Class UnionType

java.lang.Object

com.github.javaparser.ast.Node

com.github.javaparser.ast.type.Type

com.github.javaparser.ast.type.UnionType

All Implemented Interfaces:

NodeWithAnnotations<UnionType>, NodeWithRange<Node>, NodeWithTokenRange<Node>, Observable, Visitable, HasParentNode<Node>, Resolvable<ResolvedType>, Cloneable

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.

 try {
 ...
 } catch(IOException | NullPointerException ex) {
 ...
 }
 

The types that make up the union type are its "elements"
