Description

In this example, a call of a method to_string transforms the lines of the internal table carriers after the FOR expression to a text string. This string is then passed to the instance method WRITE of an object of the class CL_DEMO_OUTPUT. This object is created after INIT and referenced by the local reference variable o. The return value of the method WRITE returns a reference to its own object, which means that the assignment to o does not modify its value but meets the syntax rule that o must be filled. At the end of processing, the reference to the object in o is assigned to the reference variable out and the content of the internal table written to the object can be displayed using the method DISPLAY.
