Synopsis

url_base& set_host_ipv4( const ipv4_address& addr);

Declared in file <src/url_base.cpp> at line 805

Description

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

Example

assert( url("http://www.example.com").set_host_ipv4( 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.

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
