# Class QueryProfilerResult

java.lang.Object
org.apache.lucene.sandbox.search.QueryProfilerResult

public class QueryProfilerResult extends Object
This class is the internal representation of a profiled Query, corresponding to a single node in the query tree. It is built after the query has finished executing and is merely a structured representation, rather than the entity that collects the timing profile.

Each QueryProfilerResult has a List of QueryProfilerResult, which will contain "children" queries if applicable
