Class FeaturesProcessorImpl

java.lang.Object

org.apache.karaf.features.internal.service.FeaturesProcessorImpl

All Implemented Interfaces:

FeaturesProcessor

public class FeaturesProcessorImpl
extends Object
implements FeaturesProcessor

Configurable FeaturesProcessor, controlled by several files from etc/ directory:

• etc/overrides.properties: may alter bundle versions in features
• etc/blacklisted.properties: may filter out some features/bundles
• etc/org.apache.karaf.features.xml (new!): incorporates two above files and may define additional processing (changing G/A/V, adding bundles to features, changing dependency attributes, ...)
