Interface DesignMode

All Known Implementing Classes:

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

Method Detail

setDesignTime

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.

Parameters:

designTime - the new value of design time, true if it is design time, false if it is runtime.

PropertyChangeEvent, BeanContext, PROPERTYNAME

isDesignTime

boolean isDesignTime()

This method should tell whether it is design time or runtime.

Returns:

true if design time, false if runtime.
