TypeElement

public interface TypeElement implements Element
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 interface element, a {@link DeclaredType} represents a class or 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.

Fields Summary
Constructors Summary
Methods Summary
public java.util.ListgetInterfaces()
Returns the interface types directly implemented by this class or extended by this interface.

return
the interface types directly implemented by this class or extended by this interface, or an empty list if there are none

public javax.lang.model.element.NestingKindgetNestingKind()
Returns the nesting kind of this type element.

return
the nesting kind of this type element

public javax.lang.model.element.NamegetQualifiedName()
Returns the fully qualified name of this type element. More precisely, it returns the canonical name. For local and anonymous classes, which do not have canonical names, an empty name is returned.

The name of a generic type does not include any reference to its formal type parameters. For example, the fully qualified name of the interface {@code java.util.Set} is "{@code java.util.Set}". Nested types use "{@code .}" as a separator, as in "{@code java.util.Map.Entry}".

return
the fully qualified name of this class or interface, or an empty name if none

public javax.lang.model.type.TypeMirrorgetSuperclass()
Returns the direct superclass of this type element. If this type element represents an interface or the class {@code java.lang.Object}, then a {@link NoType} with kind {@link TypeKind#NONE NONE} is returned.

return
the direct superclass, or a {@code NoType} if there is none

public java.util.ListgetTypeParameters()
Returns the formal type parameters of this type element in declaration order.

return
the formal type parameters, or an empty list if there are none
