Member Function Documentation

◆ getContentStartColumn()

unsigned clang::format::BreakableStringLiteralUsingOperators::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.

Reimplemented from clang::format::BreakableStringLiteral.

◆ getRemainingLength()

unsigned clang::format::BreakableStringLiteralUsingOperators::getRemainingLength ( unsigned  LineIndex,
unsigned  Offset,
unsigned  StartColumn 
) const
overridevirtual

Returns the number of columns required to format the text following the byte Offset in the line LineIndex, including potentially unbreakable sequences of tokens following after the end of the token.

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.

For breakable tokens that never use extra space at the end of a line, this is equivalent to getRangeLength with a Length of StringRef::npos.

Reimplemented from clang::format::BreakableStringLiteral.

◆ updateAfterBroken()

void clang::format::BreakableStringLiteralUsingOperators::updateAfterBroken ( WhitespaceManager Whitespaces) const

Adds replacements that are needed when the token is broken.

Such as wrapping a JavaScript string in parentheses after it gets broken with plus signs.
