Re: [ptp-dev] Accessing parallel launch resource attributes
|
Hi Wyatt,
The attributes are roughly divided into RM-specific and non RM-
specific. The latter are defined in
org.eclipse.ptp.core.IPTPLaunchConfigurationConstants and these
correspond to the Application, Arguments, Synchronize, and Debugger
tabs. The former are defined in the RM plugin and correspond to the
Resources tab. I say "roughly" because there may be some non RM-
specific attributes that are no longer used, but haven't been cleaned
out yet.
Unfortunately, number of processes falls into the RM-specific
attributes, since not all systems may require this. I'm not quite sure
about the best way to deal with it though. One way would be to provide
a global number of processes attribute that all RM's use, and which
defaults to 1 in the case of RM's that don't need it. But this doesn't
address the issue of other RM-specific attributes that you might need
access to (are there any?) A more generic solution would be to query
the RM for the attributes, but this would still require some knowledge
of the attributes you were expecting. The debugger actually queries
the internal model to find out the number of processes for a job, but
this only provides the information after the job has started, so is no
use if you need it before then.
I don't know what the best solution is. Suggestions appreciated.

Greetings,
I need to retrieve and alter parallel launch parameters
programatically to support some of the external tools framework's
capabilities. I have access to the LaunchConfiguration and the
ILaunch object provided by the PTP's launch configuration delegate
but I am having trouble tracking down the configuration attribute
names for things like the number of processes to be run. I haven't
dug deep enough to be sure but it looks like there are now different
attribute names for these parameters depending on which resource
manager is used. Does anyone know how I can recover these values
from within Eclipse?
Thanks,
Wyatt Spear
