| - * elsewhere in the code.
|
| - *
|
| - * There are two exceptions to the general case. First, there are elements in
|
| - * the element model that are created for the convenience of various kinds of
|
| - * analysis but that do not have any corresponding declaration within the source
|
| - * code. Such elements are marked as being <i>synthetic</i>. Examples of
|
| - * synthetic elements include
|
| - * * default constructors in classes that do not define any explicit
|
| - * constructors,
|
| - * * getters and setters that are induced by explicit field declarations,
|
| - * * fields that are induced by explicit declarations of getters and setters,
|
| - * and
|
| - * * functions representing the initialization expression for a variable.
|
| - *
|
| - * Second, there are elements in the element model that do not have a name.
|
| - * These correspond to unnamed functions and exist in order to more accurately
|
| - * represent the semantic structure of the program.

| -/**
|
| - * An element visitor that will recursively visit all of the elements in an
|
| - * element model (like instances of the class [RecursiveElementVisitor]). In
|
| - * addition, when an element of a specific type is visited not only will the
|
| - * visit method for that specific type of element be invoked, but additional
|
| - * methods for the supertypes of that element will also be invoked. For example,
|
| - * using an instance of this class to visit a [MethodElement] will cause the
|
| - * method [visitMethodElement] to be invoked but will also cause the methods
|
| - * [visitExecutableElement] and [visitElement] to be subsequently invoked. This
|
| - * allows visitors to be written that visit all executable elements without
|
| - * needing to override the visit method for each of the specific subclasses of
|
| - * [ExecutableElement].
|
| - *
|
| - * Note, however, that unlike many visitors, element visitors visit objects
|
| - * based on the interfaces implemented by those elements. Because interfaces
|
| - * form a graph structure rather than a tree structure the way classes do, and
|
| - * because it is generally undesirable for an object to be visited more than
|
| - * once, this class flattens the interface graph into a pseudo-tree. In
|
| - * particular, this class treats elements as if the element types were
|
| - * structured in the following way:
|
| - *
|
| - * <pre>
|
| - * Element
|
| - * ClassElement
|
| - * CompilationUnitElement
|
| - * ExecutableElement
|
| - * ConstructorElement
|
| - * LocalElement
|
| - * FunctionElement
|
| - * MethodElement
|
| - * PropertyAccessorElement
|
| - * ExportElement
|
| - * HtmlElement
|
| - * ImportElement
|
| - * LabelElement
|
| - * LibraryElement
|
| - * MultiplyDefinedElement
|
| - * PrefixElement
|
| - * TypeAliasElement
|
| - * TypeParameterElement
|
| - * UndefinedElement
|
| - * VariableElement
|
| - * PropertyInducingElement
|
| - * FieldElement
|
| - * TopLevelVariableElement
|
| - * LocalElement
|
| - * LocalVariableElement
|
| - * ParameterElement
|
| - * FieldFormalParameterElement
|
| - * </pre>
|
| - *
|
| - * Subclasses that override a visit method must either invoke the overridden
|
| - * visit method or explicitly invoke the more general visit method. Failure to
|
| - * do so will cause the visit methods for superclasses of the element to not be
|
| - * invoked and will cause the children of the visited node to not be visited.
