\class QLatin1Literal
\reentrant
\since 4.6
\brief The QLatin1Literal class provides a thin wrapper around string
literals used in source code.
\ingroup tools
\ingroup shared
\ingroup text
\mainclass
Unlike \c QLatin1String, a \c QLatin1Literal can retrieve its size
without iterating over the literal.
The main use of \c QLatin1Literal is in conjunction with \c QStringBuilder
to reduce the number of reallocations needed to build up a string from
smaller chunks.
\sa QStringBuilder, QLatin1String, QString, QStringRef
*/
/*! \fn int QLatin1Literal::size() const
Returns the number of characters in the literal \e{excluding} the trailing
NULL char.
*/
/*! \fn QLatin1Literal::QLatin1Literal(const char(&string)[N])
Constructs a new literal from the given \a string.
*/
/*! \fn char *QLatin1Literal::data() const
Returns a pointer to the first character of the string literal.
The string literal is terminated by a NUL character.
*/
/*! \fn QLatin1Literal::operator QString() const
Converts the \c QLatin1Literal into a \c QString object.

\class QStringBuilder
\reentrant
\since 4.6
\brief The QStringBuilder class is a template class that provides a facility to build
up QStrings from smaller chunks.
\ingroup tools
\ingroup shared
\ingroup text
\mainclass
When creating strings from smaller chunks, typically \c QString::operator+()
is used, resulting in \e{n - 1} reallocations when operating on \e{n} chunks.
QStringBuilder uses expression templates to collect the individual parts,
compute the total size, allocate memory for the resulting QString object,
and copy the contents of the chunks into the result.
The QStringBuilder class is not to be used explicitly in user code.
Instances of the class are created as return values of the operator%()
function, acting on objects of type \c QString, \c QLatin1String,
\c QLatin1Literal, \c \QStringRef, \c QChar, \c QCharRef,
\c QLatin1Char, and \c char.
Concatenating strings with operator%() generally yields better
performance then using \c QString::operator+() on the same chunks
if there are three or more of them, and performs equally well in other
cases.
\sa QLatin1Literal, QString
*/
/* \fn template <class A, class B> QStringBuilder<A, B> operator%(const A &a, const B &b)
Returns a \c QStringBuilder object that is converted to a QString object
when assigned to a variable of QString type or passed to a function that
takes a QString parameter.
This function is usable with arguments of type \c QString,
\c QLatin1String, \c QLatin1Literal, \c QStringRef,
\c QChar, \c QCharRef, \c QLatin1Char, and \c char.
