  - writeTo
```
public static final void writeTo(java.io.InputStream in,
           java.io.OutputStream out)
                          throws java.io.IOException
```
    Read bytes from an input stream and write them to an output stream.
    
    Parameters:
    in - the input stream to read from.
    out - the output stream to write to.
    
    Throws:
    
    java.io.IOException - if there is an error reading or writing bytes.
  - writeTo
```
public static final void writeTo(java.io.Reader in,
           java.io.Writer out)
                          throws java.io.IOException
```
    Read characters from an input stream and write them to an output stream.
    
    Parameters:
    in - the reader to read from.
    out - the writer to write to.
    
    Throws:
    
    java.io.IOException - if there is an error reading or writing characters.
  - getCharset
```
public static final java.nio.charset.Charset getCharset(MediaType m)
```
    Get the character set from a media type.
    The character set is obtained from the media type parameter "charset". If the parameter is not present the UTF8 charset is utilized.
    
    Parameters:
    m - the media type.
    
    Returns:
    the character set.
  - readFromAsString
```
public static final java.lang.String readFromAsString(java.io.InputStream in,
                                MediaType type)
                                               throws java.io.IOException
```
    Read the bytes of an input stream and convert to a string.
    
    Parameters:
    in - the input stream to read from.
    type - the media type that determines the character set defining how to decode bytes to charaters.
    
    Returns:
    the string.
    
    Throws:
    
    java.io.IOException - if there is an error reading from the input stream.
  - readFromAsString
```
public static final java.lang.String readFromAsString(java.io.Reader reader)
                                               throws java.io.IOException
```
    Read the characters of a reader and convert to a string.
    
    Parameters:
    reader - the reader
    
    Returns:
    the string
    
    Throws:
    
    java.io.IOException - if there is an error reading from the reader.
  - writeToAsString
```
public static final void writeToAsString(java.lang.String s,
                   java.io.OutputStream out,
                   MediaType type)
                                  throws java.io.IOException
```
    Convert a string to bytes and write those bytes to an output stream.
    
    Parameters:
    s - the string to convert to bytes.
    out - the output stream to write to.
    type - the media type that determines the character set defining how to decode bytes to characters.
    
    Throws:
    
    java.io.IOException
