      public Variant(String name, CustomHashSet<ASTNode> astNodesMainTree, AbstractAST productAST, CustomHashSet<Feature> features)
      Constructs a new Variant object with the given parameters.
      Parameters:
      name - the name of the variant
      astNodesMainTree - the main tree of AST nodes of the variant
      productAST - the abstract syntax tree of the variant
      features - the set of features associated with the variant

      public Variant(Variant other)
      Creates a new Variant object by copying the contents of another Variant object.
      Parameters:
      other - The Variant object to copy from
      Throws:
      UnsupportedOperationException - if the productAST type is not JavaAST or LineAST

      public org.logicng.formulas.Formula getMappingFromPosition(Position position)
      Returns the mapping of the node at the given position in the variant's AST or, if it has already been merged into the main tree, the mapping of the corresponding node in the main tree.
      Parameters:
      position - The position of the node to find the mapping for
      Returns:
      The mapping of the node at the given position, or null if no node is found

      Parameters:
      position - The position to search for in the variant's AST.
      Returns:
      The ASTNode at the given position in the variant's AST, or the corresponding node in the main tree if merged.
