Interface of a DSC component.
This interface defines the operations needed to add a component model with dynamic port declaration to the SALOME object model. A component is a black box that interacts with other components only by his ports. A port represents a connection point for the component. In this model, a port is a CORBA interface, so a CORBA object.
There is two ways for a component to interact with a port type :
The interface DSC implements the component interface that containes the operations that are needed to manage declarations into a component and connections between ports.
These operations are logicaly divided in two parts :
typedef sequence<Ports::Port> Engines::DSC::uses_port |
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.
void Engines::DSC::add_provides_port | ( | in Ports::Port | ref, |
in string | provides_port_name, | ||
in Ports::PortProperties | port_prop | ||
) | raises (PortAlreadyDefined, NilPort, BadProperty) |
This operation adds a provides port to the component.

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.
service_name | service's name. |
contains | informations about files that are not in a good state. |
|
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.
service_name | service's name. |
contains | informations about files that are not in a good state. |
void Engines::DSC::connect_provides_port | ( | in string | provides_port_name | ) | raises (PortNotDefined) |

Get a python dump.
Returns a python script, which is being played back reproduces the data model of component
Ports::PortProperties Engines::DSC::get_port_properties | ( | in string | port_name | ) | raises (PortNotDefined) |
Get port's property object.
port_name | port's name. |
PortNotDefined |
Ports::Port Engines::DSC::get_provides_port | ( | in string | provides_port_name, |
in boolean | connection_error | ||
) | raises (PortNotDefined, PortNotConnected, BadPortType) |
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.
provides_port_name | port's name. |
connection_error | true if you want to wait that the port is connected with an another port. |
PortNotDefined | |
PortNotConnected | |
BadPortType |
uses_port Engines::DSC::get_uses_port | ( | in string | uses_port_name | ) | raises (PortNotDefined, PortNotConnected, BadPortType) |
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).
uses_port_name | port's name. |
PortNotDefined | |
PortNotConnected | |
