public class TemporalRenderer
extends com.google.gwt.core.client.JavaScriptObject

Temporal renderers provide time-based rendering of features in a feature layer. It can be useful to visualize historic or real-time data such as earthquake or hurricane occurances. You can use a temporal renderer to define how observations (regular, historic, latest) and tracks are rendered. You can also show aging of features with respect to the map's time extent.

public static TemporalRenderer create(Renderer observationRenderer)

Creates a new TemporalRenderer object that can be used with a time-aware feature layer.

Parameters:

observationRenderer - - Renderer for regular/historic observations.

Returns:

TemporalRenderer

create

public static TemporalRenderer create(Renderer observationRenderer,
                      Renderer latestObservationRenderer,
                      Renderer trackRenderer,
                      SymbolAger observationAger)

Creates a new TemporalRenderer object that can be used with a time-aware feature layer.

Parameters:

observationRenderer - - Renderer for regular/historic observations. Required.

latestObservationRenderer - - Renderer for the most current observations. Optional.

trackRenderer - - Renderer for the tracks. A track is a collection of events that share a common track ID. A track line is a graphic line that connects the observations. Applicable only for feature layers with a valid trackIdField. Optional.

observationAger - - Symbol ager for regular observations. Optional.

Returns:

TemporalRenderer

public final Symbol getSymbol(Graphic graphic)

Returns the symbol used to render the graphic.

Parameters:

graphic - - The input graphic.

Returns:

Symbol
