IsSpecialVariantChar(TUint, TUint &, TUint &, TUint &)

IMPORT_C TBool	IsSpecialVariantChar	(	TUint	aCode,
			TUint &	aRangeStart,
			TUint &	aRangeEnd,
			TUint &	aClass
		)	[static]

Converts Unicode character into line breaking class for special variant.

Parameters

TUint aCode	Input Unicode value.
TUint & aRangeStart	Returns the start of the contiguous range of characters including aCode that have the returned line breaking class.
TUint & aRangeEnd	Returns the end of the contiguous range of characters including aCode that have the returned line breaking class.
TUint & aClass	The line breaking class for aCode.

LineBreakClass(TUint, TUint &, TUint &)

TUint	LineBreakClass	(	TUint	aCode,
			TUint &	aRangeStart,
			TUint &	aRangeEnd
		)	const [virtual]

Converts Unicode character into line breaking class.

Parameters

TUint aCode	Input Unicode value.
TUint & aRangeStart	Returns the start of the contiguous range of characters including aCode that have the returned line breaking class.
TUint & aRangeEnd	Returns the end of the contiguous range of characters including aCode that have the returned line breaking class.

LineBreakPossible(TUint, TUint, TBool)

TBool	LineBreakPossible	(	TUint	aPrevClass,
			TUint	aNextClass,
			TBool	aHaveSpaces
		)	const [virtual]

Returns whether line breaks are legal between a character of line breaking class aPrevClass and aNextClass, with intervening spaces or not as determined by aHaveSpaces.

Parameters

TUint aPrevClass	The class before the potential line break.
TUint aNextClass	The class after the potential line break.
TBool aHaveSpaces	Whether spaces separate the characters.
