Examples of org.osgi.framework.Filter.match()

org.osgi.framework.Filter.match()
Filter using a service's properties.
This {@code Filter} is executed using the keys and values of thereferenced service's properties. The keys are looked up in a case insensitive manner. @param reference The reference to the service whose properties are usedin the match. @return {@code true} if the service's properties match this{@code Filter}; {@code false} otherwise.
