public final class ASTWildcardType extends AbstractJjtreeNode<net.sourceforge.pmd.lang.java.ast.AbstractJavaNode,JavaNode> implements ASTReferenceType
Represents a wildcard type. Those can only occur when nested in an ASTTypeArguments node. 

 WildcardType ::= "?" ( ("extends" | "super") ReferenceType )?

  • Field Details

  • Method Details

    • isUpperBound

      public boolean isUpperBound()
      Return true if this is an upper type bound, e.g. <? extends Integer>, or the unbounded wildcard <?>.

    • isLowerBound

      public boolean isLowerBound()
      Returns true if this is a lower type bound, e.g. in <? super Node>.

    • getTypeBoundNode

      public @Nullable ASTReferenceType getTypeBoundNode()
      Returns the type node representing the bound, e.g. the Node in <? super Node>, or null in the unbounded wildcard <?>.

    • acceptVisitor

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

    • 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.
