How to know what default things are?

Pompei2

Hello,

Is it somehow possible to see, during runtime, what the "default" stuff (for example: protocol and host) of a communicator are?

I searched a lot and the most obvious way:

communicator()->getProperties()->getProperty("Ice.Default.Protocol");

does not work, too bad!

I noticed that all properties are gone from the communicator. Listing the whole property set gives me just the following:

Ice.Config=
  Ice.ProgramName=./client

That is not much information at all!

I feel I could create a dummy proxy then convert it to a string and parse that string, but this is a gigantic hack and requires the proxy to connect successfully!

Is there really no way?

PS: My application inherits from Ice::Application

You can call getPropertiesForPrefix with an empty string as the argument and then iterate over the returned dictionary to see all the properties.

Cheers,

Michi.

Michi, it still looks like there are some values with the logic:

  if ""==properties.getProperty("Ice.Default.Protocol",""):
     useDefault()

rather than having those defaults assigned to the properties instance on initialization:

$ python

>>> import Ice 
ic = I>>> ic = Ice.initialize()
>>> m = ic.getProperties().getPropertiesForPrefix("")
>>> m
{'Ice.Default.CollocationOptimized': '0', 'Ice.Config': ''}
>>>

By doing this, I noticed that nearly all properties of the communicator are gone after the initialization (I'm sure they are set before!). That's what I meant by this:

within the run() method of my overwritten service class, all the properties I give to main() (by command line or programmatically) are gone.

Properties do not get cleared after communicator initialization. Perhaps you should post the (small/complete/compilable) code you are using to test this so we can take a closer look.

Things are getting clearer. While building a minimalistic example to demonstrate my problem, the problem has gone away. I'll look more into this later, now I have to go learn

Hello,

just to inform you that (as suspected in my last post) the problem was, of course, on my side. I wasn't giving the correct argument vector to the main method of the ice application object. Thanks for the help.
