\page KERNEL_Services KERNEL Services for end user (Python interface)
In a %SALOME application, distributed components, servers and clients use
the CORBA middleware for comunication. CORBA interfaces are defined via idl
files. All the different CORBA interfaces are available for users in Python,
see CORBA interfaces below.
For some general purpose services, CORBA interfaces have been encapsulated
in order to provide a simple interface (encapsulation is generally done in
C++ classes, and a Python SWIG interface is also generated from C++, to
ensure a consistent behavior between C++ modules and Python modules or user
script).
\section S1_kernel_ser General purpose services
\subsection subsection11 SALOME services access from a Python shell
See \ref SALOME_Application for detailed instructions on how to launch a Python
interpreter with full access to the %SALOME environment and services.
You can use the embedded Python interpreter in Graphical User Interface, or an
external interpreter, with:
\code
./runSession
python
\endcode
In either cases, %SALOME services access is done with:
\code
import salome
salome.salome_init()
\endcode
In the embedded interpreter, it is already done, but there is no problem to
do it several times, so it is preferable to add these instructions
systematically in your scripts, to allow them to work in all configurations.
See \ref kernel_salome for a short description of most useful variables and
functions.
\subsection subsection12 Container and component instanciation
See SALOME_LifeCycleCORBA for the C++ interface (Python interface obtained with SWIG
is very similar).
In the following example, a test component provided in KERNEL is launched
in the local container, "FactoryServer", created when %SALOME starts:
\code
import salome
salome.salome_init()
import LifeCycleCORBA
lcc = LifeCycleCORBA.LifeCycleCORBA()
obj=lcc.FindOrLoad_Component("FactoryServer","SalomeTestComponent")
import Engines
comp=obj._narrow(Engines.TestComponent)
comp.Coucou(1)
\endcode
The answer is something like:
\code
'TestComponent_i : L = 1'
\endcode
The _narrow() instruction is not always mandatory in Python, but sometimes
useful to be sure you have got the right type of %object. Here, Testcomponent
interface is defined in CORBA module Engines. With this example, it works also
without the _narrow() instruction:
\code
obj.Coucou(1)
\endcode
In the next example, a component instance is created in a specific Container
defined by it's computer hostname and it's name. Here we use the local
computer. Note that in Utils_Identity, Utils_Identity::getShortHostName() gives the short
hostname of the computer, without domain suffixes, which is used in %SALOME.
The container process is created here if it does not exists, and a new
component instance is created:
\code
import salome
salome.salome_init()
import LifeCycleCORBA
lcc = LifeCycleCORBA.LifeCycleCORBA()
import Utils_Identity
host = Utils_Identity.getShortHostName()
import Engines
params={}
params['hostname']=host
params['container_name']='myContainer'
comp=lcc.LoadComponent(params,'SalomeTestComponent')
comp.Coucou(1)
\endcode
If you want to get a list of containers and component instances, client %object
from orbmodule provides a list:
\code
import orbmodule
clt=orbmodule.client()
clt.showNS()
\endcode
The list looks like:
\code
Logger.
ContainerManager.object
Containers.dir
cli70ac.dir
FactoryServerPy.object
SuperVisionContainer.object
FactoryServer.object
FactoryServer.dir
SalomeTestComponent_inst_1.object
myContainer.object
myContainer.dir
SalomeTestComponent_inst_1.object
SalomeTestComponent_inst_2.object
Registry.object
Kernel.dir
ModulCatalog.object
Session.object
Study.dir
Study2.object
extStudy_1.object
extStudy_2.object
extStudy_3.object
myStudyManager.object
SalomeAppEngine.object
\endcode
\subsection subsection13 File transfer service
See SALOME_FileTransferCORBA for the C++ interface (Python interface obtained with
SWIG is very similar).
The following example shows how to tranfer a file from a remote host to the
client computer. Remote hostname is 'cli76cc', we would like to copy
'tkcvs_8_0_3.tar.gz' from remote to local computer. %A full pathname is
required. %A container is created on remote computer if it does not exist,
to handle the file transfer:
\code
import salome
salome.salome_init()
import LifeCycleCORBA
remotefile="/home/prascle/tkcvs_8_0_3.tar.gz"
aFileTransfer=LifeCycleCORBA.SALOME_FileTransferCORBA('cli76cc',remotefile)
localFile=aFileTransfer.getLocalFile()
\endcode
\subsection subsection14 CORBA Naming service access
See SALOME_NamingService for the C++ interface. The Python interface
SALOME_NamingServicePy::SALOME_NamingServicePy_i is not yet derived from the C++ interface and offers
only the most useful functions.
\subsection subsection5 Batch services
See Batch documentation (in french only).
