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.

  • Field Summary

    Fields
    Modifier and Type Field 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 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 Details

    • PROPERTYNAME

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

  • Method Details

    • 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.
