Note that the structure may have member functions, typically class-specific operator new and operator delete These member functions allow use of the ORB on platforms that have non-uniform memory management However, any additional member functions in the structure are purely internal to the mapping; you should ignore them and write your code as if they did not exist The _var_type definition is used for templatebased programming, and we show an example of its use in Section 18141 You can use the generated structure just as you use any other C++ structure in your code For example:

C++ permits static initialization of aggregates A class, structure, or array is an aggregate if it does not have user-declared constructors, base classes, virtual functions, or private or protected non-static data members The preceding structure is an aggregate, so you can initialize it statically:

Details d = { 85, 12 };
Bar Code Generation In Visual Basic .NET
Using Barcode encoder for Visual Studio .NET Control to generate, create bar code image in Visual Studio .NET applications.
Some C++ compilers have problems with aggregate initializations, so use the feature with caution 6132 Mapping for Variable-Length Structures The Details structure shown in the preceding section is a fixed-length type, so there are no memory management issues to consider For variable-length structures, the C++ mapping must deal with memory management Here is an example:
Drawing Code 3 Of 9 In .NET Framework
Using Barcode drawer for ASP.NET Control to generate, create Code 3/9 image in ASP.NET applications.
struct Fraction { double numeric; string alphabetic; };
Barcode Generation In Java
Using Barcode creation for Java Control to generate, create barcode image in Java applications.
This structure is a variable-length type because one of its members is a string Here is the corresponding C++ mapping:
Data Matrix 2d Barcode Creation In Visual C#
Using Barcode creator for VS .NET Control to generate, create Data Matrix 2d barcode image in .NET applications.
class Fraction_var; struct Fraction { CORBA::Double numeric; CORBA::String_mgr alphabetic; typedef Fraction_var _var_type; // Member functions here };
Create Bar Code In .NET
Using Barcode encoder for .NET framework Control to generate, create barcode image in VS .NET applications.
As before, you can pretend that any member functions in the structure do not exist As you can see, the IDL string is mapped to a type String_mgr instead of String_var or char * String_mgr behaves like a String_var except that the default constructor initializes the string to the empty string instead of initializing it to a null pointer In general, strings nested inside user-defined types (such as structures, sequences, exceptions, and arrays) are always initialized to the empty string instead of to a null pointer Initializing to the empty string for nested types is useful because it means that you need not explicitly initialize all string members inside a user-defined type before

sending it across an IDL interface (As you will see in Section 71415, it is illegal to pass a null pointer across an IDL interface)[2]
Making GS1 - 12 In Visual Studio .NET
Using Barcode generator for .NET framework Control to generate, create Universal Product Code version A image in VS .NET applications.
[2] Note that initialization to the empty string for nested string members was introduced with CORBA 23 In CORBA 22 and earlier versions, you must explicitly initialize nested string members
Barcode Creator In Java
Using Barcode drawer for Java Control to generate, create barcode image in Java applications.
If you look at the generated code for your ORB, you may find that the actual name of this class is something other than String_mgr, such as String_item or String_member The exact name is not specified by the C++ mapping For the remainder of this book, we use the name String_mgr whenever we show a string that is nested inside another data structure A word of warning: do not use String_mgr (or its equivalent) as a type in your application code If you do, you are writing non-portable code because the name of the type is not specified by the C++ mapping Instead, always use String_var when you require a managed string type Apart from the initialization to the empty string, String_mgr behaves like a String_var After you assign a string to the member alphabetic, the structure takes care of the memory management for the string; when the structure goes out of scope, the destructor for alphabetic deallocates its string for you String_mgr provides the same conversions as String_var, and String_mgr and String_var can be freely assigned to each other, so you can effectively forget about the existence of String_mgr Automatic memory management is common to all structured types generated by the mapping If a structure (or sequence, union, array, or exception) contains (perhaps recursively) a variable-length type, the structure takes care of the memory management of its contents To you, this means that you need worry about the memory management only for the outermost type, and you need not worry about managing memory for the members of the type Here is an example to make this concept more concrete:
