Class GraphEventHandler

java.lang.Object
oracle.dss.graph.GraphEventHandler

public class GraphEventHandler

extends java.lang.Object

Event Handler to support Graph interactivity (such as Zoom and Scroll) without the ADF Faces layer. Applications developers generally do not need to use this class.

Method Detail

handleEvent

public static java.lang.Object handleEvent(CommonGraph graph,
                                           java.util.Map<java.lang.String,java.lang.String> params)

Generic handler for all graph events. The method should be used in conjunction with GraphXMLWriterCallback to support encoding and decoding of event payloads.

Parameters:

graph - the CommonGraph instance to which the event belongs

params - the event parameters sent from the client

Returns:

an Object providing context about the event

• null: if no additional context is necessary
• TimeSelectorEvent: if the user manipulated the time selector
