"nb-javac" is a patched version of OpenJDK "javac", i.e., the Java compiler. This has long been part of NetBeans, providing a highly tuned Java compiler specifically for the Java editor i.e., parsing and lexing for features such as syntax coloring, code completion.

* The nesting kind of a type element.
* Type elements come in four varieties:
* top-level, member, local, and anonymous.
* Nesting kind is a non-standard term used here to denote this
* classification.
*
* Note that it is possible additional nesting kinds will be added
* in future versions of the platform.
*
*
Example: The classes below are annotated with their nesting kind.
*
*
* import java.lang.annotation.*;
* import static java.lang.annotation.RetentionPolicy.*;
* import javax.lang.model.element.*;
* import static javax.lang.model.element.NestingKind.*;

* @Nesting(TOP_LEVEL)
* public class NestingExamples {
* @Nesting(MEMBER)
* static class MemberClass1{}
*
* @Nesting(MEMBER)
* class MemberClass2{}
*
* public static void main(String... argv) {
* @Nesting(LOCAL)
* class LocalClass{};
*
* Class<?>[] classes = {
* NestingExamples.class,
* MemberClass1.class,
* MemberClass2.class,
* LocalClass.class
* };
*
* for(Class<?> clazz : classes) {
* System.out.format("%s is %s%n",
* clazz.getName(),
* clazz.getAnnotation(Nesting.class).value());
* }
