virtual void IAttributeStrand::CharRootStyleDiffs_ApplyAtPaste	(	TextIndex	start,
		int32	length,
		const UID &	charRootStyle,
		const UID &	paraRootStyle,
		const AttributeBossList *	diffAttrs,
		const AttributeBossList *	charDest_SrcRootStyleDiffs,
		const ITextModel *	model
	)

pure virtual

For internal use only.

virtual void IAttributeStrand::DoApplyOverrides	(	const ITextModel *	model,
		ClassID	whichStrand,
		TextIndex *	startpos,
		int32 *	numchars,
		const AttributeBossList *	over
	)

pure virtual

Applies text attributes to a range.

Parameters

model	IN text model.
whichStrand	IN whether these are character or a paragraph attributes.
startpos	IN start of apply range.
numchars	IN apply range length.
over	IN attributes to apply. Adjusts startpos & numchars to encompass EXACTLY ALL the characters within the intersecting paragraphs.

virtual void IAttributeStrand::DoApplyTextStyle	(	const ITextModel *	model,
		ClassID	which,
		TextIndex *	pstartpos,
		int32 *	pnumchars,
		UID	styleref,
		bool16	removeAll,
		bool16	keepOldStyleAsOverrides = `kTrue`
	)

pure virtual

Applies a text style to a range.

Parameters

model	IN text model.
which	IN whether this is a character or a paragraph style.
pstartpos	IN start of apply range.
pnumchars	IN length of apply range.
styleref	IN applied style uid
removeall	IN whether to remove all overrides.
keepOldStyleAsOverrides	IN whether to apply current style as overrides before setting new style. Adjusts pstartpos & pnumchars to encompass EXACTLY ALL the characters within the intersecting paragraphs.

virtual void IAttributeStrand::DoClearOverrides	(	const ITextModel *	model,
		ClassID	whichStrand,
		TextIndex *	startpos,
		int32 *	numchars,
		const AttributeBossList *	over
	)

pure virtual

Clears text attributes from a range.

Parameters

model	IN text model.
whichStrand	IN whether these are character or paragraph attributes.
startpos	IN start of clear range.
numchars	IN clear range length.
over	IN attributes to clear. Adjusts startpos & numchars to encompass EXACTLY ALL the characters within the intersecting paragraphs.

virtual DataWrapper<AttributeBossList> IAttributeStrand::GetLocalOverrides	(	TextIndex	position,
		int32 *	count,
		TextIndex *	runBegin = `nil`
	)		const

pure virtual

Returns: list of attributes applied at a position.

Parameters

position	IN text index to look at.
count	OUT length from position to end of paragraph run.
runBegin	OUT text index of start of paragraph run.

virtual UID IAttributeStrand::GetStyleUID	(	TextIndex	position,
		int32 *	count,
		TextIndex *	runBegin = `nil`
	)		const

pure virtual

Returns: UID of the style applied at a position

Parameters

position	IN text index to look at.
count	OUT length from 'position' to end of paragraph run.
runBegin	OUT text index of start of paragraph run.

virtual void IAttributeStrand::ParaRootStyleDiffs_ApplyAtPaste	(	TextIndex	start,
		int32	length,
		const UID &	charRootStyle,
		const UID &	paraRootStyle,
		const AttributeBossList *	diffAttrs,
		const AttributeBossList *	paraDest_SrcRootStyleDiffs,
		const ITextModel *	model
	)

pure virtual

For internal use only.

virtual void IAttributeStrand::RemoveRedundantOverrides	(	const ITextModel *	model,
		TextIndex	start,
		int32	len
	)

pure virtual

Remove overrides which are already applied through styles.

Parameters

model	IN text model.
start	IN start of remove range.
numchars	IN remove range length.

virtual void IAttributeStrand::ResetWithNoUndo	(	const ITextModel *	model,
		TextIndex	start,
		int32	length,
		UID	toStyle
	)

pure virtual

For internal use only.

virtual void IAttributeStrand::StoryThreadStyleDiffs_ApplyAtPaste	(	TextIndex	start,
		int32	length,
		const UID &	charRootStyle,
		const UID &	paraRootStyle,
		const AttributeBossList *	diffAttrs,
		const AttributeBossList *	dest_SrcStoryThreadStyleDiffs,
		const ITextModel *	model
	)

pure virtual

For internal use only.

virtual void IAttributeStrand::UnhookParagraphStyle	(	const ITextModel *	model,
		TextIndex	start,
		int32	len,
		UID	rootStyle,
		UID	oldParagraphStyle,
		UID	storyThreadStyle
	)

pure virtual

Remove reference to paragraph style but leave its effect in the form of overrides.

Parameters

model	IN text model.
start	IN start of unhook range.
len	IN unhook range length.
rootStyle	IN root style UID.
oldParagraphStyle	IN paragraph style to unhook.
