public class TrackMessageSizeFilter extends Object implements PerRequestBroadcastFilter
PerRequestBroadcastFilter implementation that add the expected length of the message. This is
useful when used with the atmosphere.js library as the library will read the expected size and wait for the
entire messages to be received before invoking its associated callback.
NOTE: The broadcasted message MUST BE a String. If your application is broadcasting another object, you need to
write your own Filter.
If you aren't using atmosphere.js, you need to add the HeaderConfig.X_ATMOSPHERE_TRACKMESSAGESIZE header in order to
enable that Filter. The delimiter character used is '|'.
For example, broadcasting String 'helloword' will be received by the client as '9|helloword' but delivered as 'helloword'
to the Javascript function/callback.BroadcastFilter.BroadcastActionVOID_ATMOSPHERE_RESOURCE_UUID| Constructor and Description |
