Enum Constants

Enum Constant	Description
BOTH	User and contact are subscribed to each other (two-way); this is reflected in the user's roster by subscription='both'.

FROM_PENDING_OUT	Contact is subscribed to user, and user has sent contact a subscription request but contact has not replied yet; this is reflected in the user's roster by subscription='from' and ask='subscribe'.
NONE	Contact and user are not subscribed to each other, and neither has requested a subscription from the other; this is reflected in the user's roster by subscription='none'.
NONE_PENDING_IN	Contact and user are not subscribed to each other, and contact has sent user a subscription request but user has not replied yet.
NONE_PENDING_OUT	Contact and user are not subscribed to each other, and user has sent contact a subscription request but contact has not replied yet; this is reflected in the user's roster by subscription='none' and ask='subscribe'.
NONE_PENDING_OUT_IN	Contact and user are not subscribed to each other, contact has sent user a subscription request but user has not replied yet, and user has sent contact a subscription request but contact has not replied yet; this is reflected in the user's roster by subscription='none' and ask='subscribe'.
TO	User is subscribed to contact (one-way); this is reflected in the user's roster by subscription='to'.
TO_PENDING_IN	User is subscribed to contact, and contact has sent user a subscription request but user has not replied yet; this is reflected in the user's roster by subscription='to'.

Enum Constant Detail

NONE

public static final DefinedState NONE

Contact and user are not subscribed to each other, and neither has requested a subscription from the other; this is reflected in the user's roster by subscription='none'.

NONE_PENDING_OUT

public static final DefinedState NONE_PENDING_OUT

Contact and user are not subscribed to each other, and user has sent contact a subscription request but contact has not replied yet; this is reflected in the user's roster by subscription='none' and ask='subscribe'.

NONE_PENDING_IN

public static final DefinedState NONE_PENDING_IN

Contact and user are not subscribed to each other, and contact has sent user a subscription request but user has not replied yet. This state might or might not be reflected in the user's roster, as follows: if the user has created a roster item for the contact then the server MUST maintain that roster item and also note the existence of the inbound presence subscription request, whereas if the user has not created a roster item for the contact then the user's server MUST note the existence of the inbound presence subscription request but MUST NOT create a roster item for the contact (instead, the server MUST wait until the user has approved the subscription request before adding the contact to the user's roster).

NONE_PENDING_OUT_IN

public static final DefinedState NONE_PENDING_OUT_IN

Contact and user are not subscribed to each other, contact has sent user a subscription request but user has not replied yet, and user has sent contact a subscription request but contact has not replied yet; this is reflected in the user's roster by subscription='none' and ask='subscribe'.

TO

public static final DefinedState TO

User is subscribed to contact (one-way); this is reflected in the user's roster by subscription='to'.

TO_PENDING_IN

public static final DefinedState TO_PENDING_IN

User is subscribed to contact, and contact has sent user a subscription request but user has not replied yet; this is reflected in the user's roster by subscription='to'.

FROM

public static final DefinedState FROM

Contact is subscribed to user (one-way); this is reflected in the user's roster by subscription='from'.

FROM_PENDING_OUT

public static final DefinedState FROM_PENDING_OUT

Contact is subscribed to user, and user has sent contact a subscription request but contact has not replied yet; this is reflected in the user's roster by subscription='from' and ask='subscribe'.

BOTH

public static final DefinedState BOTH

User and contact are subscribed to each other (two-way); this is reflected in the user's roster by subscription='both'.

Method Detail

values

public static DefinedState[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (DefinedState c : DefinedState.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static DefinedState valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

valueOf

public static DefinedState valueOf(SubscriptionState subscriptionState)

Returns a defined subscription state from an existing subscription state, e.g. a RosterItem.

Parameters:

subscriptionState - The existing subscription state.

Returns:

The defined subscription state. Never null.

getSubscription

public final SubscriptionState.Subscription getSubscription()

Description copied from interface: SubscriptionState

Gets the primary subscription state. It may be one of SubscriptionState.Subscription.NONE, SubscriptionState.Subscription.TO, SubscriptionState.Subscription.FROM or SubscriptionState.Subscription.BOTH.

Specified by:

getSubscription in interface SubscriptionState

Specified by:

isPendingOut in interface SubscriptionState

Returns:

If the state is pending out.

isPendingIn

public final boolean isPendingIn()

Description copied from interface: SubscriptionState

If the presence subscription is pending in from a user's perspective. The contact has sent user a subscription request but user has not replied yet.
