Exception Classes of Object Services

The exception classes of Object Services start with the prefix CX_OS_. The exceptions of category CX_DYNAMIC_CHECK are propagated to the caller by Object Services and must be handled by the user.

The subclasses CX_OS_NO_CHECK_CONTAINER and CX_OS_MIGRATION of CX_NO_CHECK are for internal purposes: The first, as a container, allows exceptions of the CX_DYNAMIC_CHECK category from internal event handlers to be propagated, while the second is used for migration purposes.

For a more detailed description of the exception classes, see the relevant class documentation.
