# Building An Object

To build a wrapper object, you need to create an object specification about the exported object in the Export Bridge Assistant. This wrapper object is what your client application needs to use the IDL source object’s functionality.

Note that the wrapper object is only an interface between your client application and the IDL source object. That is, the Assistant does not include the entire IDL object in a wrapper object generated from it, but creates a COM or Java layer to interact with the source object. Furthermore, if you change the source object, you might affect an existing wrapper object exported from it (see Modifying a Source Object After Export).

Important topics regarding building an object include the following:

- Understanding the object status for exporting (Exporting an Object)
- What information you need to specify when exporting an object (Specifying Information for Exporting)
- Java and COM types supported by the Export Bridge technology (Supported Data Types)
- What gets skipped for exporting (Information Skipped During Export)
- How to export superclasses (Exporting a Source Object’s Superclasses)
- What to do with a modified object after exporting (Modifying a Source Object After Export)
