Examples of javax.lang.model.element.TypeElement

javax.lang.model.element.TypeElement
Represents a class or interface program element. Provides access to information about the type and its members. Note that an enum type is a kind of class and an annotation type is a kind of interface.
While a {@code TypeElement} represents a class or interfaceelement, a {@link DeclaredType} represents a classor interface type, the latter being a use (or invocation) of the former. The distinction is most apparent with generic types, for which a single element can define a whole family of types. For example, the element {@code java.util.Set} corresponds to the parameterized types{@code java.util.Set} and {@code java.util.Set}(and many others), and to the raw type {@code java.util.Set}.
Each method of this interface that returns a list of elements will return them in the order that is natural for the underlying source of program information. For example, if the underlying source of information is Java source code, then the elements will be returned in source code order. @author Joseph D.
