Set the host to an address.

Synopsis

url_base&
set_host_address(
    ipv4_address const& addr);

Description

The host is set to the specified IPv4 address. The host type will be host_type::ipv4.

Example

assert( url("http://www.example.com").set_host_address( ipv4_address( "127.0.0.1" ) ).buffer() == "http://127.0.0.1" );

Complexity

Linear in this->size().

Postconditions

this->has_authority() == true && this->host_ipv4_address() == addr && this->host_type() == host_type::ipv4

Exception Safety

Strong guarantee. Calls to allocate may throw.

Parameters

BNF

IPv4address = dec-octet "." dec-octet "." dec-octet "." dec-octet

dec-octet   = DIGIT                 ; 0-9
            / %x31-39 DIGIT         ; 10-99
            / "1" 2DIGIT            ; 100-199
            / "2" %x30-34 DIGIT     ; 200-249
            / "25" %x30-35          ; 250-255
