java.beans
public interface DesignMode
BeanContextChild implementors implement this to get information
about whether they are in a design time or runtime environment.
The reason this is restricted to BeanContextChildren is that
only things in the BeanContext hierarchy are given this
information in the first place.
Since: JDK1.2

| Field Summary | |
|---|---|
| String | PROPERTYNAME
Use this name when firing PropertyChangeEvents from your Bean. |
| Method Summary | |
|---|---|
| boolean | isDesignTime()
This method should tell whether it is design time or runtime. |
| void | setDesignTime(boolean designTime)
The environment will call this method on your
BeanContextChild when it is registered in a parent
BeanContext or when behavior needs to switch from
design time to runtime behavior (or vice versa).

PropertyChangeEvents from your Bean.Returns: true if design time, false if
runtime.
BeanContextChild when it is registered in a parent
BeanContext or when behavior needs to switch from
design time to runtime behavior (or vice versa).
BeanContexts are required to fire
PropertyChangeEvents when properties change.
designTime is a property, and therefore when you
implement setDesignTime(), you need to fire a
PropertyChangeEvent with the old value, the new
value and using PROPERTYNAME as the property name.
Parameters: designTime the new value of design time,
true if it is design time,
false if it is runtime.

UNKNOWN: I'm frankly not really sure whether it's the case that the BeanContext can change the status of the Bean from design time to runtime. But it appears that it may be so.
