Interface IMessageFilter

interface IMessageFilter
Extends com.amazon.apmf.IStandard A message filter, used to describe which messages are forwarded to a given listener registered via IMessagingModule::registerMessageFilter(). This interface is intentionally an opaque capability token. Filter matching logic executes server-side in the Message Router process, so there is nothing for clients to introspect or modify after construction. Instances are created by IMessageFilterBuilder and consumed by IMessagingModule::registerMessageFilter().
