      y - th y coordinate of the bean

  • Method Details

    • init

      public static void init()
      Sets up just a single collection of bean instances in the first element of the list. This is useful for clients that are using XMLBeans to load beans.

    • removeAllBeansFromContainer

      public static void removeAllBeansFromContainer(JComponent container, Integer... tab)
      Removes all beans from containing component
      Parameters:
      container - a JComponent value

    • addAllBeansToContainer

      public static void addAllBeansToContainer(JComponent container, Integer... tab)
      Adds all beans to the supplied component
      Parameters:
      container - a JComponent value

    • getBeanInstances

      public static Vector<Object> getBeanInstances(Integer... tab)
      Return the list of displayed beans
      Parameters:
      tab - varargs parameter specifying the index of the collection of beans to return - if omitted then the first (i.e. primary) collection of beans is returned
      Returns:
      a vector of beans

    • setBeanInstances

      public static void setBeanInstances(Vector<Object> beanInstances, JComponent container, Integer... tab)
      Adds the supplied collection of beans at the supplied index in the list of collections. If the index is not supplied then the primary collection is set (i.e. index 0). Also adds the beans to the supplied JComponent container (if not null)
      Parameters:
      beanInstances - a Vector value
      container - a JComponent value

    • addBeanInstances

      public static void addBeanInstances(Vector<Object> beanInstances, JComponent container)
      Adds the supplied collection of beans to the end of the list of collections and to the JComponent container (if not null)
      Parameters:
      beanInstances - the vector of bean instances to add
      container -

    • removeBeanInstances

      public static void removeBeanInstances(JComponent container, Integer tab)
      Remove the vector of bean instances from the supplied index in the list of collections.
      Parameters:
      tab - the index of the vector of beans to remove.

    • paintLabels

      public static void paintLabels(Graphics gx, Integer... tab)
      Renders the textual labels for the beans.
      Parameters:
      gx - a Graphics object on which to render the labels

    • getStartPoints

      public static List<BeanInstance> getStartPoints(Integer... tab)
      Returns a list of start points (if any) in the indexed flow
      Parameters:
      tab - varargs integer index of the flow to search for start points. Defaults to 0 if not supplied.
      Returns:
      a list of BeanInstances who's beans implement Startable

    • findInstance

      public static BeanInstance findInstance(String beanName, Integer... tab)
      Search for a named bean in the indexed flow
      Parameters:
      beanName - the name of the bean to look for
      tab - varargs integer index of the flow to search in
      Returns:
      a matching BeanInstance or null if no match was found

    • findInstance

      public static BeanInstance findInstance(Point p, Integer... tab)
      Looks for a bean (if any) whose bounds contain the supplied point
      Parameters:
      p - a point
      Returns:
      a bean that contains the supplied point or null if no bean contains the point

    • findInstances

      public static Vector<Object> findInstances(Rectangle boundingBox, Integer... tab)
      Looks for all beans (if any) located within the supplied bounding box. Also adjusts the bounding box to be a tight fit around all contained beans

    • addBean

      public void addBean(JComponent container, Integer... tab)
