# CharsetEncoder Class Reference

Inherits ObjectImpl.

List of all members.

## Detailed Description

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

## Public Member Functions

virtual | ~CharsetEncoder ()
| Destructor.
virtual log4cxx_status_t | encode (const LogString &in, LogString::const_iterator &iter, ByteBuffer &out)=0
| Encodes as many characters from the input string as possible to the output buffer.
virtual void | reset ()
| Resets any internal state.
virtual void | flush (ByteBuffer &out)
| Flushes the encoder.

## Static Public Member Functions

static CharsetEncoderPtr | getDefaultEncoder ()
| Get encoder for default charset.
static CharsetEncoderPtr | getEncoder (const LogString &charset)
| Get encoder for specified character set.
static CharsetEncoderPtr | getUTF8Encoder ()
| Get encoder for UTF-8.
static void | encode (CharsetEncoderPtr &enc, const LogString &src, LogString::const_iterator &iter, ByteBuffer &dst)
| Encodes a string replacing unmappable characters with escape sequences.
static bool | isError (log4cxx_status_t stat)
| Determines if the return value from encode indicates an unconvertable character.

## Protected Member Functions

| CharsetEncoder ()
| Protected constructor.

## Constructor & Destructor Documentation

CharsetEncoder | ( |  | ) | `[protected]`

| Protected constructor.

virtual ~CharsetEncoder | ( |  | ) | `[virtual]`

| Destructor.

## Member Function Documentation

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.

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 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.
