Replace header names and protocol names with IDs ------------------------------------------------ Key: JGRP-932 URL: https://issues.jboss.org/browse/JGRP-932 Project: JGroups Issue Type: Feature Request Reporter: Bela Ban Assignee: Bela Ban Fix For: 2.10 We currently use strings as header names. Since a header has to have a magic number, we can replace strings with shorts. A short is always 2 bytes and we don't need to send (potentially long) names around. A message would then have a Headers hashmap of shorts and Headers. A protocol would also have to be able to catch its own headers, e.g. by creating a method getId(). UDP.getId() might return 56, which is the value in jg-magic-map.xml for TpHeader. This will solve https://jira.jboss.org/jira/browse/JGRP-872.
