java.beans
Interface DesignMode

All Known Subinterfaces:

BeanContext, BeanContextServices

All Known Implementing Classes:

BeanContextServicesSupport, BeanContextSupport

public interface DesignMode

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.

Since:

1.2

Field Summary

Modifier and Type	Field and Description
static String	PROPERTYNAME The standard value of the propertyName as fired from a BeanContext or other source of PropertyChangeEvents.

Method Summary

Modifier and Type	Method and Description
boolean	isDesignTime() A value of true denotes that JavaBeans should behave in design time mode, a value of false denotes runtime behavior.
void	setDesignTime(boolean designTime) Sets the "value" of the "designTime" property.

Field Detail

PROPERTYNAME

static final String PROPERTYNAME

The standard value of the propertyName as fired from a BeanContext or other source of PropertyChangeEvents.

Method Detail

setDesignTime

void setDesignTime(boolean 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.

Parameters:

designTime - the current "value" of the "designTime" property

See Also:

BeanContext, BeanContextMembershipListener, PropertyChangeEvent

isDesignTime

boolean isDesignTime()

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.
