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<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
refport's Corba reference.
provides_port_nameport's name.
port_propport'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_idport's Corba repository id. Eg : IDL:toto.tata/MODULE/INTERFACE_NAME:1.0
uses_port_nameport's name.
port_propport'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_nameservice's name.
Exceptions
containsinformations 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_nameservice's name.
Exceptions
containsinformations about files that are not in a good state.

in Ports::Port  provides_port_ref 
) raises (PortNotDefined, BadPortType, NilPort)
inherited

Parameters
port_nameport's name.
Returns
properties object's CORBA reference.
Exceptions
PortNotDefined
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_nameport's name.
connection_errortrue 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_nameport's name.
Returns
uses port's sequence.
Exceptions
PortNotDefined
PortNotConnected
BadPortType

Get version of the component.

This method is supposed to be implemented in all derived classes; default implementation returns "unknown" string that means that no version information about the component is available.
