Offers state information about an IP address.

This protocol encodes the underlying object’s lifetime in both directions; the underlying object is alive iff both ends of the protocol are open (unless [AddressStateProvider.Detach] has been called). That is:

• Closing the client end causes the object to be destroyed.
• Observing a closure of the server end indicates the object no longer exists.

Variants

UpdateAddressProperties

Push an update when the address properties change.

The client pushes updates on address properties changes, such as the address becoming deprecated, or the preferred and valid lifetimes being updated as a result of extending the address’ lifetime. The server is expected to cache address properties.

If address_properties contains invalid property values, the address is removed and [AddressRemovalReason.INVALID_PROPERTIES] is issued.

• request address_properties the updated properties of the address.

Fields

address_properties: AddressProperties

responder: AddressStateProviderUpdateAddressPropertiesResponder

WatchAddressAssignmentState

Hanging get for address assignment state.

The server does not keep a queue of assignment states, it returns the latest state if it differs from the last one observed.

The first call will always immediately return the current assignment state. Subsequent calls will block until the returned value differs from the last observed value.

It is invalid to call this method while a previous call is pending. Doing so will cause the server end of the protocol to be closed.

• response assignment_state the assignment state of the address.

Fields

responder: AddressStateProviderWatchAddressAssignmentStateResponder

Detach

Detaches the address’ lifetime from the client end of the protocol.

The client end of the protocol can be closed immediately after calling this method, and the address will not be removed.

Fields

control_handle: AddressStateProviderControlHandle

Remove

Removes the address.

The server end of the protocol is closed after address removal has completed, and the USER_REMOVED OnAddressRemoved event is sent.

Fields

control_handle: AddressStateProviderControlHandle
