InetAddress Class Reference

#include <coherence/net/InetAddress.hpp>

Inherits Object.

List of all members.


Detailed Description

InetAddress represents an IP address.
Author:

Public Types

typedef spec::Handle  Handle
  InetAddress Handle definition.
typedef spec::View  View
  InetAddress View definition.
typedef spec::Holder  Holder
  InetAddress Holder definition.

Public Member Functions

virtual String::View  getHostName () const
  Return the hostname associated with this address.
virtual String::View  getHostAddress () const
  Return the address in textual form.
virtual Array
< octet_t >::View 
getAddress () const
  Return the raw IP address, in network byte order, with the highest order byte stored at index zero.
virtual void  toStream (std::ostream &out) const
  Output a human-readable description of this Object to the given stream.

coherence::lang::operator<<(std::ostream, Object::View) is defined and will call into the toStream method, to output Objects. If a managed String object is desired, the COH_TO_STRING macro can be used to build up a String from streamable contents.

 Object::View vKey   = ...
 Object::View vValue = ...
 std::cout << vKey << " = " << vValue << std::endl;

 String::Handle hs = COH_TO_STRING(vKey << " = " << vValue);
Parameters:
out  the stream used to output the description

virtual bool  equals (Object::View that) const
 
virtual size32_t  hashCode () const
  Return a hash code value for the Object.

This method is supported for the benefit of hash-based containers.

The general contract of hashCode is:

  • Whenever it is invoked on the same Object more than once during an execution of an application, the hashCode method must consistently return the same value, provided no information used in equals comparisons on the object is modified. This value need not remain consistent from one execution of an application to another execution of the same application.
  • If two Objects are equal according to the equals method, then calling the hashCode method on each of the two Objects must produce the same value.
  • It is not required that if two Objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct results. However, the programmer should be aware that producing distinct results for unequal objects may improve the performance of hash-based containers.

The default implementation is identity based.

Returns:
a hash code value for this Object


Static Public Member Functions

static InetAddress::View  getLocalHost ()
  Return the InetAddress for the local machine.
static InetAddress::View  getByName (String::View vHost)
  Return the InetAddress for the specified machine name.

Protected Member Functions

  InetAddress (String::View vsHost, Array< octet_t >::View vaIP)
  Manually construct an InetAddress from a network byte ordered array.
  InetAddress (const InetAddress &)
  Copy Constructor.

Constructor & Destructor Documentation

InetAddress ( String::View  vsHost,
Array< octet_t >::View  vaIP  
) [protected]

Manually construct an InetAddress from a network byte ordered array.

It is recommended that the getByName() method be used in place of manual InetAddress construction.

Parameters:
vsName  the name of the host
vaIP  the array representation of the host's IP address.

Member Function Documentation

static InetAddress::View getLocalHost (  )  [static]

Return the InetAddress for the local machine.

Returns:
the local InetAddress.

static InetAddress::View getByName ( String::View  vHost  )  [static]

Return the InetAddress for the specified machine name.

Parameters:
vHost  the name or IP of the host to resolve
Returns:
the InetAddress for the specified machine name

virtual String::View getHostName (  )  const [virtual]

Return the hostname associated with this address.

Returns:
the hostname associated with this address

virtual String::View getHostAddress (  )  const [virtual]

Return the address in textual form.

Returns:
the address in textual form

virtual Array<octet_t>::View getAddress (  )  const [virtual]

Return the raw IP address, in network byte order, with the highest order byte stored at index zero.

Returns:
the raw IP address
