Detailed Description
The QHostAddress class provides an IP address.
This class contains an IP address in a platform- and protocol-independent
manner. That is, it'll store the address in a way you can access easily on
any platform, and it'll store both IPv4 and IPv6 addresses.
QHostAddress is normally used with the classes QSocket, QServerSocket and
QSocketDevice to set up a server or to connect to a host.
See also QSocket, QServerSocket and QSocketDevice.
Member Function Documentation
QHostAddress::QHostAddress ()
Creates a socket address object with the IP address 0.0.0.0.
QHostAddress::QHostAddress ( Q_UINT32 ip4Addr )
Creates a socket address object for the IPv4 address ip4Addr.
QHostAddress::QHostAddress ( Q_UINT8 * ip6Addr )
Creates a socket address object with a specified IPv6 address.
ip6Addr must be a 16 byte array in network byte order (high-order byte
first)
QHostAddress::QHostAddress ( const QHostAddress & address )
Creates a copy of address.
QHostAddress::~QHostAddress () [virtual]
Destroys the socket address object.
Q_UINT32 QHostAddress::ip4Addr () const
Returns the IPv4 address as a number.
For example, if the address is 127.0.0.1, the returned value is
2130706433 (hex: 7f000001).
This value is only valid when isIp4Addr() returns TRUE.
See also toString().
bool QHostAddress::isIp4Addr () const
Return true if the host address represents a IPv4 address.
Assigns another socket address object address to this object and
returns a reference to this object.
bool QHostAddress::operator== ( const QHostAddress & other ) const
Returns TRUE if this socket address is identical to other, or FALSE
if they are different.
void QHostAddress::setAddress ( Q_UINT32 ip4Addr )
Set a IPv4 address specified by ip4Addr.
void QHostAddress::setAddress ( Q_UINT8 * ip6Addr )
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
Set a IPv6 address specified by ip6Addr.
ip6Addr must be a 16 byte array in network byte order (high-order byte
first)
bool QHostAddress::setAddress ( const QString & address )
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
Sets the IPv4 or IPv6 address specified by the string representation
address (e.g. "127.0.0.1").
If this function is not able to parse the address it will return FALSE and
the address is not changed.
QString QHostAddress::toString () const
Returns the address as a string.
For example, if the address is the IPv4 address 127.0.0.1, the
returned string is "127.0.0.1".
See also ip4Addr().
