Interface DesignMode
- BeanContext, BeanContextServices
- BeanContextServicesSupport, BeanContextSupport
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.
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).
|
PROPERTYNAME
public static final String PROPERTYNAME
Use this name when firing PropertyChangeEvents from your Bean.
isDesignTime
public boolean isDesignTime()
This method should tell whether it is design time or runtime.
true if design time, false if
runtime.
setDesignTime
public 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).
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.
designTime - the new value of design time,
true if it is design time,
false if it is runtime.
