Detailed Description

template<typename Impl, typename Result>
class fmt::ArgVisitor< Impl, Result >

\rst An argument visitor based on the curiously recurring template pattern <http://en.wikipedia.org/wiki/Curiously_recurring_template_pattern>_.

To use ~fmt::ArgVisitor define a subclass that implements some or all of the visit methods with the same signatures as the methods in ~fmt::ArgVisitor, for example, ~fmtArgVisitor::visit_int(). Pass the subclass as the Impl template parameter. Then calling ~fmtArgVisitor::visit for some argument will dispatch to a visit method specific to the argument type. For example, if the argument type is double then the ~fmtArgVisitor::visit_double() method of a subclass will be called. If the subclass doesn't contain a method with this signature, then a corresponding method of ~fmt::ArgVisitor will be called.

Example**::

class MyArgVisitor : public fmt::ArgVisitor<MyArgVisitor, void> { public: void visit_int(int value) { fmt::print("{}", value); } void visit_double(double value) { fmt::print("{}", value ); } }; \endrst
