\begin{Indent}{\bf Constructors}\par
{\em Construction of each \hyperlink{classbdm_1_1epdf}{epdf} should support two types of constructors: \begin{itemize}
\item empty constructor, \item copy constructor,\end{itemize}
The following constructors should be supported for convenience: \begin{itemize}
\item constructor followed by calling {\tt set\_\-parameters()} \item constructor accepting random variables calling {\tt \hyperlink{classbdm_1_1epdf_f423e28448dbb69ef4905295ec8de8ff}{set\_\-rv()}} \end{itemize}
All internal data structures are constructed as empty. Their values (including sizes) will be set by method {\tt set\_\-parameters()}. This way references can be initialized in constructors. }\begin{CompactItemize}
