Functions

◆ aliases()

QList< QByteArray > QUtf32Codec::aliases ( ) const

virtual

Subclasses can return a number of aliases for the codec in question.

Standard aliases for codecs can be found in the IANA character-sets encoding file.

Reimplemented from QTextCodec.

Reimplemented in QUtf32LECodec, and QUtf32BECodec.

Definition at line 630 of file qutfcodec.cpp.

 {
     QList<QByteArray> list;
     return list;
 }

◆ convertFromUnicode()

QByteArray QUtf32Codec::convertFromUnicode	(	const QChar *	input,
		int	number,
		ConverterState *	state
	)		const

virtual

QTextCodec subclasses must reimplement this function.

Converts the first number of characters from the input array from Unicode to the encoding of the subclass, and returns the result in a QByteArray.

state can be 0 in which case the conversion is stateless and default conversion rules should be used. If state is not 0, the codec should save the state after the conversion in state, and adjust the remainingChars and invalidChars members of the struct.

Implements QTextCodec.

Definition at line 610 of file qutfcodec.cpp.

 {
     return QUtf32::convertFromUnicode(uc, len, state, e);
 }

◆ convertToUnicode()

QString QUtf32Codec::convertToUnicode	(	const char *	chars,
		int	len,
		ConverterState *	state
	)		const

virtual

QTextCodec subclasses must reimplement this function.

Converts the first len characters of chars from the encoding of the subclass to Unicode, and returns the result in a QString.

state can be 0, in which case the conversion is stateless and default conversion rules should be used. If state is not 0, the codec should save the state after the conversion in state, and adjust the remainingChars and invalidChars members of the struct.

Implements QTextCodec.

Definition at line 615 of file qutfcodec.cpp.

 {
     return QUtf32::convertToUnicode(chars, len, state, e);
 }

◆ mibEnum()

int QUtf32Codec::mibEnum ( ) const

virtual

Subclasses of QTextCodec must reimplement this function.

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

Implements QTextCodec.

Reimplemented in QUtf32LECodec, and QUtf32BECodec.

Definition at line 620 of file qutfcodec.cpp.

 {
     return 1017;
 }

◆ name()

QByteArray QUtf32Codec::name ( ) const

virtual

QTextCodec subclasses must reimplement this function.

It returns the name of the encoding supported by the subclass.

If the codec is registered as a character set in the IANA character-sets encoding file this method should return the preferred mime name for the codec if defined, otherwise its name.

Implements QTextCodec.

Reimplemented in QUtf32LECodec, and QUtf32BECodec.

Definition at line 625 of file qutfcodec.cpp.

 {
     return "UTF-32";
 }
