-_HowTo Add a New Tag to GDML_ - -Following the strategies in Radovan Chytracek's C++ -implementation of the GDML processor, here are the -steps to add a generic tag "t" to a GDML schema and -process it in your application. - -# add t and attrib/child elements to the extended schema document and test/validate - -# add t to gdml "test file" and test/validate - -# required (or at least highly recommended) C++ classes for t will usually include... - # tType - # type from the schema - # maybe it has no parent class if the type doesn't - # get/set for common attributes - # get/set_content methods if it has children (see, for instance, VolumeType.h) - # t - # element of type tType - # inherits from tType and SAXObject - # may or may not implement get/set methods, depending on if these were put in the tType interface - # tProcess - # data interface to subscribers - # inherits from SAXStateProcess or tTypeProcess (if exists) - # tSubscriber - # subscriber to create application objects from SAXObject - # inherits from SAXSubscriber - -# create tProcess - - # StartElement - # new t - # m_obj = t - # topObject = *Context()->GetTopObject() = t - # parent::EndElement(..) [if exists] - # parent element *should not* set m_obj/topObject, only common attribute settings! - - # StackPopNotify [if applicable] - # add children using set_content - - # DECLARE_PROCESS_FACTORY(tProcess) - - # State() - # return "t" as str - -# add LOAD_COMPONENT(tProcess) to UserLoad() - -# create tSubscriber - - # Activate() - - # dynamic cast SAXObject to t - - # if cast = ok, create application object tObj from t's process data - # use tProcess->set_() methods - # do expression evaluation using GDMLExpressionEvaluator - # lookup referenced elements using ref->get_ref() - # add to GDML object stores in GDMLProcessor [optional] - - # iterate over children using ContentSequence and fill tObj [if - applicable] (see VolumeSubscriber, for instance) - - # DECLARE_SUBSCRIBER_FACTORY(tSubscriber) - -# add LOAD_COMPONENT(tSubscriber) to UserLoad() - -# make sure UserLoad() is called at initialization time - -_Caveats and Problems_ - -# If you add a process to a certain tag, the default GDML process is overridden. - Thus, your process must implement (somehow) all of the behavior of the - process it is replacing, including attribute setup and adding children. - This can be done through (careful) use of inheritance. - -# The default Activate() methods in subscribers delete the received SAXObject; - thus, if you subscribe to GDML objects (not your own), the SAXObject received - will be invalid! (i.e. already deleted) The only "solution" I have found is to - count on the fact that your subscriber will be called after GDML's. Thus the - call to delete can be removed from GDML's subscriber and your's should - include it. This isn't much of a proper solution, and I am waiting on input - from Radovan on this. - -# If you add a tag that is a child of an existing GDML tag, it may not - be available in the parent tag's SAXObject. This is because the - StackPopNotify() function of the child tag's process may check for specific, - known child tags. The workaround is to make the GDML process push your child - (or all children) into its content. The main example of this is - SinglePlacementTypeProcess, which looks for two known GDML tags and ignores - others, probably your added tag, in my case physvolid. - -# Minor build system complaints... - - # gmake doesn't work if arch isn't exact match. Fake with gmake "SCRAM_ARCH=...". - # Geant4 examples hardcode global libs, which may not be built.

--geant4/Subscribers/volumeSubscriber.cpp - -removed delete (happens in $LCDD_BASE/src/volumeExtendedSubscriber.cc) - --Processes/Processes/SinglePlacementTypeProcess.h - -"physvolid" to content in StackPopNotify()

-<h2>Summary of Changes Since Last Release</h2>
-
-<ul>
-<li>Bug fixed in combining tracker hits with G4TrackerCombineSD.  Energy cut is now performed on the final combined hit rather than individual steps.
-<li>Bug fixed in RZBFieldMap where steps at the boundary caused the algorithm to crash.  Action at boundary is now much simpler and doesn't crash.
-<li>Verbose output from sensitive detectors was improved, especially for G4TrackerCombineSD.
-<li>CalorimeterHits can now be aggregated using position or ID of the virtual readout cell.
-<li>A command was added to dump GDML from the command line or macro interface.
-<li>Global field overlay was added and is the default behavior of the field manager.
-<li>Two commands for checking overlaps using the built-in functions of G4LogicalVolume were added to the /lcdd command dir.
-<li>A simple dipole magnet type was added to the LCDD format.
-<li>Interactive commands to loaded sensitive detectors was added in the /detectors macro directory.
-<li>The verbosity of sensitive detectors can be modified at runtime using the /detectors commands.
-</ul>
