All Implemented Interfaces:

Serializable, Comparable<IBond.Stereo>

Enclosing interface:

IBond
```
public static enum IBond.Stereo
extends Enum<IBond.Stereo>
```
Enumeration of possible stereo types of two-atom bonds. The Stereo type defines not just define the stereochemistry, but also the which atom is the stereo center for which the Stereo is defined. The first atom in the IBond (index = 0) is the start atom, while the second atom (index = 1) is the end atom.

Enum Constant Summary

Enum Constants
Enum Constant and Description
`DOWN` A bond pointing down of which the start atom is the stereocenter and the end atom is below the drawing plane.
`DOWN_INVERTED` A bond pointing down of which the end atom is the stereocenter and the start atom is below the drawing plane.
`E` Indication that this double bond has a E configuration.
`E_OR_Z` Indication that this double bond has a fixed, but unknown E/Z configuration.
`E_Z_BY_COORDINATES` Indication that this double bond has a fixed configuration, defined by the 2D and/or 3D coordinates.
`NONE` A bond for which there is no stereochemistry.
`UP` A bond pointing up of which the start atom is the stereocenter and the end atom is above the drawing plane.
`UP_INVERTED` A bond pointing up of which the end atom is the stereocenter and the start atom is above the drawing plane.
`UP_OR_DOWN` A bond for which there is stereochemistry, we just do not know if it is UP or DOWN.
`UP_OR_DOWN_INVERTED` A bond for which there is stereochemistry, we just do not know if it is UP or DOWN.
`Z` Indication that this double bond has a Z configuration.

- Method Detail
  - values
```
public static IBond.Stereo[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (IBond.Stereo c : IBond.Stereo.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static IBond.Stereo valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
