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:
  `java.lang.IllegalArgumentException` - if this enum type has no constant with the specified name
  `java.lang.NullPointerException` - if the argument is null

#### toString

    public java.lang.String toString()

Deprecated.

Overrides:
  `toString` in class `java.lang.Enum<Relationship>`

#### oppositeRelationship

    public Relationship oppositeRelationship()

Deprecated.
