\doxysubsection{Detailed Description}
Abstract base class for chemical composition representations. 

The purpose of this class is to define a standard interface for all composition types. Children of this class are responsible for implementing the setter methods, but any object that is a child of \doxylink{classfourdst_1_1composition_1_1_composition_abstract}{Composition\+Abstract} will always have these getter methods.

This ensures that all derived composition classes provide a consistent API for querying composition properties, regardless of how the data is set or stored.
