## Detailed Description

An engine to transform LogStrings into bytes for the specific character set.

## Constructor & Destructor Documentation

CharsetEncoder | ( |  | ) |
| protected

Protected constructor.

virtual ~CharsetEncoder | ( |  | ) |
| virtual

Destructor.

## Member Function Documentation

static void encode | ( | CharsetEncoderPtr & | enc,
|  | const LogString & | src,
|  | LogString::const_iterator & | iter,
|  | ByteBuffer & | dst
| ) |  |
| static

Encodes a string replacing unmappable characters with escape sequences.

virtual log4cxx_status_t encode | ( | const LogString & | in,
|  | LogString::const_iterator & | iter,
|  | ByteBuffer & | out
| ) |  |
| pure virtual

Encodes as many characters from the input string as possible to the output buffer.

Parameters

  in | input string
  iter | position in string to start.
  out | output buffer.

Returns
  APR_SUCCESS unless a character can not be represented in the encoding.

virtual void flush | ( | ByteBuffer & | out | ) |
| virtual

Flushes the encoder.

static CharsetEncoderPtr getDefaultEncoder | ( |  | ) |
| static

Get encoder for default charset.

static CharsetEncoderPtr getEncoder | ( | const LogString & | charset | ) |
| static

Get encoder for specified character set.

Parameters

  charset | the following values should be recognized: "US-ASCII", "ISO-8859-1", "UTF-8", "UTF-16BE", "UTF-16LE".

Returns
  encoder.

Exceptions

  IllegalArgumentException | if encoding is not recognized.

static CharsetEncoderPtr getUTF8Encoder | ( |  | ) |
| static

Get encoder for UTF-8.

static bool isError | ( | log4cxx_status_t | stat | ) |
| inline static

Determines if the return value from encode indicates an unconvertable character.

virtual void reset | ( |  | ) |
| virtual

Resets any internal state.
