japa.parser.ast.CompilationUnit

This class represents the entire compilation unit. Each java file denotes a compilation unit.
The CompilationUnit is constructed following the syntax:
CompilationUnit ::= ( {@link PackageDeclaration} )? ( {@link ImportDeclaration} )* ( {@link TypeDeclaration} )* @author Julio Vilmar Gesser


    public final String getCompilationUnitContents(
            final ClassOrInterfaceTypeDetails cid) {
        Validate.notNull(cid, "Class or interface type details are required");
        // Create a compilation unit to store the type to be created
        final CompilationUnit compilationUnit = new CompilationUnit();


        // NB: this import list is replaced at the end of this method by a
        // sorted version
        compilationUnit.setImports(new ArrayList<ImportDeclaration>());


        if (!cid.getName().isDefaultPackage()) {
            compilationUnit.setPackage(new PackageDeclaration(ASTHelper
                    .createNameExpr(cid.getName().getPackage()
                            .getFullyQualifiedPackageName())));
        }


        // Add the class of interface declaration to the compilation unit
        final List<TypeDeclaration> types = new ArrayList<TypeDeclaration>();
        compilationUnit.setTypes(types);
