Examples of org.apache.lucene.util.RamUsageEstimator

org.apache.lucene.util.RamUsageEstimator
Estimates the size of a given Object using a given MemoryModel for primitive size information. Resource Usage: Internally uses a Map to temporally hold a reference to every object seen. If checkIntered, all Strings checked will be interned, but those that were not already interned will be released for GC when the estimate is complete.
