Detailed Description

The node observer interface.

Observers should implement this interface to receive information about the state of the IceGrid nodes.

◆ ice_id()

virtual::std::string IceGrid::NodeObserver::ice_id ( const ::Ice::Current & current ) const

override

Obtains a Slice type ID representing the most-derived interface supported by this object.

Parameters

current The Current object for the invocation.

Returns: A fully-scoped type ID.

◆ ice_ids()

virtual ::std::vector<::std::string > IceGrid::NodeObserver::ice_ids ( const ::Ice::Current & current ) const

override

Obtains a list of the Slice type IDs representing the interfaces supported by this object.

Parameters

current The Current object for the invocation.

Returns: A list of fully-scoped type IDs.

◆ ice_isA()

virtual bool IceGrid::NodeObserver::ice_isA	(	::std::string	id,
		const ::Ice::Current &	current ) const

overridevirtual

Determines whether this object supports an interface with the given Slice type ID.

Parameters

id	The fully-scoped Slice type ID.
current	The Current object for the invocation.

Returns: True if this object supports the interface, false, otherwise.

◆ ice_staticId()

const ::std::string & IceGrid::NodeObserver::ice_staticId ( )

static

Obtains the Slice type ID corresponding to this class.

Returns: A fully-scoped type ID.

◆ nodeDown()

virtual void IceGrid::NodeObserver::nodeDown	(	::std::string	name,
		const ::Ice::Current &	current )

pure virtual

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.

◆ nodeInit()

virtual void IceGrid::NodeObserver::nodeInit	(	NodeDynamicInfoSeq	nodes,
		const ::Ice::Current &	current )

pure virtual

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()

virtual void IceGrid::NodeObserver::nodeUp	(	NodeDynamicInfo	node,
		const ::Ice::Current &	current )

pure virtual

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.

◆ updateAdapter()

virtual void IceGrid::NodeObserver::updateAdapter	(	::std::string	node,
		AdapterDynamicInfo	updatedInfo,
		const ::Ice::Current &	current )

pure virtual

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.

◆ updateServer()

virtual void IceGrid::NodeObserver::updateServer	(	::std::string	node,
		ServerDynamicInfo	updatedInfo,
		const ::Ice::Current &	current )

pure virtual

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.
