| [ROOT] Writing TClonesArray to File Oliver Oberst 16:23:24 |
| | Hello,
I am writing a rootinterface for a MC Generator. I wrote my on
eventclass, verticesclass and particleclass all inheriting from TObject.
Now in the interface i make a tree and give a Branch the events address.
in This eventbrach i want to have a TClonesArray of my vertexobjects.
I built the dictionary and it worked so that the event and the vertex
class have their own streamer.
I tested the TClonesarray in the code so that i now know that filling
the TClonesArray workes(I can readout vertex members after filling the
array).
I think the problem is when the event streamer calls the
'TClonesArrayobject'->Streamer(b) and there the Vertex Streamer is not
called. Because i only see the events members as leafes and one leaf
with the name of the TClonesArray. Normaly it should be browsable
because i split the tree (with 99). I now do not see why the
TClonesArray with my Vertex Objects are not streamed in the file and it
is not browsable...
Code:
-------------------------------------------------------------------
Streamers in dictionary which is linked in my shared lib:
void HepMCEvent::Streamer(TBuffer &R__b)
{
// Stream an object of class HepMCEvent.
UInt_t R__s, R__c;
if (R__b.IsReading()) {
Version_t R__v = R__b.ReadVersion(&R__s, &R__c); if (R__v) { }
TObject::Streamer(R__b);
R__b >> signal_process_id;
R__b >> event_number;
R__b >> event_scale;
R__b >> alphaQCD;
R__b >> alphaQED;
R__b >> vertices_size;
Vertices->Streamer(R__b);
R__b.CheckByteCount(R__s, R__c, HepMCEvent::IsA());
} else {
R__c = R__b.WriteVersion(HepMCEvent::IsA(), kTRUE);
TObject::Streamer(R__b);
R__b << signal_process_id;
R__b << event_number;
R__b << event_scale;
R__b << alphaQCD;
R__b << alphaQED;
R__b << vertices_size;
Vertices->Streamer(R__b);
R__b.SetByteCount(R__c, kTRUE);
}
}

void HepMCVertex::Streamer(TBuffer &R__b)
{
// Stream an object of class HepMCVertex.
UInt_t R__s, R__c;
if (R__b.IsReading()) {
Version_t R__v = R__b.ReadVersion(&R__s, &R__c); if (R__v) { }
TObject::Streamer(R__b);
R__b >> barcode;
R__b >> id;
R__b >> position_x;
R__b >> position_y;
R__b >> position_z;
R__b >> position_t;
R__b >> numOrphan;
R__b >> particles_out_size;
R__b.CheckByteCount(R__s, R__c, HepMCVertex::IsA());
} else {
R__c = R__b.WriteVersion(HepMCVertex::IsA(), kTRUE);

| [ROOT] (Pi/2. ) != (90.0 DegToRad) Kathrin Stoerig 11:25:04 |
| | Hello,
I have been working with some trigonometric functions of the
"TMath"-Class when I discovered a peculiar behaviour of ROOT v5.0.12e.
I have appended a stand-alone piece of my code. The comments at the end
show my output when compiling or interpreting.
While interpreting with Cint, everything is okay, but when I compile it,
the following comparison is astonishing to me:
"Double_t phi=90.0*TMath::DegToRad();
if (phi==TMath::Pi()/2.0) returns "false",
while if(phi==TMath::PiOver2()) returns true?! "
Much more interesting is the fact, that:
"Double_t phi=90.0*TMath::DegToRad();
cout<<phi<<endl;
if (phi==TMath::Pi()/2.0) now returns "true" - instead of "cout" e.g.
an empty "for"-loop is possible and still returns "true", a variable
declaration as "Int_t a=5" returns "false" and "Double_t
b=TMath::Cos(5.)" returns "true" again.
Any ideas?
As you can see in my code, I tried a lot of possibilities (casting the
numbers to doubles, updating ROOT to version 5.0.14 etc.) without
success. Please tell me whats wrong or how to prevent this infelicitous
situation.

| [ROOT] X11 and Threads... Daniel Cussol 11:14:08 |
| | Hello everybody,
I am trying to build a multi-thread application in which I need to
refresh canvases. Unfortunately, this leads usually to a complete
freezing of my application. It seems as it is mentioned in the
documentation that there still are some problems with W11 and threads. I
have nevertheless noticed that when I select the "interrupt" item in the
"Option" menu of the TCanvas before refreshing it, all seemed to be Ok.
My question is then: what sequence of commans and/or code is activated
when one select the "interrupt" item in the "Option" menu of the
TCanvas? I was not clever enough to obtain this information from the
source code.
I run ROOT v5.12.00 on MacOs X.3.9 and on SL4.
Thanks for your help.

| Cross Platform Key mapper. Joseph A. Marrero 07:07:20 |
| | Hi guys. I am trying to implement a class that maps either
X11 and/or Microsoft Windows physical keys to logical keys.
The purpose is hide the implementation details regarding
keyboard keys in a portable manner and be able to use
logical keys within my application without needing an
implementation defined.
This is easy to do on MS Windows because all of the virtual
keys (VK_) map cleanly onto an array of integers of size
255. On X11, I run into a problem. Some of the XK_ key
symbols are larger than 254 and seem to throw my design out
of the window.
So, I store the mapping into an array:
LogicalKey m_KeyMappingTable[ MAX_NUMBER_OF_KEYS ];
And I translate physical keys to logical keys with the
following:
LogicalKey COSKeyMapper::translateKey( unsigned int
physicalKey )
{
return m_KeyMappingTable[ physicalKey ];
}
So to build this translation table I just initialize the
m_KeyMappingTable array. The LogicalKey data type is an
enumeration of all possible logical keys. I hope I
explained this well.
This scheme doesn't seem to work well in X11 because for
example, XK_Escape is 0xff1b (to large for an index into my
array). I don't want to use a std::map because I want to
have translateKey() run in constant time. I would greatly
appreciate any advice and tips on what I am trying to do
and whether it is the norm when people want to write
portable keyboard code. Thank you in advance.
