Detailed Description

template<class JKey_t>
class JSUPPORT::JAutoTreeWriter< JKey_t >

Auxiliary class to copy input data to corresponding TTree.

This class derives from JROOT::JRootOutputFile. It re-implements the methods open and close of the underlying JLANG::JAccessible class so that each TTree is properly attached to and detached from the corresponding TDirectory, respectively.
