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

[Manik Surtani (JIRA)]

     [ https://issues.jboss.org/browse/ISPN-3200?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Manik Surtani updated ISPN-3200:
--------------------------------

    Description: 
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}

  was:
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.
