public final class UnionType extends Type implements NodeWithAnnotations<UnionType>
The union type
Represents a set of types. A given value of this type has to be assignable to at least one of the element types.Java 1-6
Does not exist.Java 7+
As of Java 7 it is used in catch clauses.
The types that make up the union type are its "elements"try { ... } catch(IOException | NullPointerException ex) { ... }
