbosity level is set to Verbosity.QUIET.
  - public boolean isVerbose()
    
    Check if the verbosity level is set to Verbosity.VERBOSE.
  - public void setVerbosity(IO.Verbosity verbosity)
    
    Set the verbosity level.
  - protected PrintWriter tryConstructRenderWriter(OutputStream stream)
    
    Attempts to create an ANSI-aware writer for the supplied stream.
    Parameters:
    stream - the output stream to wrap
    Returns:
    an ANSI render writer, or null if ANSI support is unavailable
