Function url_base::set_host_ipv6

Set the host to an address

Synopsis

Declared in header <boost/url/url_base.hpp>

url_base&
set_host_ipv6(const ipv6_address& addr);

Description

The host is set to the specified IPv6 address. The host type is host_type::ipv6 .

Example

assert( url().set_host_ipv6( ipv6_address( "1::6:c0a8:1" ) ).authority().buffer() == "[1::6:c0a8:1]" );

Postconditions

this->has_authority() == true && this->host_ipv6_address() == addr && this->host_type() == host_type::ipv6

Complexity

Linear in this->size().

Exception Safety

Strong guarantee. Calls to allocate may throw.
