| /** |
| * Represents a class in the AST. |
| * <p> |
| * A ClassNode should be created using the methods in ClassHelper. |
| * This ClassNode may be used to represent a class declaration or |
| * any other type. This class uses a proxy mechanism allowing to |
| * create a class for a plain name at AST creation time. In another |
| * phase of the compiler the real ClassNode for the plain name may be |
| * found. To avoid the need of exchanging this ClassNode with an |
| * instance of the correct ClassNode the correct ClassNode is set as |
| * redirect. Most method calls are then redirected to that ClassNode. |
| * <p> |
| * There are three types of ClassNodes: |
| * <ol> |
| * <li> Primary ClassNodes:<br> |
| * A primary ClassNode is one where we have a source representation |
| * which is to be compiled by Groovy and which we have an AST for. |
| * The groovy compiler will output one class for each such ClassNode |
| * that passes through AsmBytecodeGenerator... not more, not less. |
| * That means for example Closures become such ClassNodes too at |
| * some point. |
| * <li> ClassNodes create through different sources (typically created |
| * from a java.lang.reflect.Class object):<br> |
| * The compiler will not output classes from these, the methods |
| * usually do not contain bodies. These kind of ClassNodes will be |
| * used in different checks, but not checks that work on the method |
| * bodies. For example if such a ClassNode is a super class to a primary |
| * ClassNode, then the abstract method test and others will be done |
| * with data based on these. Theoretically it is also possible to mix both |
| * (1 and 2) kind of classes in a hierarchy, but this probably works only |
| * in the newest Groovy versions. Such ClassNodes normally have to |
| * isResolved() returning true without having a redirect.In the Groovy |
| * compiler the only version of this, that exists, is a ClassNode created |
| * through a Class instance |
| * <li> Labels:<br> |
| * ClassNodes created through ClassHelper.makeWithoutCaching. They |
| * are place holders, its redirect points to the real structure, which can |
| * be a label too, but following all redirects it should end with a ClassNode |
| * from one of the other two categories. If ResolveVisitor finds such a |
| * node, it tries to set the redirects. Any such label created after |
| * ResolveVisitor has done its work needs to have a redirect pointing to |
| * case 1 or 2. If not the compiler may react strange... this can be considered |
| * as a kind of dangling pointer. |
| * </ol> |
| * <b>Note:</b> the redirect mechanism is only allowed for classes |
| * that are not primary ClassNodes. Typically this is done for classes |
| * created by name only. The redirect itself can be any type of ClassNode. |
| * <p> |
| * To describe generic type signature see {@link #getGenericsTypes()} and |
| * {@link #setGenericsTypes(GenericsType[])}. These methods are not proxied, |
| * they describe the type signature used at the point of declaration or the |
| * type signatures provided by the class. If the type signatures provided |
| * by the class are needed, then a call to {@link #redirect()} will help. |
