eu.bandm.tools.message

Class MessageLocationFilter<D>

java.lang.Object

eu.bandm.tools.message.SingleSender<SimpleMessage<D>>

eu.bandm.tools.message.MessageLocationFilter<D>

All Implemented Interfaces:

MessageReceiver<SimpleMessage<D>>

public class MessageLocationFilter<D>
extends SingleSender<SimpleMessage<D>>
implements MessageReceiver<SimpleMessage<D>>

A filter which propagates only those messages which lie in certain areas of locations. These are given by triples (String, fromLine, toLine), with toLine exclusive. Only line numbers of locations are compared. The string must appear as a SUFFIX of the String.valueOf of the DocId. This seems a "crude" method, but is very adequate to practice. All other add/remove methods convert to this format.
Additional boolean parameters determine whether to pass or suppress location-less messages, and if no regions specified means ALL or NONE to pass.
