Detailed Description

The QLatin1Literal class provides a thin wrapper around string literals used in source code.

Warning

This function is not part of the public interface.

Note

This class or function is reentrant.

Since

4.6

Unlike QLatin1String, a QLatin1Literal can retrieve its size without iterating over the literal.

The main use of QLatin1Literal is in conjunction with QStringBuilder to reduce the number of reallocations needed to build up a string from smaller chunks.
