Only the first element of array of properties is read from cpf file. How to have all the elemets of the array read?

Submitted by gprizzi on Tue, 2011-05-10 17:28

Dear Sirs,

I am working on Orocos toolchain 2.3.2 and I am developing a test components using orogen.

I have problem in reading array of properties from cpf file

I prepared a cpf file using the following lines of code:

obstaclesPositions obs=obstaclesPositions(1.0,2.0,3.0);
obstacleP op(4.0,5.0,6.0);
obs.obsPosition.push_back(op);
_Obstacles.set(obs);
boost::shared_ptr<Marshalling> Marshalling = this->getProvider<RTT::Marshalling>("marshalling");
result = Marshalling->writeProperties("ObstaclesDescription.cpf");

and I get the following ObstaclesDescription.cpf file

<?xml version="1.0" encoding="UTF-8"?>
&lt;!DOCTYPE properties SYSTEM "cpf.dtd"&gt;
<properties>
<struct name="Obstacles" type="/viewer/obstaclesPositions">
<description>actual number and position of obstacles in the work area<description>
<struct name="obsPosition" type="/std/vector&lt;/viewer/obstacleP&gt;">
<description>Part<description>
<struct name="Element0" type="/viewer/obstacleP">
<description>Item<description>
<simple name="lenght_x" type="double"><description>Part<description><value>1<value><simple>
<simple name="lenght_y" type="double"><description>Part<description><value>2<value><simple>
<simple name="lenght_z" type="double"><description>Part<description><value>3<value><simple>
<struct>
<struct name="Element1" type="/viewer/obstacleP">
<description>Item<description>
<simple name="lenght_x" type="double"><description>Part<description><value>4<value><simple>
<simple name="lenght_y" type="double"><description>Part<description><value>5<value><simple>
<simple name="lenght_z" type="double"><description>Part<description><value>6<value><simple>
<struct>
<struct>
<struct>
<properties>

containing a property of type obstaclesPositions with two elements of type obstacleP.

I write a test component that have to read this file and store the read values in a variable of type
obstaclesPositions.

I tried the following code inserted in configureHook:

boost::shared_ptr<Marshalling> Marshalling = this->getProvider<RTT::Marshalling>("marshalling");
result = Marshalling->readProperties("ObstaclesDescription.cpf");
obstaclesPositions obs;
obs = _Obstacles.get();

But only the Element0 of the array is read.

I tried also the following code:

MarshallingService m=MarshallingService(this);
result=m.readProperty("Obstacles","ObstaclesDescription.cpf");

But even in this case only Element0 is read.

How can I do to have all the elements read and assigned to the properties _Obstacles?

_Obstacles is a property defined in the following orogen code:

name 'viewer3d'
version '1.0'
import_types_from "viewer3d.h"

task_context "Viewer3d" do
needs_configuration
property("Obstacles","viewer/obstaclesPositions").
doc('sizes of obstacles in the work area')
end

And in the file viewer3d.h I defined the following types:

class obstacleP
{
public:
double lenght_x;
double lenght_y;
double lenght_z;

obstacleP()
{

lenght_x=0.0;
lenght_y=0.0;
lenght_z=0.0;
}
};

class obstaclesPositions
{
public:
std::vector<obstacleP> obsPosition;

obstaclesPositions()
{

obstacleP oP;

oP.lenght_x=0.0;
oP.lenght_y=0.0;
oP.lenght_z=0.0;

obsPosition.push_back(oP);
}
};

Thank you for your support.

I have pushed and tested a fix on toolchain-2.3. You need to recompile RTT and
your application. Thanks for the example code and the report.

I can confirm this report. This is the output of the -ldebug flag: (see comments...)

Up until here, the property was written out and contained a sequence of two elements. Next, we clear the property's vector, and we
re-read the same file:

0.048 [ Info ][PropertyLoader:configure] Configuring TaskContext 'viewer3d' with 'ObstaclesDescription.cpf'.
0.054 [ Debug ][PropertyLoader:configure] Returning part: obsPosition

0.054 [ Debug ][PropertyLoader:configure] Returning part: size
0.055 [ Debug ][PropertyLoader:configure] Returning part: size

What happens here is that a default obsPosition is created, even though the one of our property is empty. It is
decomposed...

0.055 [ Debug ][refreshProperties] refreshing Property PropertyBag obsPosition from PropertyBag obsPosition
0.055 [ Debug ][refreshProperties] refreshing Property PropertyBag Element0 from PropertyBag Element0
0.055 [ Debug ][refreshProperties] refreshing Property double lenght_x from double lenght_x
0.055 [ Debug ][refreshProperties] refreshing Property double lenght_y from double lenght_y
0.055 [ Debug ][refreshProperties] refreshing Property double lenght_z from double lenght_z

'refreshing' means that no expansion is done of the vector. So the default one is refreshed with the results of the file...

0.055 [ Debug ][PropertyLoader:configure] Used user's composition function for Obstacles:/viewer/obstaclesPositions

Next we write out the result: only one element in the property:

The fishy part is that refreshproperties does not make sense for sequences (ie vector<T>). I'm working on a fix.
