Detailed Description

Interface of the MPI parallel container. This interface defines the process of loading and registration of new components in SALOME application.

Member Function Documentation

boolean Engines::Container::load_component_Library	(	in string	componentName,
		out string	reason
	)

inherited

Loads a new component class (dynamic library).

Parameters

componentName	like COMPONENT, (Python or C++ implementation) try to make a Python import of COMPONENT, then a lib open of libCOMPONENTEngine.so
reason	in case of error (return false) a string explaining the error

Returns: true if load successfull or already done, false otherwise

Engines::EngineComponent Engines::Container::create_component_instance	(	in string	componentName,
		in long	studyId
	)

inherited

Create a new servant instance of a component.

Component library must be loaded.

Parameters

componentName	Name of the component which will be registered in Registry and Name Service, (instance number suffix added to the registered name)
studyId	0 if instance is not associated to a study, >0 otherwise (== study id)

Returns: a loaded component

string Engines::Container::create_python_service_instance	(	in string	serviceName,
		out string	reason
	)

inherited

Create a new Python servant instance of a generic service.

This simply loads the service in the current container by importing the corresponding Python module. Warning: no internal registration is done, so it is up to the caller to manage the various instanciation.

Parameters

serviceName	Name of the service >0 otherwise (== study id)
reason	in case of error (return void string) a string explaining the error

Returns: the IOR of the loaded service.

Engines::EngineComponent Engines::Container::create_component_instance_env	(	in string	componentName,
		in long	studyId,
		in FieldsDict	env,
		out string	reason
	)

inherited

Create a new servant instance of a component with environment variables specified.

Component library must be loaded.

Parameters

componentName	Name of the component which will be registered in Registry and Name Service, (instance number suffix added to the registered name)
studyId	0 if instance is not associated to a study, >0 otherwise (== study id)
env	a dict of env variables
reason	in case of error (return nil) a string explaining the error

Returns: a loaded component

EngineComponent Engines::Container::find_component_instance	(	in string	registeredName,
		in long	studyId
	)

inherited

Find a servant instance of a component.

Parameters

registeredName	Name of the component in Registry or Name Service, without instance suffix number
studyId	0 if instance is not associated to a study, >0 otherwise (== study id)

Returns: the first instance found with same studyId

EngineComponent Engines::Container::load_impl	(	in string	nameToRegister,
		in string	componentName
	)

inherited

Find a servant instance of a component, or create a new one.

Loads the component library if needed. Only applicable to multiStudy components.

Parameters

nameToRegister	Name of the component which will be registered in Registry (or Name Service)
componentName	Name of the constructed library of the component (not used any more, give empty string)

Returns: a loaded component

void Engines::Container::remove_impl ( in EngineComponent component_i )

inherited

Remove the component servant, and deletes all related objects.

Parameters

component_i Component to be removed

void Engines::Container::finalize_removal ( )

inherited

Unload component libraries from the container.

void Engines::Container::ping ( )

inherited

Determines whether the server has been loaded or not.

void Engines::Container::Shutdown ( )

inherited

Shutdown the Container process.

string Engines::Container::getHostName ( )

inherited

Returns the hostname of the container.

long Engines::Container::getPID ( )

inherited

Returns the PID of the container.

boolean Engines::Container::Kill_impl ( )

inherited

Kill the container.

Returns True if the container has been killed. Kept for Superv compilation but can't work, unless oneway... TO REMOVE !

fileRef Engines::Container::createFileRef ( in string origFileName )

inherited

Create a fileRef.

returns a fileRef object if origFileName exists and is readable else returns null object. Only one fileRef is created for a given file name, so, several calls with the same file name returns the same object.

Salome_file Engines::Container::createSalome_file ( in string origFileName )

inherited

Create a Salome_file.

returns a Salome_file object if origFileName exists and is readable else returns null object.

Parameters

origFileName name of the file to be managed (can contain the path).

Returns: Salome_file CORBA reference.

fileTransfer Engines::Container::getFileTransfer ( )

inherited

Create a fileTransfer.

returns a fileTransfer object used to copy files from the container machine to the clients machines. Only one fileTransfer instance is created in a container.

void Engines::Container::copyFile	(	in Container	contai,
		in string	remoteFile,
		in string	localFile
	)

inherited

Copy a file from a remote host (container) to a local file.

Parameters

contai	the remote container
remoteFile	the file on the remote host to copy
localFile	the local file to create by copy

PyNode Engines::Container::createPyNode	(	in string	nodeName,
		in string	code
	)		raises (SALOME::SALOME_Exception)

inherited

Create a PyNode in the container.

Parameters

nodeName	the name of the PyNode
code	python code as text to load in the node

PyNode Engines::Container::getDefaultPyNode ( in string nodeName )

inherited

Retrieves the last created PyNode instance with createPyNode.

PyScriptNode Engines::Container::createPyScriptNode	(	in string	nodeName,
		in string	code
	)		raises (SALOME::SALOME_Exception)

inherited

Create a PyScriptNode in the container.

Parameters

nodeName	the name of the PyScriptNode
code	python code as text to load in the node

PyScriptNode Engines::Container::getDefaultPyScriptNode ( in string nodeName )

inherited

Retrieves the last created PyScriptNode instance with createPyScriptNode.
