  - getStream
```
public java.io.InputStream getStream()
```
    Get the input stream being used.
    
    返回:
    
    The current input stream.
  - getEncoding
```
public java.lang.String getEncoding()
```
    Get the encoding being used to convert characters.
    
    指定者:
    
    getEncoding 在类中 Source
    
    返回:
    
    The current encoding.
  - setEncoding
```
public void setEncoding(java.lang.String character_set)
                 throws ParserException
```
    Begins reading from the source with the given character set. If the current encoding is the same as the requested encoding, this method is a no-op. Otherwise any subsequent characters read from this page will have been decoded using the given character set.
    Some magic happens here to obtain this result if characters have already been consumed from this source. Since a Reader cannot be dynamically altered to use a different character set, the underlying stream is reset, a new Source is constructed and a comparison made of the characters read so far with the newly read characters up to the current position. If a difference is encountered, or some other problem occurs, an exception is thrown.
    
    指定者:
    
    setEncoding 在类中 Source
    
    参数:
    
    character_set - The character set to use to convert bytes into characters.
    
    抛出:
    
    ParserException - If a character mismatch occurs between characters already provided and those that would have been returned had the new character set been in effect from the beginning. An exception is also thrown if the underlying stream won't put up with these shenanigans.
  - close
```
public void close()
           throws java.io.IOException
