Detailed Description

template<typename KeyType>
class o2::framework::GenericRootTreeReader< KeyType >::BranchConfigurationInterface

The interface for the branch configuration. The branch configuration is constructed at compile time from the constructor argments of the tree reader. A mixin class is constructed from nested instances of

Run the reader process This will recursively run every level of the the branch configuration and fetch the object at position entry. The object is published via the DPL ProcessingContext. A creator callback for the header stack is provided to build the stack from the variadic list of header template arguments.
