Method Detail

isNeedsMostCurrentEvents

boolean isNeedsMostCurrentEvents()
                                 throws IOException,
                                        AutomationException
Indicates whether a list of the most current events is needed so they might be rendered differently than the older events.

Description

Reports if Most Current Event Rendering is enabled for this renderer. Most Current Event Rendering allows the newest event to be rendered differently than the rest of the events in a tracks.

Remarks

Product Availability

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

Returns:
The pvbNeedsMostCurrent
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

getHistory

int getHistory()
               throws IOException,
                      AutomationException
Indicates the number of history events composing the track that will be used to represent the track line.

Description

The History property trims the length of the track line displayed when tracks are enabled in the renderer.

Remarks

Setting the History to zero will draw the entire track.

Setting the history for a track does not effect the rendering of its events.

Product Availability

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

Returns:
The pNumEvents
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

setHistory

void setHistory(int pNumEvents)
                throws IOException,
                       AutomationException
Indicates the number of history events composing the track that will be used to represent the track line.

Product Availability

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

Parameters:
pNumEvents - The pNumEvents (in)
Throws:
IOException - If there are interop problems.

                       throws IOException,
                              AutomationException
Indicates if the track symbology is smooth or not.

Description

Applies a bezier curve to the track lines. This way track lines do not appear to make abrupt changes of direction.
