1. Standard Display
The Object Display tool enables you to display classes and their instances (objects) together with their technical attributes. It consists of two views, which are represented by the tabs Objects and Display. The Objects tab contains the names of the objects previously selected by the user and their current status (visibility in the current program context) in the form of a history for special data objects.
To see the Individual Display, double-click the name of an object. The object name and the view of the object are displayed. If the object is addressed via a reference variable, the name of the reference is also displayed. The attributes of the object or class are listed in a table below. The following attributes are displayed:
- Status (attribute from a superclass)
- Binding (static or instance attribute)
- Visibility (private, public, protected)
- Attribute (name)
- Value type
- Value
- Hexadecimal value
- Technical type
- Absolute type
- Alias
- Full name
- Read-only flag
The standard services provided allow you to search in the object attributes and save the individual display of an object as a local file.
The entry in the Object field gives
information on the type of object that is described in the chapter Names of Anonymous
Storage Objects. It is used in the same manner for the classic and for the
new Debugger.
In the View field, you can use the F4
help to select a superclass or interface from the inheritance hierarchy of the
object. The system then displays only the attributes inherited from this
superclass (and its superclasses) or the attributes contained in the selected
interface.
2. Special Functions
There are functions available for displaying attributes, events, references, and inheritance hierarchies, which are available in the form of icons below the View input field.
The first time the Object Display tool is called, the system branches to the attributes list. The objects are listed according to class affiliation in the sequence of their class hierarchy. The hierarchical display can be cancelled by activating the function in the icon Superclass on/off, which is directly beside the View input field.
If you call the Display Results function, the event list is displayed. Their handlers will be visible if you expand the event node that is shown on the screen. As with the attributes, you can limit the events in the View field.
If you call the Display References function, the references list is displayed. Their names are the same as those given in the section Names of Anonymous Storage Objects. Finally, the Inheritance Hierarchy function displays the entire inheritance hierarchy in tree form. Setting limitations for the view is not possible for these two functions.
In the references and results displays, the standard services Search and Save as Local File are available, while only the latter is available in the inheritance hierarchy display.
3. Navigation
So that an object or a data object can be included in the object display at all, you first need to double-click the object name in the Variable column of the Overview of Variables. In the individual display, simply double-click on a component of the object and you will get to the appropriate special display.
