    [ https://issues.apache.org/jira/browse/KARAF-3271?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14165163#comment-14165163 ] 

Jean-Baptiste Onofré commented on KARAF-3271:
---------------------------------------------

This method already exists. See https://git-wip-us.apache.org/repos/asf?p=karaf.git;a=blob_plain;f=features/core/src/main/java/org/apache/karaf/features/FeaturesService.java;hb=karaf-3.0.x:

{code}
boolean isInstalled(Feature f);
{code}

You can also directly list only installed features:

{code}
Feature[] listInstalledFeatures();
{code}

> I am using org.apache.karaf.features.FeatureService to query all Features installed on the system.  After acquiring all the features I'd like to have feature.isInstalled() available.
> Currently as a work around I'm calling listFeatures()/listRepositories() then afterwards making a call to featureService.isInstalled() for each feature.
