\doxysubsection{Detailed Description}
The constants in this group can be combined with \mbox{\hyperlink{operators_bitwise_or_operator}{binary or}} to give regular expression options for the \mbox{\hyperlink{group__string__functions_gab17427299ed00ee52d90beadc55ba608}{regex()}}, \mbox{\hyperlink{group__string__functions_gaaf6eccd667d478b31ce20cde7556491f}{regex\+\_\+subst()}}, and \mbox{\hyperlink{group__string__functions_ga3461a37dbd3d51bc03e58b85daae2466}{regex\+\_\+extract()}} functions.
