  TypeMirror asType()

  Returns the type defined by this class or interface element, returning the Italics style removed.!diff-dfn! added.Moved to a span with id prototypicaltype and class search-tag-result.prototypical !diff-dfn! added.Moved to a span with id prototypicaltype and class search-tag-result.type !diff-dfn! added.Moved to a span with id prototypicaltype and class search-tag-result. for an element representing a generic type.

  A generic element defines a family of types, not just one. If this is a generic element, a prototypical type is returned which has the element's invocation on the type variables corresponding to its own formal type parameters. For example, for the generic class element C<N extends Number> , the parameterized type C<N> is returned. Otherwise, for a non-generic class or interface, the prototypical type mirror corresponds to a use of the type. None of the components of the prototypical type are annotated, including the prototypical type itself.

  public abstract java.util.List<? extends javax.lang.model.element.Element> getEnclosedElements()

  Comparing jdk-21-ga and jdk-22+36

  getEnclosedElements

  List<? extends Element> getEnclosedElements()

  Returns the fields, methods, constructors, record components, and member classes and interfaces that are directly declared in this class or interface. This includes any mandated elements such as the (implicit) default constructor and the implicit values and valueOf methods of an enum class.

  Specified by:

  getEnclosedElements  in interface Element

  API Note:

  As a particular instance of the general accuracy requirements and the ordering behavior required of this interface, the list of enclosed elements will be returned in the natural order for the originating source of information about the class or interface. For example, if the information about the class or interface is originating from a source file, the elements will be returned in source code order. (However, in that case the ordering of implicitly declared elements, such as default constructors, is not specified.)

  Returns:

  the enclosed elements in proper order, or an empty list if none

  Returns the permitted classes of this class or interface element in declaration order. Note that for an interface, permitted subclasses and subinterfaces can be returned.

  Implementation Requirements:

  The default implementations of this method returns an empty and unmodifiable list.

  Returns:

  the permitted classes, or an empty list if there are none

  getQualifiedName

  Name getQualifiedName()

  Returns the fully qualified name of this class or interface element. More precisely, it returns the canonical name. For local, and anonymous , and unnamed^PREVIEW classes, which do not have canonical names, an empty name is returned.

  The name of a generic class or interface does not include any reference to its formal type parameters. For example, the fully qualified name of the interface java.util.Set<E> is "java.util.Set ". Nested classes and interfaces use ". " as a separator, as in "java.util.Map.Entry ".
