[cdt-dev] C++ Indexer not getting updated on programmatic additions to a

[Pavan V Ananth <pavan.ananth@xxxxxxxxxx>]

I can see that a update to the C++ indexer
gets automatically triggered when any change is done to a C++ file and
saved. I don't see this behavior when a org.eclipse.ltk.core.refactoring.CompositeChange
object is used to create file changes on the C++ file and then a perform()
call is fired on the change. 

Specifically speaking, if I want to
insert a new field to the C++ class programmatically using the CompositeChange
object, I construct a change object with the InsertEdit changes and fire
a perform call on the change.
I can see a delta fired for the new
field addition by the CModelManager with the delta looking like -

 CMODEL [*]: {CHILDREN | FINE
GRAINED}
        IndexerTest
CPROJECT [*]: {CHILDREN | FINE GRAINED}
         
      IndexerTest SOURCE_ROOT [*]: {CHILDREN | FINE
GRAINED}
         
              C1.h TRANSLATION_UNIT
[*]: {CHILDREN | FINE GRAINED}
         
               
      C1 C_CLASS [*]: {CHILDREN}
         
               
              ival C_FIELD
[+]: {}

I can also see that the new field is
inserted into the file successfully and a build automatically triggered
on the project. But strangely, this does not trigger an update on the index.


Isn't this a defect?
