Math::Expr::Opp - Represents one operation in the parsed expression tree River stage zero No dependents

Used by the Math::Expr to represent algebraic expressions. This class represents one operation or function with a set of operands, which in turn can be other Math::Expr::Opp objects. And in that way we are able to represent entire expression. Operati...
