Flipping a boolean return value from a method

former_member333493 — Thu, 18 Jul 2019 15:40:29 GMT

I have a public static method in a class which has a returning variable of type BOOLE ('X' for true, ' ' for false). I want to store the negation of the value returned by this method into a variable lv_result (type c length 1). Is this possible without the use of a third variable?

Ideally I'm roughly looking for something as follows:

LV_RESULT = ( NOT cl_class_api=>method (EXPORTING iv_var = lv_var) ).

Use boolc or xsdbool:

LV_RESULT = xsdbool( abap_false = cl_class_api=>method( EXPORTING iv_var = lv_var) ).

(if the method returns false then it gives true, and if the method returns true then it gives false)

Apart from abap_false in place of false, this seems perfect.
