### Available Classes in ABAP for Cloud Development
If available to you, you have accessed an [SAP BTP ABAP Environment](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abensap_btp_abap_env_glosry.htm) using the [ABAP development tools for Eclipse (ADT)](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abenadt_glosry.htm).
Access to SAP-provided repository objects is restricted to objects that have been released for [ABAP for Cloud Development](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abenabap_for_cloud_dev_glosry.htm) ([released APIs](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abenreleased_api_glosry.htm)). You can find the released repository objects in the *Project Explorer* view in ADT under *Released Objects*. The classes are located in the *Source Code Library* folder:

Exception classes are special classes, usually starting with the name <code>CX_*</code>, that serve as the basis for <a href="https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abencatchable_exception_glosry.htm">catchable exceptions</a>. When an exception is raised, an object of such an exception class is created. There are several predefined exception classes. Find more information in the [Exceptions and Runtime Errors](27_Exceptions.md) cheat sheet.
