MACIHelper class is a class helping to handle commonly used operations.

Author:

Matej Sekoranja, Jozef Stefan Institute, Slovenia

Version:

static ACE_CString maci::MACIHelper::extractHostnameFromCorbaloc (const ACE_TCHAR * corbaloc) [static] Extract hostname from corbaloc address.

Parameters:

corbaloc corbaloc address

Returns:

hostname or empty string on failure

static ACE_CString maci::MACIHelper::getManagerHostname (int argc, ACE_TCHAR ** argv) [static] getManagerHostname is a method helping to retrieve Manager’s hostname. The Manager hostame is extraced using the first valid of the following options: # Command line option -m or -managerReference # ManagerReference value in configuration database # Environment variable MANAGER_REFERENCE # hostname

Parameters:

argv command line parameter count
argc command line array of strings

Returns:

Manager’s hostname

static CORBA::Repository_ptr maci::MACIHelper::resolveInterfaceRepository (CORBA::ORB_ptr orb, const ACE_TCHAR * reference, int retries = 3, unsigned int secTimeout = 0) [static] resolveInterfaceRepository method resolve given stringified CORBA reference to the InterfaceRepository.

Parameters:

orb CORBA ORB
reference stringified CORBA reference to the InterfaceRepository
retries number of retries resolving InterfaceRepository reference, <= 0 means infinite
secTimeout timeout expressed in seconds, == 0 means inifinite (dt between retries is 3secs)

Returns:

CORBA reference to the InterfaceRepository or CORBA::Object::_nil()

static CORBA::Repository_ptr maci::MACIHelper::resolveInterfaceRepository (CORBA::ORB_ptr orb, maci::Manager_ptr manager, int argc, ACE_TCHAR ** argv, int retries = 3, unsigned int secTimeout = 0) [static] resolveInterfaceRepository method is a method helping to resolve CORBA InterfaceRepository’s reference. The InterfaceRepository reference is defined by the first valid of the following options: # Command line option -ORBInitRef InterfaceRepository=<corbaloc reference>=’’> (e.g. corbaloc::te1.hq.eso.org:xxxx) using CORBA::ORB::resolve_initial_references(’InterfaceRepository’), ORB has to be already initialized with the command line # Manager get_service(’InterfaceRepository’) # corbaloc::<manager’s hostname>:xxxx/NameService # corbaloc::<hostname>:xxxx/NameService

Parameters:

orb CORBA ORB
manager Manager’s reference.
argv command line parameter count
argc command line array of strings
retries number of retries resolving NameService reference, <= 0 means infinite
secTimeout timeout expressed in seconds, == 0 means inifinite (dt between retries is 3secs).

Returns:

CORBA reference to the InterfaceRepository or CORBA::Object::_nil()

static maci::Manager_ptr maci::MACIHelper::resolveManager (CORBA::ORB_ptr orb, const ACE_TCHAR * reference, int retries = 3, unsigned int secTimeout = 0) [static] resolveManager method resolve given stringified CORBA reference to the Maneger.

Parameters:

orb CORBA ORB
reference stringified CORBA reference to the Manager
retries number of retries resolving Manager reference, <= 0 means infinite
secTimeout timeout expressed in seconds, == 0 means inifinite (dt between retries is 3secs)

Returns:

CORBA reference to the Manager or maci::Manager::_nil() if unable to resolve Manager reference

static maci::Manager_ptr maci::MACIHelper::resolveManager (CORBA::ORB_ptr orb, int argc, ACE_TCHAR ** argv, int retries = 3, unsigned int secTimeout = 0) [static] resolveManager method is a method helping to resolve Manager’s reference. The Manager reference is defined by the first valid of the following options: # Command line option -m or -managerReference # ManagerReference value in configuration database # Environment variable MANAGER_REFERENCE # corbaloc::<hostname>:xxxx/Manager

Parameters:

orb CORBA ORB
argv command line parameter count
argc command line array of strings
retries number of retries resolving Manager’s reference, <= 0 means infinite
secTimeout timeout expressed in seconds, == 0 means inifinite (dt between retries is 3 secs)

Returns:

CORBA reference to the Manager or maci::Manager::_nil() if unable to resolve Manager’s reference

static CosNaming::NamingContext_ptr maci::MACIHelper::resolveNameService (CORBA::ORB_ptr orb, const ACE_TCHAR * reference, int retries = 3, unsigned int secTimeout = 0) [static] resolveNameService method resolve given stringified CORBA reference to the NameService.

Parameters:

orb CORBA ORB
reference stringified CORBA reference to the NameService
retries number of retries resolving NameService reference, <= 0 means infinite
secTimeout timeout expressed in seconds, == 0 means inifinite (dt between retries is 3secs)

Returns:

CORBA reference to the NameService’s root CosNaming::NamingContext or CosNaming::NamingContext::_nil() if unable to resolve NameService reference

static CosNaming::NamingContext_ptr maci::MACIHelper::resolveNameService (CORBA::ORB_ptr orb, int retries = 3, unsigned int secTimeout = 0) [static] resolveNameService method is a method helping to resolve CORBA NameService’s reference. The NameService reference is defined by the first valid of the following options: # Command line option -ORBInitRef NameService=<corbaloc reference>=’’> (e.g. corbaloc::te1.hq.eso.org:xxxx) using CORBA::ORB::resolve_initial_references(’NameService’), ORB has to be already initialized with the command line # Environment variable NAMESERVICE_REFERENCE # corbaloc::<hostname>:xxxx/NameService

Parameters:

orb CORBA ORB
retries number of retries resolving NameService reference, <= 0 means infinite
secTimeout timeout expressed in seconds, == 0 means inifinite (dt between retries is 3secs)

Returns:

CORBA reference to the NameService’s root CosNaming::NamingContext

static void maci::MACIHelper::terminateResolving (bool terminate = true) [static] Terminates all resolving processes

Parameters:

terminate true is all resolving processes are to be cancelled (default), false to set termiante flag to false

bool maci::MACIHelper::m_terminate [static, private]
