By default, when you save in Eclipse, a codesync is automatically performed. For large components, you may not want this option selected because of the delay involved in synchronizing; however, if this feature is not enabled, synchronization does not occur.
Note: In Eclipse, if you select Save > Save All, a codesync will not be performed if more than one file was saved; codesync occurs only when you save one file at a time..
Because Eclipse and Rational Rose RealTime share a common file system, you must use caution when modifying code and building. For example, you can modify code for a model element in Rational Rose RealTime, and then modify the same method in Eclipse for that corresponding model element. Saving the changes in Eclipse (which will cause a codesync to be performed in Rational Rose RealTime) will overwrite the initial changes you made to the model element in Rational Rose RealTime. In addition, if you modify a method in Eclipse without saving, generating the component in Rational Rose RealTime overwrites the modifications you made in Eclipse. We strongly recommend that you save and build your changes as often as possible.
