TrigObjectNavMatching works for "simple trigger chains" [simp trig chains]. Matches, based on trigger navigation, trigger objects [HltDoc] for each trigger level to trigger objects from previous levels and to chains.  Creates as output [NavMatchedObjectChain] for all objects passing the trigger for a given slice.  
Requires as input strings listing chain names for slice and the three slice specific labels of the trigger objects for the three trigger levels - EF,L2, and L1.  Exception tau... slice can be selected by... see [Input/ Output]

Also can match the [NavMatchedObjectChains] to offline objects using the TrigObjectMatching[] tool. This requires the label of the offline objects to match.  

"Simple Trigger Chains"[simp trig chains]
   * Involve only one ROI   
   * Can be backtraced unambiguously 
      * Ex: treeish diagram
   * Contain only one final trigger object per trigger level 
      * the trigger object must inherit from INav4momentum
      * There may be multiple trigger objects in a given trigger level; however at the end of the chain there should be only one object that unambigously defines the INav4Momentum.
   * Ex: composite triggers such as 2 tau are not supported

See also the [hltDoc] for description of terms in this document.

tool test:<br />
get chains using chain group for all single tau chains TDT getChainGroup(std::vector<std::string> triggers)<br />
get vector of chain names strings for all single tau chains from chain group [[https://twiki.cern.ch/twiki/bin/view/Atlas/TrigDecisionTool15][TDT]]  function of chaingroup object: getListOfTriggers() returns vector string of chain names<br />
print the chain names to test tool<br />



<br /><br />
per event

loop over chain name strings<br />
then use m_trigDecisionTool->features(chainName, condition); condition is TrigDefs::alsoDeactivateTEs to return feature container<br />

loop over three trigtypes... for each trigtype<br />
   use featurecontainer->get<trigType>("", TrigDefs::alsoDeactivateTEs); to return vector of features<br />
   test if vector of features has length greater than 0<br />
   assemble trigger element, trig object/feature? and chain name into hubobject<br />
   push hubobject onto vector of hub objects for given trigger level(trig type)<br />
 end loops over trigtypes - chain names<br />

have 3 vectors 1 for each level of hubobjects<br />
form linkage objects from hublight objects...<br />
use ancestor function of te's to find relations..  <br />

object names:
   * FeatureChainLnkBase for feature, te and trig obj, with addition label of chain string
   * TrigNavObj for trigger object extracted from feature with chain label and ROI word attached - without te 
   * TrigNavLinkage for the three(possibly more) objects of the Trig Nav matching tool linked by ancestry
   * TrigNavLinkage can also contain pointer to offline object that linkage head is matched to

*05.08.09*

object names:
   * FeatureChainLnkBase for feature, te and trig obj, with addition label of chain string
   * TrigNavObj for trigger object extracted from feature with chain label and ROI word attached - without te 
   * TONLinkage for the three(possibly more) objects of the Trig Nav matching tool linked by ancestry
   * TONLinkage has also pointer to vector of offline objects that linkage head is matched to - non null if matching done
   * TONBranch linkages that share common ancestor 

created using templating with 3 templates for trigtype classes 1 additional template for offline matching if done if not done can leave as generic dataobj

What is result of passing INav4Momentum as feature?

*26.08.09*

matching objects to objects through levels
   * store gate retrieve for each - vector of object* of type T
   * TrigEvent/TrigNavigation/..Navigation.h 
      * template<class T> bool findOwners(const T* obj, std::vector<const TriggerElement*>& owners, unsigned int id = 0);
      * returns vector of HLT::TrigElement* 's (Nav Trig elements)
   * Get? chain name from Nav Trig Element?
   * link to preceeding trig object from trig obj's already retrieved
      * find te* t1, te* t2 is t1 seeded by t2?

For all instances of object related to physical cause does object have same pointer?
