Detailed Description

template<typename KeyType>
struct o2::framework::GenericRootTreeReader< KeyType >::SpecialPublishHook

A struct holding a callback to specialize publishing based on branch name. This might be useful when the read data needs to be transformed before publishing. The hook gets the following input: name: name of branch (may be used for selecting filtering) context: The processing context (so that we can snapshot or publish) Output: The DPL output channel on which to publish data: pointer to the data object read by the TreeReader The hook should return true when publishing succeeded and false when the ordinary publishing procedure should proceed.
