Detailed Description

Implementation for ASCII output of objects with ROOT dictionary.

The method JRootWriter::put is compatible with equation formatting, i.e:

<key>[<division><key>]<separator><value>[<white space><value>]*<end of line>

In this, the key corresponds to the name of a data member which can be recursively parsed via a division character.

The method JRootWriter::putObject relates to simple formatting, i.e:

<value>[<white space><value>]*

The default format for output of std::vector<T> is

<number of elements>[<white space><value>]*
