示例1: join
JSValue JSStringJoiner::join(ExecState* exec)
{
if (!m_isValid)
return throwOutOfMemoryError(exec);
if (!m_strings.size())
return jsEmptyString(exec);
Checked<size_t, RecordOverflow> separatorLength = m_separator.length();
// FIXME: add special cases of joinStrings() for (separatorLength == 0) and (separatorLength == 1).
ASSERT(m_strings.size() > 0);
Checked<size_t, RecordOverflow> totalSeparactorsLength = separatorLength * (m_strings.size() - 1);
Checked<size_t, RecordOverflow> outputStringSize = totalSeparactorsLength + m_accumulatedStringsLength;
size_t finalSize;
if (outputStringSize.safeGet(finalSize) == CheckedState::DidOverflow)
return throwOutOfMemoryError(exec);
if (!outputStringSize)
