Examples of javax.lang.model.util.Types.asElement()

javax.lang.model.util.Types.asElement()
Returns the element corresponding to a type. The type may be a {@code DeclaredType} or {@code TypeVariable}. Returns {@code null} if the type is not one with acorresponding element. @param t the type to map to an element @return the element corresponding to the given type
