out->write in the main method of classes that implement interface if_oo_adt_classrun in order to write the content of ABAP data objects to a text console.You might also know the interface
if_demo_output implemented by class cl_demo_output that also offers a method write that does mostly the same.What you might don't know is the fact that the implementations of the ABAP console in ADT and of
cl_demo_output are two sides of the same coin. When the ABAP console was introduced some years ago, its internal implementation was copied from cl_demo_output and cl_demo_output_stream (the latter produces an output-friendly XML). But since ADT used an early stage of cl_demo_output, it missed its continuous improvements that took place in the meantime. An example is the implicit retrieval of the data object's name if no name is passed explicitly.Recently,
cl_demo_output was invigorated significantly by being able to handle any ABAP data object including complex types like nested structures or tables and data as well as object references (see the blog CL_DEMO_OUTPUT invigorated). In the blog it is still stated that the new features are available in HTML mode of cl_demo_output only. Meanwhile, even that has changed. A clever working student (a physicist) has done it and "reprogrammed a browser in cl_demo_output_text"! With other words, the content of arbitrary ABAP data objects can be displayed in a console-type text format.Thus, with Releases 2308/2023, what belongs together grows together. The ABAP console of ADT skipped the old implementation and calls the implementation of
cl_demo_output instead. As a result, you don't have to care about your data types anymore. And the best is, you have to do nothing for that. The enhancement comes for free.Old release:
As of 2308/2023:

If you know
if_demo_output, you might also know that it contains much more methods than if_oo_adt_classrun that is the standard type of parameter out which allows to call methods WRITE and GET only. In order to stay compatible, the interface if_oo_adt_classrun was not changed. Nevertheless, if_demo_output can also be used for the ABAP console; Instead of implementing if_oo_adt_classrun in your class, you can inherit from the new abstract class cl_demo_classrun and redefine its method main. In cl_demo_classrun you have access to an intance attribute out of type if_demo_output and thus you can use all methods of cl_demo_output. cl_demo_classrun and if_demo_outputare released for ABAP Cloud with 2311/2023.Most example programs of the ABAP Keyword Documentation have been switched to classes following that pattern and thus were made executable by F9:
