Detailed Description

template<typename T>
class o2::framework::InputRecord::Deleter< T >

A deleter type to be used with unique_ptr, which can be marked that it does not own the underlying resource and thus should not delete it. The resource ownership property controls the behavior and can only be set at construction of the deleter in the unique_ptr. Falls back to default_delete if not initialized to 'NotOwning'. Usage: unique_ptr<T, Deleter<T>> ptr(..., Deleter<T>(false))

By contract, the underlying, not owned resource is supposed to be available during the lifetime of the object, which is the case in the InputRecord and DPL processing APIs. The Deleter can be extended to support a callback to call a resource management outside.
