fragment

Return the fragment

Synopsis


                template<
    class StringToken = return_string>
StringToken::result_type
fragment(
    StringToken&& token);

Declared in file <boost/url/url_view_base.hpp> at line 2149

Description

This function calculates the fragment of the url, with percent escapes decoded and without the leading pound sign ('#') whose presence indicates that the url contains a fragment.

This function accepts an optional StringToken parameter which controls the return type and behavior of the function:

When called with no arguments, the return type of the function is `std::string`. Otherwise

When called with a string token, the behavior and return type of the function depends on the type of string token being passed.

Example


assert( url_view( "http://www.example.com/index.htm#a%2D1" ).fragment() == "a-1" );

Complexity

Linear in `this->fragment().size()`.

Exception Safety

Calls to allocate may throw. String tokens may throw exceptions.

BNF


fragment        = *( pchar / "/" / "?" )

fragment-part   = [ "#" fragment ]
