[omniORB] Passing a Sequence from Python to C++

[Ridgway, Richard (London)]

Sequences are mapped to python lists or tuples.
1.3.2 of the omg python languange mapping has this:

The sequence template is mapped to sequence objects (e.g., tuples or
lists).
Applications should not assume that values of a sequence type are
mutable. Sequences
and arrays of octets and characters are mapped to the string type for
efficiency reasons.
For example, given the IDL definitions
typedef sequence<long> LongList;
interface VectorOps{
long sum(in LongList l);
};
a client could invoke the operation
print obj.sum([1,2,3])



Thus in your case
sequence_of_params = [param1,param2]

Subject: [omniORB] Passing a Sequence from Python to C++



Hello,

I'm new to CORBA and Python and want to pass a sequence from Python to
C++.

My IDL-file:

interface idlfile
	{
		
		struct param
		{
			string value1;
	   		             any value2;

		};

                typedef sequence param dict;

The generated code:
Struct:
class param:
def __init__(self, value1, value2)

Sequence:
class dict:
def __init__(self, *args, **kw)

I want to initialize the params in this way:
pm1 = idlfile.param("example1","example2")
But I don't know how to initialize the sequence?

How do I initialize a sequence of params und how do I pass them to C++?

Is it possible to put the sequence into a dictionary and to pass this to
C++?

I'm looking forward for your replies.

Greetings,
EntonH
