Member Function Documentation

static unsigned int decaf::net::InetAddress::bytesToInt	(	const unsigned char *	bytes,
		int	start
	)

staticprotected

Converts the bytes in an address array to an int starting from the value start treating the start value as the high order byte.

Parameters

bytes	The array of bytes to convert to an int.
start	The index in the array to treat as the high order byte.

Returns: an unsigned int that represents the address value.

virtual InetAddress* decaf::net::InetAddress::clone ( ) const

virtual

Returns a newly allocated copy of this InetAddress.

The caller owns the resulting copy and must delete it.

Returns: a new InetAddress instance that is a copy of this one, caller owns.

Reimplemented in decaf::net::Inet4Address, and decaf::net::Inet6Address.

virtual decaf::lang::ArrayPointer<unsigned char> decaf::net::InetAddress::getAddress ( ) const

virtual

Returns the Raw IP address in Network byte order.

The returned address is a copy of the bytes contained in this InetAddress.

Returns: and ArrayPointer containing the raw bytes of the network address.

static InetAddress decaf::net::InetAddress::getAnyAddress ( )

staticprotected

static InetAddress decaf::net::InetAddress::getByAddress	(	const unsigned char *	bytes,
		int	numBytes
	)

static

Given a raw IP Address in byte array form, create and return a new InetAddress instance.

An IPV4 address must be only four bytes in length and an IPV6 address must be 16 bytes in length.

Returns: a copy of an InetAddress that represents the given byte array address.

Exceptions

UnknownHostException if the address array length is invalid.

static InetAddress decaf::net::InetAddress::getByAddress	(	const std::string &	hostname,
		const unsigned char *	bytes,
		int	numBytes
	)

static

Given a host name and IPAddress return a new InetAddress.

There is no name service checking or address validation done on the provided host name. The host name can either be machine name or the text based representation of the IP Address.

An IPV4 address must be only four bytes in length and an IPV6 address must be 16 bytes in length.

Returns: a copy of an InetAddress that represents the given byte array address.

Exceptions

UnknownHostException if the address array length is invalid.

virtual std::string decaf::net::InetAddress::getHostAddress ( ) const

virtual

Returns a textual representation of the IP Address.

Returns: the string form of the IP Address.

virtual std::string decaf::net::InetAddress::getHostName ( ) const

virtual

Get the host name associated with this InetAddress instance.

If a host name was set upon construction then that value is returned, otherwise a reverse name lookup with be performed to attempt to get the host name associated with the set IP Address. If the host name cannot be resolved the textual representation of the IP Address is returned instead.

Returns: the name of the host associated with this set IP Address.

static InetAddress decaf::net::InetAddress::getLocalHost ( )

static

Gets an InetAddress that is the local host address.

If the localhost value cannot be resolved than the InetAddress for Loopback is returned.

Returns: a new InetAddress object that contains the local host address.

Exceptions

UnknownHostException if the address for local host is not found.

static InetAddress decaf::net::InetAddress::getLoopbackAddress ( )

Check if this InetAddress is Multicast and has Site Local scope.

Returns: true if the address is Multicast and has Site Local scope.

Reimplemented in decaf::net::Inet4Address.

virtual bool decaf::net::InetAddress::isMulticastAddress ( ) const

inlinevirtual

Check if this InetAddress is a valid Multicast address.

Returns: true if the address is a Multicast address.

Reimplemented in decaf::net::Inet4Address.

virtual std::string decaf::net::InetAddress::toString ( ) const

virtual

Returns a string representation of the InetAddress in the form 'hostname / ipaddress'.

If the hostname is not resolved than it appears as empty.

Returns: string value of this InetAddress.
