Detailed Description

template<typename T>
class edm::DeviceProduct< T >

A wrapper for Event Data product in device memory accompanied with some device-specific metadata. Not intended to be used directly by developers (except in ROOT dictionary declarations in classes_def.xml similar to edm::Wrapper).

Get the actual data product after the metadata object has synchronized the access. The synchronization details depend on the metadata type, which the caller must know. All the arguments are passed to M::synchronize() function.
