public class TADynamicDisplayRefreshController
extends Object
implements com.esri.arcgis.interop.RemoteObjRef, ITAUpdateControl, IActiveViewEvents, ISupportErrorInfo, IGlobeDisplayEvents, IDynamicMapEvents, ITxDocumentEvents, IDisplayEvents, ITxActiveTrack, ITxHighlightSettings

Manages all dynamic updates to all of ArcMap's maps, both in the map view and the page layout view.

Description

This Object is responsible for managing all dynamic updates to all of ArcMap's Maps, both in the MapView and the Page Layout View. This object will allow the configuration of the maintenance update interval, the dynamic update maximum rate, and will ensure that multiple dynamic updates are syncronized with general ArcMap screen updates.

The following text describes the general approach that we are going to use, as a first stab, for dynamic updates.

1) Maintain a list of all Temporal layers and map them to Identifiers that uniquely identify a dynamic feature source (Feature class)

2) Provide a interface method that Informs the Object that a substantial change has occured within a feature class

3) Upon reciept of a call to method described above, ensure that the last update completion time is greater than the minimum update rate. If not then issue a ShortUpdate Draw Request.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server. Requires Tracking Analyst Extension.

Constructor Detail

TADynamicDisplayRefreshController

public TADynamicDisplayRefreshController(Object obj)
                                  throws IOException
Construct a TADynamicDisplayRefreshController using a reference to such an object returned from ArcGIS Engine or Server. This is semantically equivalent to casting obj to TADynamicDisplayRefreshController.
Casting to this class from the return value of a method will not work, as this class represents an abstract class in ArcObjects.
*
TADynamicDisplayRefreshController o = (TADynamicDisplayRefreshController)obj; // will not work

TADynamicDisplayRefreshController o = new TADynamicDisplayRefreshController(obj); // Use this constructor instead
* @param obj an object returned from ArcGIS Engine or Server

Throws:
IOException - if there are interop problems TADynamicDisplayRefreshController theTADynamicDisplayRefreshController = (TADynamicDisplayRefreshController) obj;

Indicates the maximum duration between map display refreshes, as defined in the dynamic update controller.

Remarks

Gets and sets the maximum number of seconds between map refreshes if no new data has been received when AutoRefresh is enabled on the dynamic update controller. If no new data has been received to trigger an update refresh this timer will cause the map to refresh. This is important for maintaining time windows and aging. The RefreshRate must be greater than or equal to the MaxUpdateRate and less than or equal to 500 seconds.

This timer is triggered only if new data has been received since the last refresh. If data stops being received for an extended period the timer specified by the RefreshRate property will execute to maintain temporal windows and aging.

Supported Platforms

Windows, Solaris, Linux

Specified by:
itemDeleted in interface IActiveViewEvents
Parameters:
theEvent - The event
Throws:

AutomationException - If the ArcObject component throws an exception.

itemReordered

public void itemReordered(IActiveViewEventsItemReorderedEvent theEvent)

Remarks

The Map objects only fire this event whenever IMap::MoveLayer is called. In the ArcMap application, this occurs when you reorder layers in the table of contents. The Map will also fire this event when new layers are added.

The PageLayout object fires this event when changing the order of graphics. For example, IGraphicsContainer::BringToFront, PutElementOrder, SendToBack, SendBackward, and BringForward all fire this event. These functions are on ArcMap's Drawing menu under the Order pull right menu. Although the Map object is also a graphics container, it does not fire this event when its graphics are reordered.

viewRefreshed

public void viewRefreshed(IActiveViewEventsViewRefreshedEvent theEvent)
                   throws IOException,
                          AutomationException
Fired when view is refreshed before draw happens.

Description

Method that gets fired in response to IActiveView::Refresh and IActiveView::PartialRefresh.

Remarks

This event is useful in the case where you're watching for something to change in the view and there aren't any specific events for that change (e.g. ContentsChanged, ItemAdded). You can always listen for this method as a last resort. Care must be taken however to be very efficient in your implementation of this event because it will be called quite often.

The event parameters directly coincide with the arguments to IActiveView::PartialRefresh. For additional information about the arguments, see the help for that method.

If the event object connects to both the layout and a map, then the view parameter tells you which object initiated the event.

In an implementation of this method you typically want to check the phase and respond to only one. Otherwise, your code will execute multiple times per drawing sequence.

afterItemDraw

public void afterItemDraw(IActiveViewEventsAfterItemDrawEvent theEvent)
                   throws IOException,

Fired after an individual view item is drawn. Example: view items include layers in a map or elements in a page layout.

Remarks

AfterItemDraw can be used to execute after each individual item has drawn. Event firing can be an expensive operation (time consuming) when there are many layers in a map, however. As a result, the AfterItemDraw event is only fired when the IViewManger::VerboseEvents property is set to True. By default this property is False.

Throws:
IOException - If there are interop problems.

Description

Fired each time the dynamic map cycle ends, if the Dynamic Map is enabled.

This event is tied to the internal heart beat of the dynamic map and will get fired on every dynamic map heart beat, even if the dynamic map is not being redrawn.

Remarks

The dynamic map heart beat interval is set by the IDynamicMap.DynamicDrawRate property.

This event is useful when a timer mechanism is needed. This event synchronizes with the dynamic map heart beat.

beforeDynamicDraw

public void beforeDynamicDraw(IDynamicMapEventsBeforeDynamicDrawEvent theEvent)
                       throws IOException,
                              AutomationException
Fired before the specified phase is drawn.

Remarks

The BeforeDynamicDraw event is getting fired with two different phases (enum esriDynamicMapDrawPhase). Each phase has a different meaning and usage:

  1. esriDMDPDynamicLayers – This is getting fired on each dynamic cycle that the Dynamic Map re-renders the scene. The BeforeDynamicDraw event is fired just before the first layer is rendered, and AfterDynamicDraw event is fired just after the last layer (including any Graphic Layer) is rendered.
    In this context, there is an active OpenGL Rendering context (with a preset rendering volume, viewport, etc).
    Use this context to plug-in any custom dynamic drawings with the DynamicDisplay API as well as with the OpenGL API. This context can be useful in order to draw dynamic elements behind or on top of the Layers and Graphics, which do not need to be associated with a layer.
  2. esriDMDPLayers – When the Dynamic Map is sensing that it needs to fetch tiles in order to be able to render the scene, the BeforeDynamicDraw will get fired. When the last missing tile will be available and rendered the AfterDynamicDraw event will get fired.
    Note that it is not valid to use the DynamicDisplay API, nor the OpenGL API in this context, since the OpenGL Rendering Context is not fully setup.
    Use this context if you need to monitor when the Dynamic Map is still in a process of fetching tiles for rendering the display.
