tigase.xmpp.JID

All Implemented Interfaces:

Comparable<JID>

public final class JID
extends Object
implements Comparable<JID>

The class defines an instance of a single XMPP JID identifier. When the object is created all parameters are checked and processed through the stringprep. An exception is thrown in case of a stringprep processing error. Created: Dec 28, 2009 10:48:04 PM

Method Detail

jidInstance

public static JID jidInstance(BareJID bareJid,
              String p_resource)
                       throws TigaseStringprepException

Constructs a new JID instance using given BareJID instance as user bare JID and String instance as a resource part.

As the BareJID instances are immutable the constructor doesn't create a copy of the given BareJID, instead it saves the reference to a given object.
The resourve parameter is parsed, checked and run through the stringprep processing. In case of stringprep error, an exception is thrown.

Parameters:

bareJid - is a BareJID instance used to create the JID instance.

p_resource - is a String instance representing JID's resource part.

Returns:

JID class instance.

Throws:

TigaseStringprepException - exception if there was an error during stringprep processing.

jidInstance

public static JID jidInstance(BareJID bareJid)

Creates a new JID instance using given BareJID instance as a parameter. The resource part is set to null.
As the BareJID instances are immutable the constructor doesn't create a copy of the given BareJID, instead it saves the reference to a given object.

Parameters:

bareJid - is a BareJID instance used to create the JID instance.

Returns:

JID class instance.

jidInstance

public static JID jidInstance(String jid)
                       throws TigaseStringprepException

Constructs a new JID instance using a JID parameter given as a String instance. The parameter is parsed, checked and run through stringprep processing. An exception is thrown if there is an error while the JID is checked.

Parameters:

jid - a JID parameter given as a String instance.

Returns:

JID class instance.

Throws:

TigaseStringprepException - exception if there was an error during stringprep processing.

jidInstance

public static JID jidInstance(String localpart,
              String domain,
              String resource)
                       throws TigaseStringprepException

Constructs a new JID instance using given String parameters.

All the String parameters are parsed, checked and run through the stringprep processing. In case of stringprep error, an exception is thrown.

Parameters:

localpart - is a String instance representing JID's localpart (nickname) part.

domain - is a String instance representing JID's domain part.

resource - is a String instance representing JID's resource part.

Returns:

JID class instance.

Throws:

TigaseStringprepException - exception if there was an error during stringprep processing.

jidInstanceNS

public static JID jidInstanceNS(BareJID bareJid,
                String p_resource)

Constructs a new JID instance using given BareJID instance as user bare JID and String instance as a resource part. Note, this method does not perform stringprep processing on input parameters.

As the BareJID instances are immutable the constructor doesn't create a copy of the given BareJID, instead it saves the reference to a given object.

Parameters:

bareJid - is a BareJID instance used to create the JID instance.

p_resource - is a String instance representing JID's resource part.

Returns:

JID class instance.

jidInstanceNS

public static JID jidInstanceNS(String jid)

Constructs a new JID instance using a JID parameter given as a String instance. Note, this method does not perform stringprep processing on input parameters and it returns null if null is passed as parameter. The method does not throw NullPointerException if the String passed is null.

Parameters:

jid - a JID parameter given as a String instance.

Returns:

JID class instance or null.

jidInstanceNS

public static JID jidInstanceNS(String localpart,
                String domain,
                String resource)

Constructs a new JID instance using given String parameters. Note, this method does not perform stringprep processing on input parameters.

Parameters:

localpart - is a String instance representing JID's localpart (nickname) part.

domain - is a String instance representing JID's domain part.

resource - is a String instance representing JID's resource part.

Returns:

JID class instance.

compareTo

public int compareTo(JID o)

Method compares the JID instance with a given object. The implementation fulfills the specification contract and returns a value as you would expect from the call:

 jid_1.toString().compareTo(jid_2.toString())
 

Specified by:

compareTo in interface Comparable<JID>

Parameters:

o - is a JID instance to compare to.

Returns:

an integer value which is a result of comparing the two objects.

copyWithResource

public JID copyWithResource(String resource)
                     throws TigaseStringprepException

The method returns a copy of the JID instance with a different resource part given as a parameter.

Parameters:

resource - is a String instance representing JID's new resource part.

Returns:

a new instance of the JID class with a new resource part.

Throws:

TigaseStringprepException - if resource stringprep processing fails.

copyWithResourceNS

public JID copyWithResourceNS(String resource)

The method returns a copy of the JID instance with a different resource part given as a parameter.

Parameters:

resource - is a String instance representing JID's new resource part.

Returns:

a new instance of the JID class with a new resource part.

copyWithoutResource

public JID copyWithoutResource()

The method returns a copy of the JID instance with removed resource part. The result is similar to the BareJID instance, however there are APIs which require JID object to use.

Returns:

a new instance of the JID class with removed resource part.

equals

public boolean equals(Object b)

Method compares whether this JID instance represents the same user JID as the one given in parameter. It returns true of all: the localpart (nickname), domain part, and the resource part are the same for both objects.

Overrides:

equals in class Object

Parameters:

b - is a JID object to which the instance is compared.

Returns:

a boolean value of true if both instances represent the same JID and false otherwise.

getBareJID

public BareJID getBareJID()

Method returns BareJID instance for this JID.

Returns:

a BareJID instance.

getDomain

public String getDomain()

Method returns a domain part of the JID instance.

Returns:

a domain part of the JID instance.

getLocalpart

public String getLocalpart()

Method a localpart (nickname) of the JID instance.

Returns:

a localpart (nickname) of the JID instance.

getResource

public String getResource()

Method a resource part of the JID instance.

Returns:

a resource part of the JID instance.

hashCode

public int hashCode()

Method returns a hash code calculated for the JID instance.

Overrides:

hashCode in class Object

Returns:

an object hash code.

toString

public String toString()

Method returns a String representation of the JID instance.

Overrides:

toString in class Object

Returns:

a String representation of the JID instance.
