HLT::TriggerElement::FeatureAccessHelper Class Reference

the FeatureAccessHelper is a class used to keep track of features attached to this TE. The storage is organized somewhere outside the TriggerElement (i.e. Navigation) Once the TE is queried for the features it returns this access helpers and the entity is supposed to make reasonable use of it. There is number of advantages.

1. TriggerElement objects are lighter
2. the external storage can be organized more efficient
3. query for all features of given type can be much quicker
4. TriggerElement object can be streamed as it is (the index, CLID) remain valid after deserialization
5. the features can be serialized separately facilitating requirement of safe truncation
