Descripción detallada

The QEucKrCodec class provides conversion to and from EUC-KR character sets.

The QEucKrCodec class subclasses QTextCodec to provide support for EUC-KR, the main legacy encoding for UNIX machines in Korea.

It was largely written by Mizi Research Inc. Here is the copyright statement for the code as it was at the point of contribution. Trolltech's subsequent modifications are covered by the usual copyright for Qt.

QCString QEucKrCodec::fromUnicode	(	const QString &	uc,
		int &	lenInOut
	)		const [virtual]

Reimplementado de QTextCodec.

QCString QEucKrCodec::fromUnicode	(	const QString &	uc,
		int &	lenInOut
	)		const [virtual]

QTextCodec subclasses must reimplement either this function or makeEncoder(). It converts the first lenInOut characters of uc from Unicode to the encoding of the subclass. If lenInOut is negative or too large, the length of uc is used instead.

Converts lenInOut characters (not bytes) from uc, producing a QCString. lenInOut will be set to the length of the result (in bytes).

The default implementation makes an encoder with makeEncoder() and converts the input with that. Note that the default makeEncoder() implementation makes an encoder that simply calls this function, hence subclasses must reimplement one function or the other to avoid infinite recursion.

Implementa QTextCodec.

int QEucKrCodec::heuristicContentMatch	(	const char *	chars,
		int	len
	)		const [virtual]

QTextCodec subclasses must reimplement this function. It examines the first len bytes of chars and returns a value indicating how likely it is that the string is a prefix of text encoded in the encoding of the subclass. A negative return value indicates that the text is detectably not in the encoding (e.g. it contains characters undefined in the encoding). A return value of 0 indicates that the text should be decoded with this codec rather than as ASCII, but there is no particular evidence. The value should range up to len. Thus, most decoders will return -1, 0, or -len.

The characters are not null terminated.

int QEucKrCodec::heuristicNameMatch

)

const [virtual]

Returns a value indicating how likely it is that this decoder is appropriate for decoding some format that has the given name. The name is compared with the hint.

A good match returns a positive number around the length of the string. A bad match is negative.

The default implementation calls simpleHeuristicNameMatch() with the name of the codec.

QTextDecoder* QEucKrCodec::makeDecoder

(

)

const [virtual]

Creates a QTextDecoder which stores enough state to decode chunks of char* data to create chunks of Unicode data. The default implementation creates a stateless decoder, which is only sufficient for the simplest encodings where each byte corresponds to exactly one Unicode character.

The caller is responsible for deleting the returned object.

virtual int QEucKrCodec::mibEnum

const [virtual]

Subclasses of QTextCodec must reimplement this function. It returns the MIBenum (see the IANA character-sets encoding file for more information). It is important that each QTextCodec subclass returns the correct unique value for this function.

const char* QEucKrCodec::name

(

)

const [virtual]

QTextCodec subclasses must reimplement this function. It returns the name of the encoding supported by the subclass. When choosing a name for an encoding, consider these points: On X11, heuristicNameMatch( const char * hint ) is used to test if a the QTextCodec can convert between Unicode and the encoding of a font with encoding hint, such as "iso8859-1" for Latin-1 fonts, "koi8-r" for Russian KOI8 fonts. The default algorithm of heuristicNameMatch() uses name(). Some applications may use this function to present encodings to the end user.

QString QEucKrCodec::toUnicode	(	const char *	chars,
		int	len
	)		const [virtual]

QTextCodec subclasses must reimplement this function or makeDecoder(). It converts the first len characters of chars to Unicode.

The default implementation makes a decoder with makeDecoder() and converts the input with that. Note that the default makeDecoder() implementation makes a decoder that simply calls this function, hence subclasses must reimplement one function or the other to avoid infinite recursion.
