public final class ASTUnionType extends AbstractJjtreeNode<net.sourceforge.pmd.lang.java.ast.AbstractJavaNode,JavaNode> implements ASTReferenceType, Iterable<ASTClassType>
Represents the type node of a multi-catch statement. This node is used to make the grammar of CatchParameter more straightforward. Note though, that the Java type system does not feature union types at all. The type of this node is defined as the least upper-bound of all its components. 

 UnionType ::= ClassType ("|" ClassType)+

      Returns a stream of component types.

    • getFirstChild

      default ASTClassType getFirstChild()
      Returns the first child of this node, never null.
      Specified by:

      Specified by:
      getFirstChild in interface Node

    • getLastChild

      default ASTClassType getLastChild()
      Returns the last child of this node, never null.

    • getTypeMirror

      public @NonNull JTypeMirror getTypeMirror()
      Description copied from interface: TypeNode
      Returns the compile-time type of this node. For example, for a string literal, returns the type mirror for String, for a method call, returns the return type of the call, etc.

      This method ignores conversions applied to the value of the node because of its context. For example, in 1 + "", the numeric literal will have type int, but it is converted to String by the surrounding concatenation expression. Similarly, in Collections.singletonList(1), the ASTNumericLiteral node has type int, but the type of the method formal is Integer, and boxing is applied at runtime. Possibly, an API will be added to expose this information.

      Specified by:
      getTypeMirror in interface TypeNode
      Returns:
      The type mirror. Never returns null; if the type is unresolved, returns TypeSystem.UNKNOWN.
