enum Chem::BondOrder

Overview

A BondOrder provides a type-safe representation of the bond order of a covalent between two atoms.

Zero = 0: Zero bond order, e.g., Schrodinger represents bonds between metals as zero-order bonds. May also indicate unknown or unspecified order.
Single = 1: Single bond order
Double = 2: Double bond order
Triple = 3: Triple bond order

#==(rhs : Int) : Bool
Returns true if the integer representation of the bond order is equal to rhs, else false.
#double?
Returns true if this enum value equals Double
#pred : self
Decreases the bond order.
#single?
Returns true if this enum value equals Single
#succ : self
Increases the bond order.
#to_char : Char
Returns the char representation of the bond order.
#triple?
Returns true if this enum value equals Triple
#zero?
Returns true if this enum value equals Zero

def ==(rhs : Int) : Bool #

Returns true if the integer representation of the bond order is equal to rhs, else false.
