Member Function Documentation

◆ adaptStartOfLine()

void clang::format::BreakableLineCommentSection::adaptStartOfLine	(	unsigned	LineIndex,
		WhitespaceManager &	Whitespaces
	)		const

overridevirtual

Replaces the whitespace between LineIndex-1 and LineIndex.

Reimplemented from clang::format::BreakableToken.

References clang::format::BreakableComment::Content, clang::format::BreakableComment::ContentColumn, clang::format::BreakableComment::Lines, clang::format::BreakableComment::tokenAt(), and clang::format::BreakableComment::Tokens.

◆ getContentStartColumn()

unsigned clang::format::BreakableLineCommentSection::getContentStartColumn	(	unsigned	LineIndex,
		bool	Break
	)		const

overridevirtual

Returns the column at which content in line LineIndex starts, assuming no reflow.

If Break is true, returns the column at which the line should start after the line break. If Break is false, returns the column at which the line itself will start.

Implements clang::format::BreakableToken.

◆ getRangeLength()

unsigned clang::format::BreakableLineCommentSection::getRangeLength	(	unsigned	LineIndex,
		unsigned	Offset,
		StringRef::size_type	Length,
		unsigned	StartColumn
	)		const

overridevirtual

Returns the number of columns required to format the text in the byte range [Offset, Offset + Length).

Offset is the byte offset from the start of the content of the line at LineIndex.

StartColumn is the column at which the text starts in the formatted file, needed to compute tab stops correctly.

Implements clang::format::BreakableToken.

◆ getReflowSplit()

BreakableComment::Split clang::format::BreakableLineCommentSection::getReflowSplit	(	unsigned	LineIndex,
		const llvm::Regex &	CommentPragmasRegex
	)		const

overridevirtual

Returns a whitespace range (offset, length) of the content at LineIndex such that the content of that line is reflown to the end of the previous one.

Returning (StringRef::npos, 0) indicates reflowing is not possible.

The range will include any whitespace preceding the specified line's content.

If the split is not contained within one token, for example when reflowing line comments, returns (0, <length>).
