DAnCE: CIAO::NodeApplicationManager

CIAO::NodeApplicationManager_Impl::NodeApplicationManager_Impl	(	CORBA::ORB_ptr	o,
		PortableServer::POA_ptr	p,
		bool	is_multi_threaded
	)

Constructor.

CIAO::NodeApplicationManager_Impl::~NodeApplicationManager_Impl ( void ) [protected, virtual]

Destructor.

PortableServer::ObjectId CIAO::NodeApplicationManager_Impl::init	(	const char *	nodeapp_location,
		const char *	nodeapp_options,
		const CORBA::ULong	delay,
		const Deployment::DeploymentPlan &	plan,
		const PortableServer::POA_ptr	callback_poa,
		NodeManager_Impl_Base *	nm
	)			`[virtual]`

A factory operation to create NodeApplicationManager interface, and return the object reference. Initialize the NodeApplicationManager. The current implementation of CIAO_NodeApplicationManager can only activate CIAO's own NodeApplication processes. You should specify the location (pathname) of the NodeApplication and the delay. CIAO_NodeApplicationManager should wait (in second) for NodeApplication to call back.

Parameters:

	nodeapp_location	A null-termiated char * string pointing to the pathname of a NodeApplication executable.
	nodeapp_options	A null-terminated char * string containing command line options to be passed to the NodeApplication.
	delay	instructs how long (in second) a CIAO_NodeApplicationManager should wait for a newly spawned NodeApplication to pass back its IOR.
	plan	has all the information needed for the NodeAppManager to construct the application locally. Note, this includes the properties of the NodeApplication. For example, ORB config options etc.
	callback_poa	contains child poa created for the callback interface.

nm Pointer to the NodeManager_Impl servant object

Returns:: NodeApplicationManager_ptr.

Implements CIAO::NodeApplicationManager_Impl_Base.

Deployment::NodeApplication_ptr CIAO::NodeApplicationManager_Impl::create_node_application ( const ACE_CString & options ) [protected, virtual]

Internal help function to create new NodeApplicationProcess.

Implements CIAO::NodeApplicationManager_Impl_Base.

Deployment::NodeApplication_ptr CIAO::NodeApplicationManager_Impl::single_threaded_wait_for_callback	(	CIAO::NodeApplication_Callback_Impl *	cb_servant,
		ACE_Time_Value &	timeout
	)			`[protected]`

This method is only applicable when our program is configured as singled threaded . Internally it uses a <perform_work> blocking call to wait for NA object to call back

Deployment::NodeApplication_ptr CIAO::NodeApplicationManager_Impl::multi_threaded_wait_for_callback	(	CIAO::NodeApplication_Callback_Impl *	cb_servant,
		ACE_Time_Value &	timeout
	)			`[protected]`

This method is only applicable when our program is configured as multiple threaded. Internally it waits on a conditional variable that could be modified by the callback servant which runs in another thread

void CIAO::NodeApplicationManager_Impl::push_component_info ( pid_t process_id ) [protected]

pushes component info to the NodeManager

push_component_info

Parameters:

process_id

The id of the process of NodeApplication

NAM_Handler CIAO::NodeApplicationManager_Impl::child_handler_ [protected]

The signal handler.

bool CIAO::NodeApplicationManager_Impl::is_multi_threaded_ [private]

Whether we run ourselves in multi threaded configuration or not By default, we run in single threaded configuration.
