[infinispan-issues] [JBoss JIRA] (ISPN-3200) Allow KeyFilters to be applied to listeners

Allow KeyFilters to be applied to listeners ------------------------------------------- Key: ISPN-3200 URL: https://issues.jboss.org/browse/ISPN-3200 Project: Infinispan Issue Type: Feature Request Components: Listeners Affects Versions: 5.3.0.Final Reporter: Manik Surtani Assignee: Manik Surtani Labels: leads Fix For: 6.0.0.Beta1, 6.0.0.Final When registering a listener, users should be able to provide a {{KeyFilter}}, a simple interface that determines whether a listener is invoked or not based on whether the affected key(s) matches the filter. The proposed API may overload the {{addListener(Object listener)}} method on {{Cache}}, adding: {code} void addListener(Object listener, KeyFilter filter); {code} where {{KeyFilter}} may be an interface that looks like: {code} public interface KeyFilter { boolean match(Object key); } {code}
