package java.beans;
This interface is intended to be implemented by, or delegated from, instances
of java.beans.beancontext.BeanContext, in order to propagate to its nested hierarchy
of java.beans.beancontext.BeanContextChild instances, the current "designTime" property.
The JavaBeans™ specification defines the notion of design time as is a
mode in which JavaBeans instances should function during their composition
and customization in a interactive design, composition or construction tool,
as opposed to runtime when the JavaBean is part of an applet, application,
or other live Java executable abstraction.
Author: Laurence P. G. Cable See Also: Since: 1.2

/**

static String PROPERTYNAME = "designTime";
Sets the "value" of the "designTime" property.
If the implementing object is an instance of java.beans.beancontext.BeanContext,
or a subinterface thereof, then that BeanContext should fire a
PropertyChangeEvent, to its registered BeanContextMembershipListeners, with
parameters:
propertyName - java.beans.DesignMode.PROPERTYNAME
oldValue - previous value of "designTime"
newValue - current value of "designTime"
Note it is illegal for a BeanContextChild to invoke this method
associated with a BeanContext that it is nested within.
Params: - designTime – the current "value" of the "designTime" property

void setDesignTime(boolean designTime);
A value of true denotes that JavaBeans should behave in design time
mode, a value of false denotes runtime behavior.
Returns: the current "value" of the "designTime" property.
