public final class ASTIntersectionType
extends AbstractJjtreeNode<net.sourceforge.pmd.lang.java.ast.AbstractJavaNode,JavaNode>
implements ASTReferenceType, Iterable<ASTType>

Represents an intersection type. Can only occur in the following contexts:

• As the bound of a TypeParameter
• As the target type of a CastExpression, on Java 8 and above

The first type can be a class or interface type, while the additional bounds are necessarily interface types.

 IntersectionType ::= ClassOrInterfaceType ("&" InterfaceType)+

Method Detail

getComponents

public NodeStream<ASTClassType> getComponents()

Returns a stream of component types.

acceptVisitor

protected <P,R> R acceptVisitor(JavaVisitor<? super P,? extends R> visitor,
                                      P data)

iterator

public Iterator<ASTType> iterator()

Specified by:

iterator in interface Iterable<ASTType>

getFirstChild

public default @NonNull T getFirstChild()

Returns the first child of this node, never null.

Specified by:

getFirstChild in interface GenericNode<T extends JavaNode>

Specified by:

getFirstChild in interface Node

getLastChild

public default @NonNull T getLastChild()

Returns the last child of this node, never null.

Specified by:

getLastChild in interface GenericNode<T extends JavaNode>

Specified by:

getLastChild in interface Node

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.
