Interface DataFilter

public interface DataFilter

Data Filter
Data filters are used to transform data as it is sent to a Channel. Messages are filtered as the message is published to a channel, invoking the Channel.publish(Message) method.
This method gets invoked in two different scenarios, the first being when a message is received from a remote client, and the Bayeux implementation invokes the publish method directly. The second scenario is when a local client invokes Channel.publish(Message) directly in the local JVM.
