Detailed Description

template<class T>
class SG::ToTransient< T >

Define a hook for running code after an object has been read.

Some objects need additional processing after reading in order to be usable. (ROOT read rules are often not ideal since there is no way to pass them an EventContext other than via the global thread-local lookup.) ToTransient<U>::toTransient will be called for the container of an xAOD auxiliary variable after it has been read (for an auxiliary variable of type T, this will usually be std::vector<T>). It will also be called from ATLAS POOL converters after an object has been read.

If noToTransient is defined, then the converters may skip actually making the toTransient calls for this type.
