Class TopicMapFilter<T>

java.lang.Object
  com.antelmann.sql.TopicMapFilter<T>

All Implemented Interfaces:

CascadingFilter<T>, Filter<T>, Serializable

public class TopicMapFilter<T>
extends Object
implements CascadingFilter<T>, Serializable

a special filter that works very similar to an SQLMapFilter, but one instance can be applied to different stores with different mappings - based on the topics. Its embedded map is automatically translated via MappingInfo.getMappingForTopic(Object) by a BaseRowMapper. Note that if a given topic is not supported by the mapper itself, that restriction simply doesn't apply.
