Short Reference
ABAP Syntax
[EXCEPTIONS exc1 = n1 exc2 = n2 ... [OTHERS = n_others]].
What does it do? The additions EXPORTING and EXCEPTIONS are used to pass actual parameters to the instance constructor statically or to assign return codes to non-class-based exceptions.
When using the addition EXPORTING , you must specify the non-optional input parameters p1 p2 ... of the instance constructor of the instantiated class using the type-specific actual parameters a1 a2 ... . You have the option of specifying the optional input parameters. As in regular method calls, a1 , a2
, ... are general expression positions . In other words, functions and expressions can be passed as actual parameters, alongside data objects.
Special rules apply in this case. If a subclass does not have an instance constructor implemented explicitly, the interface of the instance constructor from the next-highest superclass that explicitly implements the instance constructor is used.
The addition EXCEPTIONS can be used to assign return values to non-class-based exceptions exc1 exc2... .
The syntax and semantics are the same as in the parameter list for static method calls .
Example ABAP Coding The following example illustrates how a dialog box of the Control Framework ( CFW ) is created and how input parameters are passed to the instance constructor of the global class CL_GUI_DIALOGBOX_CONTAINER . The class is defined implicitly using the static type of the reference variable dialog_box .
DATA dialog_box TYPE REF TO cl_gui_dialogbox_container.
CREATE OBJECT dialog_box
EXPORTING parent = cl_gui_container=>desktop
width = 1000
height = 350.
