  32  * The interfaces in this package do not model the structure of a
  33  * program inside a method body; for example there is no
  34  * representation of a {@code for} loop or {@code try}-{@code finally}
  35  * block.  However, the interfaces can model some structures only
  36  * appearing inside method bodies, such as local variables and
  37  * anonymous classes.
  38  *
  39  * <p>When used in the context of annotation processing, an accurate
  40  * model of the element being represented must be returned.  As this
  41  * is a language model, the source code provides the fiducial
  42  * (reference) representation of the construct in question rather than
  43  * a representation in an executable output like a class file.
  44  * Executable output may serve as the basis for creating a modeling
  45  * element.  However, the process of translating source code to
  46  * executable output may not permit recovering some aspects of the
  47  * source code representation.  For example, annotations with
  48  * {@linkplain java.lang.annotation.RetentionPolicy#SOURCE source}
  49  * {@linkplain java.lang.annotation.Retention retention} cannot be
  50  * recovered from class files and class files might not be able to
  51  * provide source position information.  The {@linkplain
  52  * javax.lang.model.element.Modifier modifiers} on an element may
  53  * differ in some cases including

  59  * </ul>
  60  *
  61  * Additionally, synthetic constructs in a class file, such as
  62  * accessor methods used in implementing nested classes and bridge
  63  * methods used in implementing covariant returns, are translation
  64  * artifacts outside of this model.
  65  *
  66  * <p>During annotation processing, operating on incomplete or
  67  * erroneous programs is necessary; however, there are fewer
  68  * guarantees about the nature of the resulting model.  If the source
  69  * code is not syntactically well-formed or has some other
