public void removeSubGroup(MockContactGroup subgroup)

Removes the specified contact group from the this group's subgroups.

Parameters:

findGroupParent

public MockContactGroup findGroupParent(MockContactGroup mockGroup)

Returns the group that is parent of the specified mockGroup or null if no parent was found.

Parameters:

Returns the Contact with the specified address or identifier.

Specified by:

getContact in interface ContactGroup

Parameters:

id - the addres or identifier of the Contact we are looking for.

Returns:

the Contact with the specified id or address.

getGroup

public ContactGroup getGroup(int index)

Returns the subgroup with the specified index.

Specified by:

getGroup in interface ContactGroup

Parameters:

index - the index of the ContactGroup to retrieve.

Returns:

the ContactGroup with the specified index.

getGroup

public ContactGroup getGroup(String groupName)

Returns the subgroup with the specified name.

Specified by:

getGroup in interface ContactGroup

Parameters:

groupName - the name of the ContactGroup to retrieve.

Returns:

the ContactGroup with the specified index.

getGroupName

public String getGroupName()

Returns the name of this group.

subgroups

public Iterator<ContactGroup> subgroups()

Returns an iterator over the sub groups that this ContactGroup contains.

Specified by:

subgroups in interface ContactGroup

Returns:

a java.util.Iterator over the ContactGroup children of this group (i.e. subgroups).

removeContact

public void removeContact(MockContact contact)

Removes the specified contact from this group.

Parameters:

contact - the MockContact to remove from this group

findContactByID

public MockContact findContactByID(String id)

Returns the contact with the specified id or null if no such contact exists.

Parameters:

id - the id of the contact we're looking for.

Returns:

MockContact

toString

public String toString()

Returns a String representation of this group and the contacts it contains (may turn out to be a relatively long string).

Overrides:

toString in class Object

Returns:

a String representing this group and its child contacts.

isPersistent

public boolean isPersistent()

Determines whether or not this contact group is being stored by the server. Non persistent contact groups exist for the sole purpose of containing non persistent contacts.

Specified by:

isPersistent in interface ContactGroup

Returns:

true if the contact group is persistent and false otherwise.

getPersistentData

public String getPersistentData()

Returns null as no persistent data is required and the contact address is sufficient for restoring the contact.

Specified by:

getPersistentData in interface ContactGroup

Returns:

null as no such data is needed.

isResolved

public boolean isResolved()

Determines whether or not this contact has been resolved against the server. Unresolved contacts are used when initially loading a contact list that has been stored in a local file until the presence operation set has managed to retrieve all the contact list from the server and has properly mapped contacts to their on-line buddies.

Specified by:

isResolved in interface ContactGroup

Returns:

true if the contact has been resolved (mapped against a buddy) and false otherwise.

setResolved

public void setResolved(boolean resolved)

Makes the group resolved or unresolved.

Parameters:

resolved - true to make the group resolved; false to make it unresolved

getUID

public String getUID()

Returns a String that uniquely represnets the group inside the current protocol. The string MUST be persistent (it must not change across connections or runs of the application). In many cases (Jabber, ICQ) the string may match the name of the group as these protocols only allow a single level of contact groups and there is no danger of having the same name twice in the same contact list. Other protocols (no examples come to mind but that doesn't bother me ;) ) may be supporting mutilple levels of grooups so it might be possible for group A and group B to both contain groups named C. In such cases the implementation must find a way to return a unique identifier in this method and this UID should never change for a given group.

Specified by:

getUID in interface ContactGroup

Returns:

a String representing this group in a unique and persistent way.

createNameFromUID

static String createNameFromUID(String uid)

Ugly but tricky conversion method.

Parameters:

uid - the uid we'd like to get a name from

Returns:

the name of the group with the specified uid.

equals

public boolean equals(Object obj)

Indicates whether some other object is "equal to" this one which in terms of contact groups translates to having the equal names and matching subgroups and child contacts. The resolved status of contactgroups and contacts is deliberately ignored so that groups and/or contacts would be assumed equal even if it differs.

Overrides:

equals in class Object

Parameters:

obj - the reference object with which to compare.

Returns:

true if this contact group has the equal child contacts and subgroups to those of the obj argument.
