Replaces the current object with a host and port.

Synopsis

void
emplace_host_and_port(
    std::string hostname,
    unsigned short port = default_port);

Description

Destroys the current contained object and constructs a new host and port from the passed components. This function can change the underlying type of object held by *this.

The constructed object has this->type() == address_type::host_and_port, this->hostname() == hostname and this->port() == port.

An empty hostname is equivalent to localhost.

Exception safety

Basic guarantee. Memory allocations may throw.

Object lifetimes

Invalidates views pointing into *this.
