Detailed Description

Interface of the Superv_Component.

This interface is a DSC component that contains services for the SALOME module SUPERV. This interface contains methods that are only in local (so they are described and explained in the implementation class Superv_Component_i). These methods give access to data-oriented ports provided by default by SALOME's kernel.

Member Typedef Documentation

typedef sequence<multiple_param> Engines::Superv_Component::seq_multiple_param

typedef sequence<Ports::Port> Engines::DSC::uses_port

inherited

a uses port

This sequence is a uses port. It's a sequence since a uses port can be connected with x provides port. Sometimes this kind of uses port is called multiple port. At this programming level, the user has to deal with the sequence. In the DSC_user layer, the user only deals with one pointer.

Member Enumeration Documentation

enum Engines::DSC::Message

inherited

This enumeration is used when the connection of a port (uses or provides) is changed.

This information is for the component's user code.

void Engines::DSC::add_provides_port	(	in Ports::Port	ref,
		in string	provides_port_name,
		in Ports::PortProperties	port_prop
	)		raises (PortAlreadyDefined, NilPort, BadProperty)

inherited

This operation adds a provides port to the component.

Parameters

ref	port's Corba reference.
provides_port_name	port's name.
port_prop	port's property object.

Exceptions

PortAlreadyDefined
NilPort
BadProperty

Note: Notice that the name of the port is unique on a component. So if there is a uses port that has the same name, the PortAlreadyDefined exception will be throw. Also notice that each port as an object property that is associated with.

void Engines::DSC::add_uses_port	(	in string	repository_id,
		in string	uses_port_name,
		in Ports::PortProperties	port_prop
	)		raises (PortAlreadyDefined, BadProperty)

inherited

This operation adds a uses port to the component.

Parameters

repository_id	port's Corba repository id. Eg : IDL:toto.tata/MODULE/INTERFACE_NAME:1.0
uses_port_name	port's name.
port_prop	port's property object.

Exceptions

Note: Notice that the name of the port is unique on the component. So if there is a provides port that has the same name, the PortAlreadyDefined exception will be throw. Also notice that each port as an object property that is associated with.

void Engines::EngineComponent::checkInputFilesToService ( in string service_name ) raises (SALOME::SALOME_Exception)

inherited

Check service input files (transfer them if needed)

This method is used before the activation of the service. It calls recvFiles() on all the input Salome_file files of the service.

Before each recvFiles(), it uses the callback method named configureSalome_file. This method allows the user to configure the files managed by the Salome_file.

By default, there is no files managed when a Salome_file is created, but the supervisor set some files managed by the Salome_file from the information contained into the schema file.

Parameters

service_name service's name.

Exceptions

contains informations about files that are not in a good state.

void Engines::EngineComponent::checkOutputFilesToService ( in string service_name ) raises (SALOME::SALOME_Exception)

inherited

Check service output files (transfer them if needed)

This method is used at the end of the service. It calls recvFiles() on all the output Salome_file files of the service.

Before each recvFiles(), it uses the callback method named configureSalome_file. This method allows the user to configure the files managed by the Salome_file.

By default, there is no files managed when a Salome_file is created, but the supervisor set some files managed by the Salome_file from the information contained into the schema file.

Parameters

service_name service's name.

Exceptions

contains informations about files that are not in a good state.

Ports::Port Engines::DSC::get_provides_port	(	in string	provides_port_name,
		in boolean	connection_error
	)		raises (PortNotDefined, PortNotConnected, BadPortType)

inherited

Get a provides port of the component.

It can be used by the framework or the component himself.

If it's the framework that wants the port, the reference has to be gived even if the port is not connected (boolean connection_error to false). Contrary, if it's the component that wants the port, the port is given in most of cases only if it is connected (boolean connection_error to true). Notice that you can choose the behaviour that you want.

Parameters

provides_port_name	port's name.
connection_error	true if you want to wait that the port is connected with an another port.

Returns: port's Corba reference.

Exceptions

PortNotDefined
PortNotConnected
BadPortType

uses_port Engines::DSC::get_uses_port ( in string uses_port_name ) raises (PortNotDefined, PortNotConnected, BadPortType)

inherited

Get a uses port of the component.

It can be used by the framework or the component himself. Actually, only the user layer of the component will use this operation. A uses port could be obtained if and only if the uses port is connected. The sequence contains all the connections since a uses port can have multiple connections.

There is a system of callbacks to prevent the user code that there is a new (or a deletion) of a connection (see DSC_Callbacks class).

Parameters

uses_port_name port's name.

Returns: uses port's sequence.

Exceptions

PortNotDefined
PortNotConnected
BadPortType
