Examples of com.google.dart.engine.ast.CompilationUnit

com.google.dart.engine.ast.CompilationUnit
Instances of the class {@code CompilationUnit} represent a compilation unit.
While the grammar restricts the order of the directives and declarations within a compilation unit, this class does not enforce those restrictions. In particular, the children of a compilation unit will be visited in lexical order even if lexical order does not conform to the restrictions of the grammar.
```
 compilationUnit ::= directives declarations directives ::= {@link ScriptTag scriptTag}?  {@link LibraryDirective libraryDirective}? namespaceDirective*  {@link PartDirective partDirective}|  {@link PartOfDirective partOfDirective}namespaceDirective ::= {@link ImportDirective importDirective}|  {@link ExportDirective exportDirective}declarations ::= {@link CompilationUnitMember compilationUnitMember}
```
