Bela Ban created JGRP-2481: ------------------------------ Summary: Use IdentityHashmap in Util.TYPES and ClassConfigurator Key: JGRP-2481 URL: https://issues.redhat.com/browse/JGRP-2481 Project: JGroups Issue Type: Enhancement Reporter: Bela Ban Assignee: Bela Ban Fix For: 5.0.0.Beta2 When we have lookup hashmaps, populated at startup, and not changed afterwards, we can use IdentityHashmaps, as a {{get()}} is constant. For keys with a contiguous range (e.g. {{[1 .. 20]}}), we might even use a simple array of keys and values, e.g. {{[K1,V1,K2,V2, ... Kn,Vn}}. -- This message was sent by Atlassian Jira (v7.13.8#713008)
