TutorialAddingConnectionToXML

@@ +1 @@
+= Adding connection to the XML file =
+
+Let us suppose that we have createad a component ```MyComponent``` as described in [[TutorialAddingComponentToXML|previous tutorial]].
+
+
+Also, we suppose that we had added an input called "pose-low-quality" and an output called "pose-high-quality" to our class ```MyComponent```.
+
+**Inputs:** We will take our input from a component of class ```LowCostGps``` named ```gps``` which has an output called ```"pose"```.
+
+**Outputs:** We will send our processed pose to another component ```othercomp``` of class ```OtherComponent`` which has an input called ```"pose"```.
+
+**Warning:**
+Output ```"pose"``` in class ```LowCostGps``` has the same type as our input ```"pose-low-quality"```.
+Similarly, input ```"pose"``` in class ```OtherComponent``` has the same type as our output ```"pose-high-quality"```.
+
+To add a connection, we will modify the ```connections``` node of the XML file.
+The rest of the file rests unchanged.
