Examples of TypeMirror

Represents a generic type. @author Stéphane Épardaud
com.sun.mirror.type.TypeMirror
Represents a type in the Java programming language. Types include primitive types, class and interface types, array types, and type variables. Wildcard type arguments, and the pseudo-type representing the type of void, are represented by type mirrors as well.
Types may be compared using the utility methods in {@link Types}. There is no guarantee that any particular type will always be represented by the same object. @author Joseph D. Darcy @author Scott Seligman @version 1.4 05/11/17 @see Declaration @see Types @since 1.5
javax.lang.model.type.TypeMirror
Represents a type in the Java programming language. Types include primitive types, declared types (class and interface types), array types, type variables, and the null type. Also represented are wildcard type arguments, the signature and return types of executables, and pseudo-types corresponding to packages and to the keyword {@code void}.
Types should be compared using the utility methods in {@link Types}. There is no guarantee that any particular type will always be represented by the same object.
To implement operations based on the class of an {@code TypeMirror} object, either use a {@linkplain TypeVisitor visitor}or use the result of the {@link #getKind} method. Using {@code instanceof} is not necessarily a reliable idiom fordetermining the effective class of an object in this modeling hierarchy since an implementation may choose to have a single object implement multiple {@code TypeMirror} subinterfaces. @author Joseph D.
