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 )

inlinestatic

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

virtual void reset ( )

virtual

Resets any internal state.
