Method Detail

nodeInit

void nodeInit(NodeDynamicInfo[] nodes,
              Ice.Current __current)

The nodeInit operation indicates the current state of nodes. It is called after the registration of an observer.

Parameters:

nodes - The current state of the nodes.

__current - The Current object for the invocation.

nodeUp

void nodeUp(NodeDynamicInfo node,
            Ice.Current __current)

The nodeUp operation is called to notify an observer that a node came up.

Parameters:

node - The node state.

__current - The Current object for the invocation.

nodeDown

void nodeDown(java.lang.String name,
              Ice.Current __current)

The nodeDown operation is called to notify an observer that a node went down.

Parameters:

name - The node name.

__current - The Current object for the invocation.

updateServer

void updateServer(java.lang.String node,
                  ServerDynamicInfo updatedInfo,
                  Ice.Current __current)

The updateServer operation is called to notify an observer that the state of a server changed.

Parameters:

node - The node hosting the server.

updatedInfo - The new server state.

__current - The Current object for the invocation.

updateAdapter

void updateAdapter(java.lang.String node,
                   AdapterDynamicInfo updatedInfo,
                   Ice.Current __current)

The updateAdapter operation is called to notify an observer that the state of an adapter changed.

Parameters:

node - The node hosting the adapter.

updatedInfo - The new adapter state.

__current - The Current object for the invocation.
