boost::urls::string_token::arg
Base class for string tokens, and algorithm parameters
Synopsis
Declared in <boost/url/grammar/string_token.hpp>
struct arg;
Description
This abstract interface provides a means for an algorithm to generically obtain a modifiable, contiguous character buffer of prescribed size. As the author of an algorithm simply declare an rvalue reference as a parameter type.
Instances of this type are intended only to be used once and then destroyed.
The declared function accepts any
temporary instance of arg
to be
used for writing:
void algorithm( string_token::arg&& dest );
To implement the interface for your type or use-case, derive from the class and implement the prepare function.
