Examples of org.eclipse.jdt.core.dom.PackageDeclaration

org.eclipse.jdt.core.dom.PackageDeclaration
Package declaration AST node type. For JLS2:
```
 PackageDeclaration: package Name ; 
```
For JLS3, annotations and doc comment were added:
```
 PackageDeclaration: [ Javadoc ] { Annotation } package Name ; 
```
Note that the standard AST parser only recognizes a Javadoc comment immediately preceding the package declaration when it occurs in the special package-info.java compilation unit (JLS3 7.4.1.1). The Javadoc comment in that file contains the package description. @since 2.0 @noinstantiate This class is not intended to be instantiated by clients.
